45W USB-C fast charging

The JUOVI J2621 is a 20000mAh lithium-polymer power bank that delivers up to 45W Power Delivery through two USB-C ports. Two additional USB-A ports support Quick Charge for legacy devices. A digital LED display shows remaining capacity from 0 to 100 percent. The 74Wh rating complies with airline carry-on limits.

Travellers and multi-device users.

Four simultaneous outputs suit travellers, business users and students who charge phones, tablets and accessories together. The 45W ceiling covers most ultraportables but cannot drive larger laptops that need 65W or 90W. Buyers who must fast-charge such machines should look at higher-wattage units.

45W single-port maximum

The decisive figure is the 45W peak output on a single USB-C port. It enables 30W fast charging for compatible phones and powers a MacBook 14, yet it stops short of the 65W or 90W many 14- to 16-inch laptops require. If your device draws more than 45W, this bank will not charge it at full speed.

Questions about this item

Will the 45W USB-C output charge a MacBook 14 while I still use older USB-A devices?

Yes, the two USB-C ports share 45W PD output and the two USB-A ports add QC support, so a MacBook 14 can draw up to 45W while phones or accessories charge from the USB-A sockets.

How do I confirm the power bank is delivering the advertised 45W rate after I plug it in?

The built-in LED display shows remaining capacity from 0 to 100 percent; pair it with a USB-C power meter on the cable to verify the real-time wattage reaching your device.

Does the box include a 45W wall charger so I can recharge the bank in the claimed 2 hours?

No, the package contains only the 20000mAh power bank and a USB-C cable; a separate PD charger rated at 45W or higher is needed to achieve the 2-hour recharge time.
