    1. Hi Rich,
      Here is how to calculate it:
      • (mAh)/1000 x (V) = (Wh)
      • 27000/1000 x 3.7 = 99.9 Wh

      Take the Wh and multiply it by the DC to AC conversion rate which is around 75% (though it can be higher)
      • 99.9 x 75% = 74.925 Wh

      Then divide this figure by the total watts
      74.925 / 60 Watts = 1.248 Hours

      A 27000mAh power bank will power your 100 volt light at most for almost an hour and a quarter.

      We hope this helps.

        1. Hi Klusner,
          It’s a good question.
          • 3.7 is the typical nominal voltage of a lithium-ion cell. Nearly all our power banks use lithium-ion while only a few use lithium-polymer batteries. More info here.
          • Power bank batteries are measured in milliampere hours (mAh). This is 1000th of an ampere hour (Ah). The formula requires the amphere hours hence why we divide by 1000.
          Hope that helps! 🙂

  1. Hi,

    I have just bought the Solar Charger RP-PC005 with 3 USB connections but when I try to charge my iphone it says this product is not supported, do you know how I can fix this?

  2. There is NO INFO on how to “use the raypower ace series12000mAh External Battery Pack” and every youtube video is different what what I bought. I have two Smart holes on the bottom and there is a micro on the side. NOTHING is the same as this. HOW can I learn how this works??? I need a video that is exactly like what I purchased or I can’t understand it. I tried 10 others. PLEASE help me.

  3. Does the RP-WD03 have MAC filtering capabilities onboard? If I wanted limit access to 4 specific computers to this wireless hub, can I add those MAC addresses into this router and block all other incoming signals?

    1. Hi Jilly,
      We currently do not ship to South Africa. You may look to alternative means like ordering from Amazon.com and using a shipping company to help deliver it. Sorry for the inconvenience.

  4. RP-IM005 model for the RAVPower iPhone external memory 64gb stick iplugmate, I received this today in Amazon and I am having trouble when using iPlugmate to transfer my songs in Apple Music, when I go to music in the app it only shows 1 song that is not in my library. Please I need a fix

              1. Hi Tuoyun,
                We’ve recently had some trouble with our listings on Amazon with a number of them being blocked. As a result, the camera battery is not available until after we resolve our issue with Amazon. Apologies for the inconvenience.

  5. Look for a power bank to power a dash cam whilst in Parking Mode. It will be used in a hot country.
    What do you advise?

    1. Can the dash cam be powered with a standard USB input or does it need USB-C? Just to be safe, this is your best bet in terms of a reliable power bank. LINK.
      Just note, its best to keep a power bank in a cool place so hopefully you don’t run into any issues using it in a hot car.

  6. Can you tell me if my model RP-PB41 26000/mAh can be taken with me on a commercial flight? I need to know asap.

  7. The negative terminal for my car battery jump pack broke in half. Any way I can get a new one? Or do I have to buy another jump pack?

  8. I plan on taking a road trip and need an external battery/charger for my surface pro 4. I understand the surface pro is a 65 watt device. What charger/battery do you suggest and how long would it keep the surface pro running?

  9. My Ravpower power bank Turbo+ Series 20100mAh will only charge my iPhoneX while the iPhone’s screen is on. This is either when it’s unlocked or when awake but locked. When the screen goes black, the charging stops. This happens from both the Quick Charge USB port and the iSmart 2.4A USB port. This happens with both the original apple USB cord and third-party USB cords.

    Otherwise, the power brick seems to function as it should. It charges correctly, shows power status correctly, and charges a 2017 macbok pro through usb-c correctly.

    What is the issue with the iPhone?


  10. Where can I buy a replacement charger adaptor for my 27000mAh Powerstation RP-PB055 please? Mine snapped after a couple of months. Amazon reseller unable to supply.


      1. Thanks for the reply. Sunvalley have told me they can’t provide a replacement but will provide a partial refund to purchase a compatible charger. But I’m struggling to find suitable adapter with the correct rating and thin connector. Can you advise what I should get? Thanks.

  11. I’m getting error message trying to copy iPad pictures of onto the ravpower’s sd card. It says it can’t download picture information. Any solution?
