When traveling across continents, embarking on multi-day camping treks, or commuting long hours away from wall outlets, the INIU 20,000mAh 22.5W Portable Charger (Model BI-B5) provides the massive energy reserves you need. Engineered with a true 20,000mAh (74Wh) internal battery array, this workhorse delivers up to 4.5 full charges for an iPhone 16, nearly 4 charges for a Samsung Galaxy S25, or two complete charges for an iPad Pro, eliminating low-battery anxiety entirely.
🛠️Craftsmanship & Ergonomics

Housed in a shock-absorbing, rubberized anti-slip enclosure with an ergonomic curved profile, the BI-B5 withstands the bumps and scrapes of airport terminals and travel backpacks. The front panel features INIU's signature numeric LED paw battery indicator, which clearly displays remaining power down to the exact single digit percentage. An integrated high-lumen emergency LED flashlight adds valuable practicality during power cuts, roadside emergencies, or searching inside unlit tent compartments.

Equipped with 22.5W high-speed USB-C Power Delivery and Quick Charge 4.0+ outputs, the power bank rapidly fuels devices without sluggish charging lags. It supports tri-device simultaneous charging via its dual USB-A ports and USB-C port, while INIU's 15-layer SmartProtect thermal management ensures safe, reliable operation. Operating at 74Wh, it remains comfortably within the FAA and TSA 100Wh airline carry-on limit, making it the supreme choice for long flights and road trips.
