Detailed Product Description

Call it what you like –
    A battery, A power bank, A quick charge
    We like to think of it as a lifejacket – something you hope to never use but are so grateful to have when you need it.

    This lithium-polymer battery has 4,000mAh of storage capacity – more than enough to rescue you or a friend in your hour of need. And who doesn’t love a great rescue story?

Designer Notes

We kept things simple and straight-forward when selecting this battery. LED level indicators that are only on when in use, no sliding switches to fail, no flashlight - just 4,000 mAh of stored power to recharge nearly any device you own. Get in the habit of checking the LED levels and simply re-charge when needed. Enjoy!

"While traveling, you're less likely to find a handy outlet or charging port, so you need to carefully meter your device use. But with a battery pack, you can refill your battery on the go. The most reliable batteries I've tried to date are eBags' Lifejacket Quick Charge Battery and the larger Lifeboat model. I would recommend either of these models to anyone. I also love how they are flat, making them easier to fit in bags. The Lifejacket one even fits into just about any pocket. These battery packs have been completely reliable, and quickly and effectively charge my devices."

"Fast charging! Says you can't bring on a commercial plane which i didn't see this mentioned beforehand. That was disappointing."

"It took forever to get charged. There aren't any instructions that came with it so I guessed that after plugging it into the USB port and watching 3 little blue lights chasing each other meant it was charging. That went on for nearly 24 hours and instead of 3 lights at the end there were only 2 blue lights chasing each other. There's no case but it came in a sturdy plastic bag that I'll keep it in while I travel. I'm going to do a practice run with it before I go on vacation and will review it again if it performs poorly. It's very small and lightweight and it's a slippery little devil. It will be lost at the bottom of my purse if I don't keep it in a larger case."
