Very poor battery life and output

We love these batteries

so my battery gets drained within a few hours of working each day depending on what that day consists of and what app I am using and how

Nice battery in a rugged case with a bonus flashlight built in

Great battery backup.

Worst backup battery I have owned.

it works but after chargine 2 iphones it drains the battery to only have 2 bars left.

It's a little heavy, but that's the trade-off for a convenient portable battery!

Really nice backup battery can charge a cellphone about 2-3 times a fit bit for about 2 months

Great backup battery.

This external battery is awesome

This resilient portable battery has everything one would look for in a product

Mixed comments about that so not as useful as my other battery

This battery holds A LOT of power!It will take time to charge if you run it down a lot, but it's still worth it

The battery itself is sturdy

I noticed that the battery got incredibly hot while charging his phone.

The battery still works fine

but I soon realized I carry it everyday because my battery sucked so definitely worth it

If you need something to throw in a bag and get dropped without any concerns this battery is a champ.

But the devices' batteries are more capable than they used to be.

Works as described, great outdoor battery

Best external battery I've ever had, anything that is sturdy enough to double as a club is ok in my book.

This external battery worked as advertised for about 6 months but will no longer take a charge and is dead

I'm completely satisfied with my UNIFUN 10400mAh Waterproof External Battery.

So, I wrote a nice review and loved it til this morning when it suddenly burst into flames (while charging), and caused damage to the chair it was charging on, as well as the rug and carpet

This product worked exactly as I had hoped for

Didn't last long and now it won t charge
