Power Bank Maintenance: What To Do When A Power Bank Stops Working

Power banks lack the delicate screens of smartphones and flimsiness of folded laptops, so it’s easy to forget they’re vulnerable too; our guide to power bank maintenance and troubleshooting can help you put a finger on whether you’re in a repair or replacement-type situation.

Why Do Power Banks Stop Working?
Why Did My Portable Charger Stop Working Power Bank Maintenance

  • Battery Age: Battery technology is improving all the time, but even the latest and greatest are still mortal, especially batteries that are frequently and irregularly charged and discharged (like power banks and smartphone batteries). If you’ve had your power bank more than two or three years and use it often, you may’ve simply worn your battery out.
  • Cable/Socket Issues: Not all power bank maintenance issues are battery problems. If either the AC power cord (if applicable), USB cable or USB socket is damaged, you may have difficulty interfacing with your device. Fortunately, a USB cable at least is much cheaper to replace than an entire power bank.
  • Weather/Temperature Damage: Batteries are sensitive to differences in ambient temperature. In this interest of holding your hand through all kinds of weather, we’ve prepared guides for using our power banks in both extreme heat and extreme cold. (Look for our guide on power bank safety in extremely nondescript weather, publication TBD.)
  • Owner Abuse: This is a no-judgment zone. So you can be honest. Have you dropped your power bank a couple of times over the years? Spill anything on it? Piled a bunch of stuff on it? These look like toothmarks here on the cord, but we’ll assume they’re from the cat. If you’re using your bank on the go, it’s likely to have absorbed a beating—eventually this takes a toll on performance. Sometimes “power bank maintenance” is really just a commitment to do better next time.
  • Manufacturing Defects: If your power bank is basically new (and you haven’t buried it in a snowbank or chucked it against the wall) and it doesn’t work properly, you may have a manufacturing defect. If you bought the bank in-store, we’d recommend returning it along with your receipt; if online, contact the retailer. (If it’s one of ours, shoot us an email at support@ravpower.com with your order ID and we’ll take care of it!)

 

Troubleshooting Your Power Bank

Troubleshooting a Broken Power Bank Damaged Charger How To Fix A Charger

Now that you know a little bit about power bank maintenance and the most common ways they fail, we can explore how to narrow down the issue.

  • Does the device you’re trying to charge work? In a scientific experiment, researchers will establish a “control” group to serve as a baseline to compare their results to. If you’re mainly using your power bank to charge one device, try it with a different one. This will help you determine whether the problem is with the bank itself and not the other device. Make sure you’ve established that the phone or other device you’re using for this test works properly.
  • Double-check your cables: Likewise, try your USB cable with another pair of devices to make sure it’s working right. Cable quality matters!
  • How are your sockets? The USB socket on your power bank should be stable—if it wiggles, or you have difficulty pushing cables into it, it’s likely been damaged. Fortunately, USB sockets are a fairly cheap fix in most scenarios.
  • Contact customer service: If your device is relatively new, you may still be covered by a manufacturer’s power bank maintenance warranty. If the manufacturer determines you’ve been using your device in a reasonable fashion, and you are still within the warranty period, they will repair, refurbish or replace your unit. We offer a standard 18 months on all products. You can add an extra 12 months on-top in less than a minute over at our homepage.

 

Power Bank Maintenance: Looking After Your Power Bank

How To Avoid Damaging Electronics Minimize Over Discharge Damage PCBA Damage Battery Damage Broken USB Ports

 As every old-timer (plus ‘80s hair metal legends Cinderella) loves to say, you don’t know what you’ve got till its gone. Every power bank stops working eventually, but there’s a lot you can do to put off that fateful day. Try these simple power bank maintenance techniques:

  • If the power bank is used infrequently or hasn’t been used for a long time, we recommend fully charging it every three months. This will prevent battery damage resulting from over-discharge of the product.
  • The recommended temperature range for power banks in use is 0°–45°C (32°–113°F), while the safe ambient temperature for devices in storage is -10°–45°C (14°–113°F). Make sure you store your tech in a dry and ventilated space!
  • Avoid dropping, knocking or hitting the power bank! Physical shocks can cause PCBA components and batteries to be damaged.
  • When you’re not charging a device from your power bank, we suggest unplugging the cable from the USB socket. Leaving it plugged in risks damaging the inside of the port.

