Really good extra battery

I got this while it was on sale, but it's actually worth its original price. Really good extra battery. Usually end up using mine for weeks before charging.

I love this thing. I feel like I never get as many charges as I should but just close enough. Charging it takes a while for me at least but it is a great backup. It is a bit heavy but that's just what to expect with a battery with this much juice. Definitely pick one up for the value

I love this thing, it doesn't over heat, the power output is very similar to the original battery, and it lasts for ever! (not really, but it gives me double the original battery life easy!).
The only down turn to it (other than the obvious increase in form factor) is the back cover, while it clips on very nicely, I still think they could have had the bottom of the cover a bit more contoured at the end.

I gave this battery to my nephew,as a birthday present because his cell phone was frequently running out of power.  We haven't had that problem since!  It works great as a replacement and doubles as a backup, daily.

The speed with which it was delivered was also really impressive.

So far I am really pleased with the battery. I get about two and a half hours with this battery. The price is really good.

extra battery is much needed for my gopro 4, these two work well and I think it last about the same as gopro one, now I just have to wait to see how long it will keep this good condition.

I bought these as backups. It is great to always have an extra battery that is charged and ready to use. No more waiting around for a battery to charge because the extra is there and ready to go. I highly recommend to all.

Great extra battery! I owned the predecessor to this case and it protected my phone and provided plenty of battery for me until I dropped it for the seventh time. For the price its a great value.

An extra battery is great to have!  Wall charger works great with the wall charger!

This battery charges quickly and holds a charge much longer than the after market batteries I have tried. It is always good to have a spare or two wehn you are on location somewhere and don't want to miss shots because the battery died. Especially important for video.

good battery for spare to have around when you need that extra battery when your out in the field away from charging

Im very happy with this extra battery. It takes about 2-3 hours to fully charge & then it charges my iPhone 2.5 times very fast.

Having the extra battery really helps. I am getting about 15-18 minutes out of each battery. I am using the drone to take real estate photos and it works great, really can't believe how good it is for the money!

Glad to have this battery - the one that came with the camera is getting a little short on life, and I'm now using the original as a backup.  This battery works great, and I've had it in the camera for quite a while now and still no recharge has been needed.  So I would say I'm happy as a clam with it.

Paid very little for this extra battery& its been a lifesaver. The 4/5 day wait delay was worth the $45/50 savings.  :)

Really good battery that charges through the selectable voltage "laptop" port and the 2.1A USB port at the same time. This is a really handy feature for me, as I use the battery to power some custom circuitry AND charge my tablet at the same time. I'll probably buy another one
