RAVPower Q&A: We Answered Your Most Common Questions

RAVPower Q&A FAQ Questions Answers About Help Customer Service

When it comes to charging, we have heard it all before. From questions about speeds, battery sizes, and USB ports, our awesome service team know the answers and are always happy to help. Below they have answered 10 of the most common questions fans ask us at RAVPower.


Q1: Why Does It Take so Long Time to Charge My Mobile Device?

This is depends on what activity your phone is doing. As covered in our battery saving tips post, some activity like streaming music rapidly uses your battery, while other methods like closing apps make little difference. To increase the efficiency of the charge we suggest:

  • Use the correct charging cable
  • Stop playing music and watching films
  • Turn off push notifications, email retrieval methods, or any part of the phone that is communicating with the outside world
  • Stop using your device (this is a drastic and bold choice)

Q2: Can Devices like a Go Pro, MP3 Player, Kindle, Camera, Earphone, Laptop, Drone, or Other Devices Be Charged?

This depends on the voltage of the connected device. Our portable chargers have a 5V output voltage which can typically charge devices from 4.5V-5.5V. A laptop has an output voltage between 11V-21V; therefore, a portable charger cannot charge a laptop.

Always check the voltage and charging current of the connected device to see if it is within the listed range. That said GoPros and Kindles can be recharged with a portable charger as can most MP3 players, headphones, cameras, and drones. Even the Nintendo Switch can be charged.


Q3: Why Did the Power Bank Recharge My Device Only Twice?

It depends on the capacity of the power bank and the battery capacity of your mobile device. A smaller sized power bank will charge your phones less times than a large sized one.


Here is how to calculate it so you know if you next power bank will provide 2, 4 or more charges:

Labeled capacity of the power bank x 3.7 / output voltage of power bank x 0.85 / battery capacity of device = Total number of recharges


If you were using a 16000mAh power bank and wanted to find out how many times you can charge your iPhone 8, you would input the formula like so:

16000 x 3.7 / 5 x 0.85 / 1821 = 7.7 charges

We can expect 7.7 recharges of the iPhone 8 from a power bank with a 16000mAh capacity.

For full details, see our full post on how many times your power bank can recharge a smart phone.

Q4: What Can I Do If the USB Port Connected Get Loose or Falls into the Portable Charger?

Please contact our customer support team at support@ravpower.com to get a FREE replacement. We also suggest that you do not pull or plug in the USB cable with extra force in order to prevent damage to the USB port.


Q5: How Many Charging Cycles Does My Portable Charger Have? What Is the Approximate Lifetime?

Most RAVPower Portable Chargers use high-density li-polymer battery cells, which can typically retain 70-80% of its power after 500 charge cycles. Considering the average person does not use it every day, you can get 2-3 solid years from a typical portable charger.


Q6: I Am Finding That My Portable Charger Does Cannot Continuously Charge My Device. What Can I Do?

Please check the following:

1) Please first confirm that there is enough battery in the portable charger

2) Please ensure you are using the original OEM charging cable or a RAVPower cable to charge your devices. You may need to pull and plug the cable a few times to ensure the IC chip registers a connection.

3) Please recharge your device with an AC charger to check whether the same problem occurs. If there are still issues, please contact our friendly RAVPower customer support team here.

Q7: How Long Does It Typically Take to Recharge a Portable Charger?

This depends on a few factors. This includes the size of the power bank, the type of charging cable used, how much power is currently in the power bank, and the type of charger used.

For example, a high capacity RAVPower 22000mAh Portable Charger will ordinarily take 11 – 12 to fully recharge with a 2.4A charger. However, that time can be doubled if only using a 1A charger. That time is further compacted if using cheap knockoff cables instead of the OEM or reliable charging cables.


Q8: What Should I Do If My Portable Charger Fails to Recharge?  

If it fails to charge, the portable charger or the USB cable may be defective. You can do the following:

  1. Check that the AC adapter is securely connected. If the AC adapter is securely connected, you can replace it with a new one.
    Check that the USB cable is securely connected to your power bank and device. If it is and you still have trouble, please replace it with a new cable.
    c. If there is no problem with the AC adapter or the USB cable, the portable charger may be defective. In this case, please contact our support team in order to get a replacement.

Q9: Can I Charge A Device At The Same Time That A Portable Charger Recharges?

The simple yet complicated answer is… maybe. Our RAVPower power banks feature pass through technology so they can be recharged while they charge your phone. However, as we said in this post on pass through technology, you should limit the amount of time you do that.


