Baseus H1 Lite Fast Charging Power Bank with Digital Display 20000mAh 100W Cosmic Black

I had purchase this product couple of months back and now its not working pls help me in this matter.thanks.

Excellent speed of charging. Approved for Air travel. Took it on a trip from US to Europe. Handled charging my Switch 2 and OnePlus Open phone which both have almost 5,000 mAh batteries. Could charge both of them from 0 to full and have some left over. After doing extensive research before I bought it, I learned it's one of the most efficient powerbanks. It's very slim so it's easy to slide into certain pockets and not add to the bulk. It isn't very heavy, just the right weight. The screen is easy to read. It comes with a 100W USB C cable so you're good there. You can't go wrong buying this power bank. It's probably the best 20,000mAh powerbank out there in terms of performance, design and price in early 2026.

on product on backside showing it's 5000 mah

Much better than other brands as far as thickness, how many ports it has, and how they’re laid out. Display is easy to read and looks good. It can hold enough charge to easily charge every single device I have about twice (iPad, iPhone, Android Gaming Device, etc) Fits in my messenger bag like they were made to go together. Most other batteries are thick and tall, hard to fit in narrow pockets. Not so with Baseus here. Charges a tad slower, but also puts out higher wattages more consistently than other batteries I’ve used in the sub $100 price range.

This slim 100W power bank has been extremely useful for travel and long workdays. It’s surprisingly flat and easy to carry in a laptop bag, yet powerful enough to fast-charge my laptop and phone without any issues. The 20000mAh capacity easily lasts through meetings and flights, and the real-time display makes it simple to track remaining power. Charging feels fast and stable, and the build quality is solid. Overall, it’s a reliable, well-designed option for anyone who needs serious portable power on the go.
