20 000 mAh 45 W Portable Charger

The JUOVI J2621 is a 20 000 milliamp hour lithium polymer power bank that delivers up to 45 W through two USB-C and two USB-A ports. A digital LED display shows the remaining charge from 0 to 100 percent. The 74 Wh capacity complies with airline carry-on limits.

Travellers and multi-device users

Four simultaneous outputs suit people who carry a laptop, phone, tablet and accessories on long trips or commutes. Buyers who want wireless charging or a magnetic attachment should look at a different design because this model uses only wired ports.

Check your charger and cables

Full recharge in two hours requires a separate 45 W or higher PD wall charger, which is not included. Verify that your devices accept USB-C PD or USB-A 5 V 3 A input so they can draw the rated speeds.

Questions about this item

What type of wall charger do I need to recharge the JUOVI J2621 at its fastest rate?

A USB-C PD charger rated at 45 W or higher is required to refill the power bank in about 2 hours; lower-wattage chargers will take longer.

Can I keep using my older USB-A cables with this power bank?

Yes, the unit provides two USB-A ports alongside two USB-C ports, so legacy cables work for up to four devices at once.

How do I confirm the power bank is delivering the expected charge level after I plug in a device?

The built-in digital LED display shows remaining capacity from 0 to 100 %, letting you verify output in real time.
