Battery Case for Samsung Galaxy S21 Plus, 6000mAh Extended Battery Charger Case for Samsung Galaxy S21+ Plus 5G [6.7"] Portable External Backup Battery Charging Case Pack, Add 100+% Extra Juice, Black

It's very sturdy and hefty I feel like it can protect my phone and the big battery inside it. It also has a lil kick stand which i hasn't realised but is a nice touch. Speaking of the battery it holds a good amount of charge and really extends the life of the phone, and in that regard it works great! It even has a usb port on the side so you can use it as a power bank for other things which is neat!However I do have two large gripes which mean it is a 3 star review from me. It claims you can charge the case by plugging it in and charge the phone from the case at the same time. Sadly this doesn't actually work, it only charges the phone for about 15 seconds before cutting off and needing the button on the back to be pressed again to keep charging the phone. This isn't a world ending issue though as the case charges quite fast and when it isnt plugged in charges the phone continuously with good performance, however it is pretty annoying.The other problem is honestly also kinda just annoying more than a deal breaker, but if you plug a cable from your computer to the case it will charge up the case as exoected, however there doesn't seem to be working data pass through functionality, so if you want to access files on your phone you have to take it out and plug it in directly

My 1st case that was sent didn't work but after a few emails a new one was sent nd works great, it's chunkier than i originally thought it would be and heavy but I really like it, I now don't need to worry about my battery going on trips etc.

Very heavy as expected from the reviews but it’s only to charge it

Product will not work with phone - wrong size. Could not find way to contact seller, wish to return for refund. Still in presentation box

Good product helps keep my phone charged all day defo buy again if it broke

Not fit with HONOR 10

One star only because it arrived, cannot fit my phone in it, it's correct cover according to plastic case it arrived in
