What it is and who it suits

This GENSROCK CK25100 power bank delivers 10000mAh capacity with 22.5W Power Delivery charging. An integrated LED display shows the exact remaining percentage from 1% to 100%. It suits commuters and travellers who want precise capacity read-outs and fast top-ups for phones or small USB devices.

Who should look elsewhere

Buyers needing more than 10000mAh for multi-day trips should look elsewhere. Users who require wireless charging or laptop-level power above 22.5W will not find those features here. The two-port layout also limits simultaneous charging to two devices only.

Behaviour under sustained load

The 90% high conversion rate helps maintain efficient output during extended charging sessions. FCC, CE, UN38.3, ROHS and UL certifications confirm protection against overheating and short circuits during continuous use. Dual ports share the total power budget when both are active.

Questions about this item

What cable do I need to use the 22.5W USB-C port on the CK25100?

Use a USB-C to USB-C cable that supports Power Delivery, or a USB-C to Lightning cable for iPhone 12 through 17 models, to reach the 22.5W fast-charge rate.

Will the CK25100 charge my older phone that only has a USB-A port?

Yes, the built-in 5V/3A USB-A port works with legacy cables and devices, so older phones charge at standard speed while the USB-C port handles newer gear.

How do I confirm the CK25100 is delivering 22.5W after I plug it in?

The LED display shows the exact remaining percentage from 1% to 100%; watch the phone's own charging indicator jump from 0% toward 55% in the first 30 minutes to verify fast-charge performance.
