Customer Ratings & Reviews

Got this just to have. I don't use it all the time, but there are circumstances where it comes in handy. It protects my phone very well, and does live up to the 60% extra charge time. I wish it were thinner, but there's little too be done about that. Regardless, for a battery phone case, it is the thinnest I've seen on the market.

Very sturdy case with back up battery without the bulk. Nice slim profile. Great for professionals on the go with up to 60% extended battery life.

Looks great on the phone and provides just the amount of protection needed without being too bulky. Nice to have a battery that is very safe. Charges my phone from 20% to 80% as expected from the 60% advertised extra charge.

This case is amazing it provides a flexible feeling to a battery case un like others it also has a great grippy fealing and is very durable would recommend to anyone who uses there phones A lot and needs the battery.

I liked the fact that this was a "slimmer" profile case, but I'm not a fan of how you insert the phone into the case and it is difficult to find chargers that fit well

Switched to this case from the life proof with battery and glad I did. This case is much lighter and smaller.

Thus far it works very well - charges about 60% - can keep you going in a pinch.

Works good for the price gives u only 1 full charge it will last u a day

This is a great product with light weight and easy to carry .

Really good help. Save time charging mor often is nice

Got this on sale for 30 bucks, bought 2, and works fine. Phone just slips right in, all one piece case. Phone is slim enough too. Charges to 60%.

I bought this at the last minute, needing a charger for my daughter. The salesman told me it was more expensive than other models, but would provide 100% more power than other models that only had a charge of 60%. Looking at Tech21's website, it seems this is not true. To fully charge this unit took about 8 hours!? Unacceptable. That's what you get when you don't do your research before you buy. I do like the protection it offers as a phone case, so it's okay.

The case is easy to hold and the ceramic battery gives a longer battery lifer per charge.

I love this thing! I got rid of all other chargers. Now I need to buy my wife one too!

Great case. Only reason it didn't get 5 stars was b/c the battery wouldn't charge it enough, I wish they would've added more mAh

Works as expected! Keeps phone charged and ready for use.

I really enjoyed this case but the battery doesn't last as long as I would like.

I was super excited that tech 21 came out with a battery case. I love their products but I'm not sure about this case. I don't like how bulky it feels and I get that it's literally an external battery on the back of your iPhone but it's heavy. I'd rather have my elite case on. Instead I leave it charged and in my purse ready for use when I have no chargers around. This is great for pokemon go though!

This is good if you don't always waste ur battery when your out. Make sure u always charge it with its own charger or it won't fully charge. The one I bought was for a charge up to 60% so I wouldn't only recommend this if u just travel from home to work.

Purchased several Tech21 products before and I am extremely satisfied with this product. Definitely recommend for those who drain their phone battery often.
