Impulse 10,000mAh External Battery for Mobile Devices

mostly bad reviews..hopefully you get one that doesnt lose its charge

Those "number of full charges" figures are assuming 100% efficiency, which doesn't exist in this world. When charging a battery, you're lucky if you get 70% of the input energy back.

Note that while practically every phone or mobile device has a USB connector or for charging and data transfer, not all such devices will actually CHARGE when connected to a 5-volt power source such as this. Many plug-in chargers deliver more than 5v to their devices. That's why specific compatible devices are listed along with other devices "with 5V input". If your device actually charges, not just lights up, when connected to a computer's USB port, it should charge from this battery. If your plug-in charger delivers more than 5v to your device, this battery might still charge it more slowly, or not at all.

it's an amazing price drop. looks like something that's worth investing in.

good price. mulling if i should get it or not.

Great low price, gotta say this is probably the lowest I've seen it.

Just bought two. FYI it has TWO USB inputs to charge two devices simultaneously.

This would be so worthwhile if spending a length of time in the back-country. So many phones take great pictures & videos, but can really drain your battery, too.

great price, thsnks for finding

wow this is a great deal. thanks for sharing

Super price! I like that you have a choice of Black or White on this device. Thanks for sharing this Great Deal! :)