  1. Hello

    My Ravpower Power bank has stopped working due to age

    When I purchase another one, can I send my present one to you for proper disposal

  2. I just bought the ravpower pb058 26800mAh. When i charge my galaxy note 9 with the samsung charger it took 41 minute from 60 to 100. I expect with the ravpower it charges faster or at least similar to samsung charger. But when i use the ravpower with the type c to type c cable it took almost an hour from 60 to 100. Can you explain to me about my problem. Thanks

      1. Okayy I got some problem, why my powerbank suddenly stopped charging? I have to press the button again to start charging again. Thanks

        1. We’re sorry to hear that Domenico. Here’s two possible solutions, please try them and let us know if the problem is resolved:
          1. The connecting cable may be loose which can cause the power bank to suddenly stop charging. We advise to unplug the cable then press the button to reactivate the power bank.
          2. If this still doesn’t work, we advise to try with a different cable. Sometimes its a cable problem due to wear and tear or old age. It’s always important to pay attention to USB cable quality as we previously covered on the blog.
          For reference, we did write a power bank maintenance and troubleshooting guide which might have some information to benefit you. Hope all this helps.

  3. My Rav Power Deluxe RP – PB19 shows fully charged and will start charging my phone then after a few minutes will stop. If I press the button to try to power it back into charge it will not charge and just on blue light starts to blink. If I unplug everything and put the power bank back on the charger and then reconnect it to my phone it starts the cycle all over again but it will not charge any longer. The unit is about 2 or 3 years old and not heavy used but I keep it charged up every few months.

  4. Uhmmm,my ravpower bank that is i think 10400 MAh is broken because even though i use it around 5 times a week,and charge it to full,right now i just tried my powerbank and it wont work,i tried different cords,different phones,and even charged it again even though it wad already fully charged before i unplugged it,when i charge it now it stays at the first dot but it does not blink like it used to i just got it in less than 3 months ago and i never dropped or broke part of it pls fix

  5. Hello, I have a Rav model RP-PB067 26800man portable charger that has only been used possibly twice. It shows a full charge but will not charge an Android phone or a kindle fire. The cables work fine with an AD charger . Nothing happens when I plug it in either device except if all plugged up in the kindle fire and push the side button on the charger, the blue lights on the rav flashes and the kindle will chime and most of the time that is it with no charging at all. On occasion, the charging symbol will pop up for a few seconds and then goes off and again, nothing happens. The RAV lights will flash but it will not charge anything. As I said, this has not been actually used more than two maybe three short times and was kept charged and in my bag ready to use. Very frustrating to finally need it and it doesn’t work. Please advise. Thank you

  6. my Ravpower 22000 power bank only shows one light flashing while charging and does not go past that. It doesn’t matter what source I use.

  7. Hi I have a ravpower bank that is about 6 months old. The charging light sequence has changed where all 4 lights flash sequentially but never show it has fully charged. When I plug my phone in, it charges my phone as normal. Should I continue using it?

    1. Hi Marc

      We recommend that you stop using your powerbank if it shows cracks, smoke or other abnormalities. If the powerbank is charging as normal then there should be no reason to worry.

      If you have any questions or want to discuss this matter further, please contact support@ravpower.com

    1. Hi Yrvin

      Thanks for getting in touch! The standard powerbank drop test is 1.2m. We suggest that if you have dropped it from a height above that, that you replace your powerbank. Moreover, if the power bank cracks, starts smoking or has any other abnormalities, please stop using it immediately.

  8. I have the WD03 Travel Router/Power bank. The router stopped broadcasting even when fully charged or plugged in. For the past 3 weeks, it would be on and connect, but would automatically disconnect from the Wi-Fi after a period of time between approximately 10-45 minutes. When I turn it on the four white light turn on in order, then the green Wi-Fi light. Immediately after the green light turns on all the lights turn off except for the bottom white LED that starts blinking.

    What’s going on and how do I fix this. Currently deployed, so I’d like to not have to go for 2 weeks without it while it ships home and a new one comes in.

    1. Hi Michael

      Thanks for getting in touch, and sorry to hear that you’re having issues. We will need more information to specifically diagnose the issue with your device – to do this, please contact support@ravpower.com

      In the meantime, please remember that the WD03 Travel Router is limited by size and power consumption. Travel routers have a weaker signal than a normal router.

  9. My Rav Power 22000mAH shows fully charged and will start charging my phone then after a few minutes will stop. If I press the button to try to power it back into charge it will not charge and just on blue light starts to blink. If I unplug everything and put the power bank back on the charger and then reconnect it to my phone it starts the cycle all over again but it will not charge any longer. The unit is about 2 or 3 years old and not heavy used but I keep it charged up every few months.

  10. I bought a rav power bank from Amazon 22000mAh on the 11 April 2018. Yesterday it stopped working. The item does not charge itself and does not change anything as a result. It is within the warranty period and hope to get a replacement.

  11. None applied to my situation. It was working fine. It ran low of power so I plugged it in to recharge it and it never charged. It just keeps blinking one light and it doesn’t go out like it used to when not plugged into anything. It was not your brand. I only used it maybe 10 times total. I really liked it too. It was so handy. I have had it to long to return it though.

  12. hi, i’ve purschased a 4X battery charger for cr123a and i’m wondering why the 4 lights are blinking red. they’ve been on charge for few hours now and still blinking. In the owner manual there is no information about ”red blinking ”.