Q10: Can I Use A RAVPower Charger All Around the World?

Both the voltage for input and output of the portable charger are DC 5V, which can charge mobile devices from anywhere in the world.

As for recharging the power bank, it depends whether the input voltage of the AC charger is compatible with the country you are travelling to.

For quick reference:
• Japan: AC 100V
• USA, Canada, Mexico: AC 120V
• Brazil, China, Hong Kong: AC 220V
• India, Australia, Singapore, Malaysia, the Philippines, and most countries in Europe: AC 230V

However, nearly all AC chargers these days are 100V-240V, so they can be used all around the world without issues.

    1. Hey Frank,
      Actually you can charge the power bank with the micro-USB input and USB-C input at the same time. However, but the micro-USB will not Quick Charge and can only charge at 5V. I hope this answers your question.

    1. Also to add onto this, is there a battery inside the RAVPower (Not the portable charger) if so is there a way to charge it?

    1. Hi JT,
      We’ve found that it is typically a problem with the charging cable rather than a power bank. It’s also quite common for iPhones.
      Here is what you can do:
      • Please re-plug the charging cable into your phone and into the power bank
      • Try clearing your iPhone’s charging port as since dust and oxidation can impact charging. Hopefully this helps you have a smooth charge.

  1. When you update your app for the RAVPower FileHub Plus with Wireless Travel Router? Is not compatible with ios11.

  2. Can i use my iphone x wall charger to charge the ravpower power bank or can it only be charged with a portable ravpower wall charger ?

      1. I just got this great looking charger as a gift.
        A few questions.
        One, what cable do I use to plug it into the wall when it charges. The only one that seems to fit is my Amazon kindle cable. Is that ok?
        Two, the cables that came with it don’t fit into my iphone, ipad. Can I just use the cables I use to charge them?
        Three, so basic. I”ve got a long long flight coming. Is the way to use it that I bring this with me and when the phone dies out I just plug it in and keep listening to my music while it charges? I assume that’s the point. But, hey, it was a gift so I’m not sure about how and when to use. Very confused about cables not fitting. THANK YOU SO MUCH.

        1. Hi Marco,
          1. Use a micro-USB cable. Plug the micro-USB into the power bank and the USB side into a USB charger. A USB charger is the type that comes with your iPhone and iPad.
          2. You will need a cable that is compatible with your phone. Just use the cables you already use.
          3. Yes you can bring it with you to charge your phone once it runs out of power. Please note when flying it needs to be taken on your carry-on as airplanes have strict rules about flying with lithium batteries. Here is a short post on the subject.

          Hope that helps.

  3. How can I know if my rav power is actually on or off? Yesterday I connected my device and it started charging and I looked at it 5 minutes after and it was not charging so it seemed the the ravpower turned off, there is only one button to check battery life so do I need to hold the button to turn it on/off? Thanks

      1. I have the same Issue, leave charging for 5 minutes and I come back to it, and I have to press the only bottom on the unit to start to charge again. Please help.

    1. Your device isn’t drawing enough amps to keep the power bank on and it is shutting itself off. I have this problem charging my earbuds

      I just plug my phone into the power bank to keep it charging

  4. Hello,
    I recently bought a Ravpower 22000mah power pack. It worked fin until last week, when it shows four dots when connected to wall power source, then when connecting to phone, the dots rapidly diminish to one, then goes out, and does not charge the phone. Is this a fault, or is there something I’m not doing right?
    Do I need to return for replacement, or can you send a replacement?
    Thanks, Ken

  5. For some reason, my rav power bank dies not charge when I plug it into a wall outlet and will only charge when I plug it into my laptop via sub. This is normal?

  6. Why does it stop charging once the phone reaches 100%. Will it start charging automatically once it drops a certain percentage?

  7. My ravpower bank does not charge anything.. The 4 lights is on the whole time.. The power button does not work either

    1. That’s very weird. Have you tried using a different cable? Please contact support@ravpower.com – our team will help resolve your issue, and if they cannot, they will reissue you a new power bank (if you are still in the warranty period). Sorry for any trouble!

  8. do I need to fully charge the power charger before use or does it arrive fully charged – thank you

  9. Hi,

    I was using the Ravpower to charge my IPad up last night and then looked at charging the Ravpower device today. I have plugged in the ravpower charger into the mains in order to charge the portable device and no lights is showing.

