Sethruki Portable Charger 20000mAh, Smallest & Lightest Dual USB External Battery,Ultra-Compact Fast-Charging-Technology Power Bank Compatible for iPhone,Samsung Galaxy and More

This is OK but takes a long time charging but also charges my phone fully about 2 almost 3 uses.

This works well and charges my USB devices fast. It looks nice with its black finish and the rounded angles make it easy to carry. The USB type C interface also is convenient to charge. You can use micro USB, USB type-C and lightning chargers so you're never left without any options to top it up. Very convenient when you're on the go. This is especially useful when traveling. I do a quick top up when I'm at my friends place or in his car. As we both have different cables I don't have to worry about swapping cables. Just plug and go. but as it hold so much power it's worth it. Great for the power user who's always on the phone.The only drawback is the weight. This is fairly hefty. It's not that large though. Though with it packing so much power I really don't mind. It doesn't fit that well in my jeans pocket so I just have this tucked in my bag.

It was good in the begining charging very well, but last too days starting to lose the inside power , going empty so fast can charge my phone even one time

I have used this portable charger for a little over a week now. I must say I am very impressed! I travel a lot and use my cellphone for everything. Having this charger has saved me on my adventures. It charges my cellphone to 100% while still using my phone while using gps, searching the internet and taking photos and videos of my adventures. I also charged my iPad Pro and cellphone at the same time. This portable charger still has charge left after charging both of these to 100%! I definitely recommend this to others.

Ive been using it as my daily driver now for the past week and a half or so and I love it. My day usually starts around 6:30am and I dont get home until around 7:00pm and this bad boy lasts me all day. Very quick charge and ai can even charge my ipad pro on it. If you’re a student like me this is the perfect battery to just throw in your bag and not have to worry about your battery life on any of your devices.

Didn’t charge quickly ( Took more than 24 hours ) and didn’t stay charged very long when traveling. In addition, the very tiny 4 dots that show how much charge is left, is very hard to read or even find! Very disappointed in this product, especially compared to my previous charger

Works well with my iPhone XS, very useful when traveling. My phone gets fully charged in a very short time. Love the very simple but modern, minimalist design as well, a little heavy but I really don’t mind. I also use it at home, it becomes very convenient especially when using your phone while you are laying on bed.

I have been pleased with this power bank. It has a good amount of charging capability and seems to be of good quality. The price for it is reasonable. Only time will tell if it holds up under many charges/discharges but I have no reason to believe it will give me any problems. I would purchase another if needed.
