Ready for travel and long days

This 20000mAh power bank targets users who need several full phone charges away from a wall outlet. The lithium polymer cell stores enough energy for roughly four iPhone 15 cycles or 3.79 Samsung S24 cycles. It suits commuters, frequent flyers and anyone carrying a single cable-free charger for a full day.

Built-in cable rated for 10000 bends

A 5.98-inch USB-C tether folds into the 4.72 x 2.89 x 1.24 inch black chassis weighing 365 grams. The integrated cord removes the need to pack a separate cable and survives repeated flexing in a bag. USB-C serves as both the 30W output and the 20W input port, while ActiveShield 2.0 monitors temperature continuously for safe operation.

30W two-way fast charging decides fit

Maximum output reaches 30W, pushing an iPhone 15 from 0 to 57 percent in 30 minutes, and the bank itself recharges in about 5.1 hours with a 20W charger. Pass-through works at 5V/3A but not for laptops. Buyers whose laptop demands more than 30W or who need wireless charging should look elsewhere.