    Is this because the portable device has got no power and needs to be left to charge for a good few hours or is there a problem with the Ravpower device? I have charged the device before and the lights used to flash to show that is it charging.

    Can you please advise?

    Thank you for your help in advance.

  10. Can i charge my dell laptop with the AC output as the same time as i charge my phone with the USB ouput?

  11. I have a 32000mah ravpower battery. Ive been using it for a few months now, but today its been acting weird. I think I held the power button on the side for too long, but I dont know how to fix it now. Two of the blue lights keep flashing and it won’t charge anything. What should I do?

      1. Well that doesnt help me much. The two blue lights in the center are the ones flashing. Its never done this before and still hasnt stopped

    1. Thanks for the heads up. We checked here but there was no issue. Is it just on this blog post or on other blog posts? Please send a screenshot so we can fix immediately.

  12. Hi,

    I have a ravpower 26000 which has been brilliant, I use it on my bike attached to a dynamo and e-werk converter to charge my devices which I use on long distance trips. I previously asked a technical question to confirm if it allows simultaneous charge/discharge (I think you call it passthrough charging) so that I can charge from the dynamo whilst cycling and at the same time power my devices – bike sat nav and phone. The response confirmed that it supported this and it has worked brilliantly the longest trip so far was 3 months daily use on a 3000 mile tour without a single issue.

    I am reducing the weight on my bike for a lighter setup whilst touring and I am now looking at the 1650 rav power bank and I would like to confirm this also supports the simultaneous charge/discharge.

    The unit I am looking at is:




    I can’t work out which is the newer model and if they support passthrough charging, I would be grateful for your confirmation.

    Many thanks,

  13. I bought the PB-5055 27000 mah. However, when charging it with a 19V charger it comes with 8 lights. Then I pulled out and waited for a moment and pressed the power button to check the battery only four lights. Repeat the 19V rechargeable battery, and after a few minutes the lights come on again, while the batteries are not fully charged. Should I recharge 19V even if the lights are on?

  14. Traveling to Europe from the US this summer. What kind of adapter or converter will I need to charge my device in Europe? I have the RAVPower® 3rd Gen Deluxe 13000mAh External Battery.

  15. I have owned my RAVPower 26800mAh Portable charger for almost 7 months now and it has started to randomly stop charging my phone and start flashing all of the 4 dots at the same time. Do you know what I should do to fix it

      1. Would I still have that warranty even if I bought it off of amazon, because that is where I bought the charger at

  16. So my ravpower has been working great until yesterday, and I own the RP-PB052 model that has 22k mAh. Whenever I press or hold the power button the four lights come on for a brief second and then the two center lights flash for several seconds and that’s it. It won’t charge any of my devices and when I plug it into the charger it shows four lights so I no the battery isn’t dead. How can I fix this?

    1. Try with a different cable. If that doesn’t work then hold down the power button for 8 seconds to reverse the flow of power. If either solution doesn’t work, please let us know so we can help further.

      1. So I tried using three different cables and nothing changed and I also held down the power button for 8 seconds and it keeps doing the same thing. Any other suggestion or is it defective?

  17. I have the 4 port Ravpower RP-UC016 [4 port USB charger], and the quick charge outlet does not work. The others still do. Any suggestions?

    The QC outlet does not charge at all. Not even at slow rate.

  18. We bought two of the Ravpower Model RP-PB058.
    They are being used for commercial application to power low noise amplifier, which requires +5V, 100 ma.
    The Ravpower shuts down after 30 seconds.
    I suspect this is due to automatic shutdown when item being charged is fully charged, and the Ravpower is incorrectly deciding our load is a fully charged device.
    If this is the case, is there way to override the automatic power down feature?
    We are using special cable with the Data + and Data – lines connected to each other, which is advised to indicate to charger that at least 0.5A amps required.

    1. Unfortunately there is no way to overcome that. Considering people are trying more and more novel ways to use a power bank, perhaps in the future we will allow for more customization.

  19. Hi i have the ravpower element series 8000mah jump starter i have only used it once i got it from amazon this year.I fully charged it used it once put it away come to use it it was totally dead so put it on charge and nothing tried 3 different chargers cables left it for 24hrs still nothing any ideas ?

    1. It’s possible that either the battery has completely discharged or that it’s a defective unit. Since it’s a little hard to tell from the info you gave me, I will suggest you email support@ravpower.com so they can work with you to troubleshoot the potential cause and offer a solution.

