SitongBattery Case for Samsung Galaxy S21 FE 5G, 5000mAh Rechargeable Extended Battery Charging Charger Case, Add 100% Extra Juice, Not Compatible with Galaxy S21 (6.4 inch) Black

This product saved me, it's very good!the battery works very well and charges the phone very quickly

This battery case has significantly improved the battery life of my Galaxy S21 FE. It doubles the battery life, which is essential for long days out. The integrated power switch is very convenient, and the LED indicator helps me keep track of the charge level. Despite the added bulk, the case is slim enough to handle comfortably and provides great protection against bumps and scratches. Perfect for travel and everyday use.

Out of the box it looks like it would be difficult to fit but pushes in great and fits the phone snugly. The matt black doesn't seem to scratch easily and the little stand on the back is great. It does make the phone a noticeable amount heavier but that's to he expected with a battery bank. Been using this for a week now and I'm now not charging every night on a low usage day or worrying about running out.

This product is incredible good quality i can charge my mobile twice amd also can share with other with usb port bit expensive but as fit to mobile i think it worthy

I have used this for more than a week now and it is great for my Samsung, it fits nice and isn’t to heavy or bulky.Battery life seams good and gives me plenty of charge to get through the day.
