Sitong Battery Case for Samsung Galaxy S21 Ultra 5G, 5000mAh Rechargeable Extended Battery Charging Charger Case, Add 100% Extra Juice, Not for S21 or S21+ (6.8 inch) Black

As of using this product for about a week I'm pretty satisfied.

**** Aug 22, 2024 update ****As per Amazon, "ignore seller's advice and just return it"Seller wouldn't issue a refund unless review taken downNot a good idea to strong-arm buyers!Case will charge your phone sometimes to 100%.Example, your phone is at 40%, your battery case @ 100%.Your phone will charge to 100%, and your battery case is at ZERO.Weird quirk, to activate charge to phone, ONE click on button starts charge. TWO clicks to stopShould be other way around to prevent accidental activation.

I think I was missing this the whole time . I'm always on my feet at work so I can't really charge my phone since I work in management at a retail store . So this case helps me get extra battery life quick and whenever I need it. Keeps my phone charged if I need it to. I can't really take a picture of it in use because I'm using the phone to write this review hahaha. It's not too heavy or bulky for me. I think it's also pretty durable looking materials wise. Haven't dropped it yet though so totally not sure tbh. Thought this case would be more expensive , so this was a good product overall

The battery life is amazing, easy to fit and comes with a stand.When the battery case is connected up to my phone, it feels sturdy and battery life is into day 2, before hand, not anywhere near that 😀

Bought this as i work on sites with no power. So wasnt fussed about weight as i leave my phone on my tool box.Nice soft case to touch however it took me forever to get the phone in. No access to usb pen. Might have to drill a hole on the case for access. Kick stand is flimsy and feels like it could come off easily. Will see how i get on with it this week.

Overall I'm happy with my purchase. I used it on a long journey and it managed to keep my phone powered well beyond its battery life.It offers decent protection too, I've dropped it on concrete and gravel and my phones remained unmarked.

It doesn’t hold enough charge to recharge my phone.

Things I like about this case - comfortable to hold, not too thick and I can actually still get contactless payments to go through, even with the case on. It also allows me to use my phone all day for sat nav and taking photos and videos without needing to plug it in.Things I dislike - very slow charging. Best I have managed when charging both together on overnight charging is 100% battery charge and 50% phone charge. Even with the brand new Samsung charger which came with my husband's new phone last week. The devices were plugged in for 9 hours to achieve this. Also this case only charges my phone to 70% from 5% on a full charge.Previous battery cases we've had don't allow contactless payments, buy do charge much faster and all a full phone charging from the battery case.