      1. could be the case it has over discharged i used it once to charge my phone put it away after use and came to use it it does not charge left it a few day’s still nothing not had it a year yet.

  20. I recently purchased a RAVPower 26800 with the wall charger. I love it so far. I only have one issue. I read in the manual that when the device is fully charged, and still connected to the wall, the four blue lights will turn off after 10 secs. After the four lights came on, it’s been more than 4 hours and the lights are still on. Did I misunderstood how the lights work?


    1. Hey Edgar,
      Thanks for bringing that to our attention. Our product has been updated but not the manual. It is normal that the light will not turn off even after it is full recharged. Feel free to ask us anything else.

      1. I to am having more or less the same issue only the bottom of the four lights are blinking.. I just recieved this product and am hoping im worring over nothing but because of the outdated guides I wanted to makes sure its ok since I bought it off an eBay vendor

  21. My question is simple, is my ravpower fully charged when all 4 lights are blue with the 4th one blinking?

  22. Hi,

    I bought the super-c 26800 and when I try to charge a MacBook Pro the laptop keeps going from charging to not charging every 2 seconds. What am I doing wrong? I bought this power bank specifically for charging a MacBook.


  23. Hi, I have the ravpower portable power outlet and the last days I noticed a problem with the charging blue lights.when I charge the battery the lights are turned on all the time , all of them (five).also when I use the battery to charge my phone, even though my phone is charging I cannot see any of the lights and I have not any indication of how much battery I have.

    1. If all the lights are flashing during recharging, it is not normal. Could you please change to another wall plug and try again.
      Please note that when using the portable charger to recharge your phone, the light will only turn on for a few seconds at the moment of connecting. It is normal for the lights to then switch off. If you click the power button, the lights will briefly flash to indicate how much power remains.

  24. Hi, I used also another plug and the same problem occurs. I know that the lights will switch off when I charge the phone but the problem is that even when I plug a phone the lights are not switched on. I had to push the power button to see all them lighting up. Also ,all of them are light up when i push the button which means I never see the remaining battery.

  25. Hi, I posted this a few days ago with no reply, I’m not sure if it was missed?

    I bought the super-c 26800 and when I try to charge a MacBook Pro the laptop keeps going from charging to not charging every 2 seconds. What am I doing wrong? I bought this power bank specifically for charging a MacBook.


    1. Hi Matthew,
      Sorry for the late reply. If this keeps happening, there is definitely a problem and we probably need to test this product. Could you please email support@ravpower.com so they can organize a replacement product for you as well as a way to send in this one.

  26. What can I do if my RavPower is fully charged and when I plug something into it there will be ONE blinking light and not charge anything?

    1. If there is just one light blinking I Would assume it has 25% power, no? Hmmm well there are several possible things to consider. Would you mind providing us more details so we can better assess the situation.

  27. Hello,
    I purchased a RP-PB060 powerbank on 2/25 and unfortunately I haven’t been able to use it so far. I have tried to charge it overnight a few times and for over 24h at least a couple of times. Symptom is always the same. The 4th blue light never lights up completely (keeps flashing). Anyway, it should still be able to charge my mobile phone as it is 75% full, but it is not able to. Pressing the ON button does not work at all. Tried to long press it for 30s+ and nothing happens. Can you please help me? Is there a way to fully reset the powerbank? Should I charge it for an even longer period of time (48h or more)? Thanks.

    1. Hi Devanir,
      Seems to be a growing trend if anyone reads all the comments in this article but the product support team think its best you email them to resolve the issue ( I sent them a screenshot of your comment). Their email is support@ravpower.com. They will do their best to help resolve the issue as soon as possible.

      1. Thanks for the quick answer! I did some research and found out that switching cables and even chargers worked for a few people. I used yet another charger which I had left aside for a few years. The powerbank was able to fully charge overnight and it is now working fine. I will report again if there are any new issues. Thanks again!

          1. Spoke too soon. I could use the powerbank only once and could never succeed to charge it again no matter which charger or cable I use. Hope that the support team will be able to sort it out.

          2. I did yet another test: I was able to fully charge the powerbank for a second time after waiting for a couple of days. After that, I let it drain completely by charging my phone for an extended period of time. I thought that this might somehow reset the recharging algorithm. After this I was able to use the powerbank successfully – been able to charge and use it for at least 5-10 times so far. I will update this thread if something goes wrong again.

  28. I’m trying to use a Ravpower 16750 portable charger to power a led light strip (http://www.brizled.com/product/28.html). The lights work fine for about 60 seconds, and then power shuts off. If I press the button on the battery pack again, the power returns. Any help?

