I have been using this battery case for my device for a over a week now, and I am thoroughly impressed with its performance.The case itself is well-made and sturdy, with a sleek design that fits perfectly in my hand. The battery life is excellent, providing an additional aprox. 20 hours of use on a single charge depends how you using you phone.This has been a game-changer for me, as I no longer have to worry about running out of juice during long days of use especially when i am on journey.One of the standout features of this battery case is its fast charging capabilities.

The case is made of a durable material that provides excellent protection against everyday wear and tear.This has given me peace of mind, knowing that my device is well-protected and secure.Overall, I am very pleased with this battery case and would highly recommend it to anyone looking for a reliable and high-quality charging solution.5*

Very useful for long travel. Good price as well as phoe protection.

The case is good. Quite chunky but that is to be expected as it is a charging Case. Easy to remove and apply, works well.The only thing that annoys me is that it doesn't fully charge my phone before running out of battery itself. It will usually get my phone to around 80% from an initial 10% meaning it only gives me an extra 70% battery. Still use the case but I don't rely on it on its own if I know I'm going to need to recharge my phone fully, I always bring an extra power bank with me.

Bought it and it worked well - slightly slow charging with some cables, but found one it works well with, and always charges before the phone unless you switch it off.But only lasted 3 months then stopped working for no reason.Disappointed but now this has been sorted out and very very happy to keep using it.I find a single charge (usually from a spval charger) only takeaway a couple of hours and can last a full day of travel without worry. The light helps say how full or empty it is.

Great

The fit for the smartphone is good and would indicate a permanent stay on the device.Unfortunately, the charging time using the charger for the power bank and the phone together is very long.Power bank 100-120min 0-100%, and only then the phone battery starts to charge OVER 8 HOURS !! It takes 120 min directly from the charger.Due to the necessity to dismantle it frequently, I do not predict a long life for a USB port.

This is the best product ever I have got on Amazon. I am so pleased to have chosen this charger case for my Samsung S21. As I travel a lot I have been looking for something like this for ages and finally I have found the one worth it. Battery last almost a week, it is super easy to charge and quite stylish. Highly recommended it

2 months old and already stop working.
