Power outputs are as specified, with the power bank capable of generating 45W of power using just one USB-C port. It can be recharged at 40W, which means it can go from 0 to 40% in about an hour using a 40W+ charger.

The integrated cable is also durable and seems to last the life of the power bank. The LCD screen provides an overview of the charging capacity, much better than the few small LEDs that some power banks still use.
The LCD screen is clear and easy to read.

Everything is encased in a sturdy, durable plastic shell, with a grip pattern on the underside. I’ve been testing this power bank for a few weeks now, throwing it in my pocket or backpack, and I can tell you now, this one doesn’t expect to get damaged!
As for safety, I pushed this power bank hard under various loads and had no issues with heat or throttled output. I even had it charge my devices while in my pocket — a pretty high-temperature test for many power banks — and it didn’t have any problems.
ZDNET Buying Tips
the Cuktech 20,000mAh power bank is a great power bank and comes at a great price. I don’t look at the retail price of things before reviewing them, and to be honest, I expected this to be around $60.
That’s not true. Normally retailing for $30, this product represents excellent value for the money, but there’s currently a 30% off coupon on Amazon, bringing the price down to an unbeatable $21 failure.
This Cuktech device is perfect for people with smartphones, tablets, and even smaller laptops. You can spend two or three times more to get a power bank with similar specifications, but you won’t get anything extra.