  29. I can’t wait for my new ravpower pack to arrive (20,000mah) my quotation is should I drain it all the way down before charging it to 100% to get the best of my cycles or is there a better option?

  30. hi, just recently bought a 20100mah ravpower with quick charge 3.0 powerbank. it is supposed to charge in 4.5 hrs using a type c cable plugged in to its type c input which supports 5v@3A. But to my disappointment, it is already morning, and it just managed to charge it halfway with two lights lit. i am using a tronsmart qc 3.0 wall adapter and a samsung galaxy note 8 type c cable that came with it. Can you tell me what to do? is it the cable? Does it mean I HAVE TO BUY ANOTHER SPECIAL TYPE C CABLE just to charge this thing as fast as it should? I thought all type c to usb cables support 5V @ 3A charging. Please reply. Thanks.

  31. We purchased the ravpower ace series 22000 model RP-P052 in the UK a week ago and we are now touring the states- hence why we purchased this. However, it doesnt recharge in America through the mains. Can you please advise?

    Sue and Simon

    1. Hi Sue and Simon,
      You will need to purchase a UK to US adapter to get it to work. It’s a bit of a hassle but that’s sadly how it is due to different voltage standards. Sorry for the inconvenience.

  32. Hello,recently i’v bought a RAVPOWER RP-PB058 26800mah usb PD powerbank.i just want to know can this powerbank fast charge iphoneX at a safe voltage/amperage via usbC PD?

  33. Hi. I just recently bought a RAVPower RP-PB403. I have one question which bothers me for a while. The power button on the powerbank won’t break / get stuck easily right? I’ve owned several powerbanks in the past and this was the common isssue I’ve encountered.

    1. It shouldn’t. At least, I haven’t encountered that. We also have a lifetime warranty available so register once you receive the product and you’ll be covered.

  34. I recently bought a RAVPower RP-14PB. I was hoping to use it to run a digital piano as there is a YouTube video of someone using the same model battery bank with the exact same piano. The power supply for the piano is 15V, 4A max. When I plug in the RAVPower set at 16V, the voltage indication on the LCD starts flashing rapidly and then the piano turns off (it only comes on for a fraction of second). What does the rapid flashing voltage indication mean and why is the RAVPower turning itself off?

    1. Hi David,

      So that model is not compatible with a 15V 4A device. The maximum output of it is DC 16V 3.5A. That said, this product works with your piano. I have spoken to the customer support team and they said if you email them at support@ravpower.com, they can help arrange for you to exchange your current power bank with the linked model that works with your piano. Wish you all the best.

  35. Hi! I’ve got a RP-PB059 20100mAh, and it works fine I general. There is one problem however. When I charge my Google Pixel 2 XL (usb-c to usb-c) with it, it’ll charge to 100%, and then the phone will start charging the power bank. This of course leads to a lot of wasted power, which is especially problematic since I’m bikepacking and camping camping in the wild so I rarely get to charge the power bank except for with a solar panel (which as we all know takes a while). Looking forward to hearing back from you!

    1. Hi Marcus,
      Glad you’re enjoying the product. Okay so that particular model has the ability to reverse the flow of charging. You can toggle that on and off by holding down the power button for 5-8 seconds. Try it and you’ll find you’re no longer wasting power.

      1. Yeah I’ve figured that out but that means that I have to sit and guard the phone. Overnight charging becomes impossible for instance. Any way to stop it permanently?

  36. I see both the SD card files and the EHD but do not have the “transfer” option in the drop down list.

    1. We have changed our FileHub app which might be causing you confusion. The “transfer” button has been replaced by the “copy”, “cut”, and “paste” buttons under the tool icon list. You can “cut” or “copy” the file first, then enter the destination folder and then “paste” it.

  37. I am using the RavPower 13000mah (iSmart) to charge a new model MacBook Pro laptop and it’s taking forever to up the battery percentage – 2% in, like, 20-30 minutes. Is this normal? Do I need a higher capacity RavPower bank to do the job? Can you offer any solutions? Thanks.

  38. Hi I have the RAVPower RP-PB-43 20100mah battery the four blue led’s are cycling constantly even when the batter is not plugged in to charge. Why is this? its just gonna discharge my powerbank, is there an issue?

    1. That doesn’t sound normal. Can you please tell me your order ID and email and I will forward it to the appropriate department so we can issue you a replacement power bank.
