World's Slimmest Detachable Battery Case | mybumper

Frequently Asked Questions



Mybumper won’t charge my phone what do I do?

First, make sure all 3 lights (green, yellow and red) turn on after charging your battery pack and double tapping the power button on the back. This means the battery pack is at full capacity.

The most common mistake is not double tapping the power button to activate the charge. To do so plug the lightning cable from the battery pack into the bottom of your iPhone 6 and then double tap the power button. Viola, JUICE!

If this does not work send an email to and we will make sure to help you out asap.

How many charges can I get out of mybumper’s battery pack?

You can charge the battery pack 3000 times. I know wild right.

How many extra hours of juice does a mybumper give my iPhone?

On average it’s double the charge so assume another 10 hours unless you are abusing your phone then expect to get double what you usually get from your iPhone.

Does mybumper ship to countries outside of the USA?

mybumper ships everywhere in the world with FREE shipping across every state in the USA.

Can I charge my phone and battery at the same time?

100% you can. Just plug the lightning cable from your mybumper battery pack into your phone and double tap the power button like you are using the extra charge. Then using your micro usb cable, plug that into the battery pack. This will prioritize your phone to charge to 100% and when it’s done it will charge the battery pack to 100%.

Best to do at night beside the bed that way you hit the sack and wake up with both the extra battery and the phone fully juiced.
