ViewSonic P5 Power Bank 50000mAh 22.5W Space Black

Massive 50000mAh capacity

The ViewSonic P5 power bank stores 50000 milliamp-hours of lithium-polymer energy in a Space Black housing. It is built for travellers, campers and hikers who need days of phone and accessory runtime away from wall outlets. The integrated LED digital display shows the exact remaining charge at a glance. Buyers who need an airline-compliant pack cannot use this unit because its capacity exceeds typical carry-on limits.

Four-port USB-C hub

One USB-C port handles 18 W input and 22.5 W output while two USB-A ports each deliver 22.5 W, letting three devices charge simultaneously. A single USB-C cable recharges the bank itself, so no extra proprietary adapter is required. The 5.38 × 2.75 × 1.6 inch footprint and 0.649 kg weight slide into a backpack pocket without crowding other gear. Builders who need wireless charging or a built-in AC plug will not find those features here.

Sustained 22.5 W delivery

Under continuous load the bank maintains 22.5 W across its outputs until the internal cells deplete, avoiding the sharp taper seen on lower-rated packs. The lithium-polymer chemistry supports repeated deep cycles for multi-day excursions. Recharging the bank takes several hours at 18 W input, so overnight top-ups are practical. Users who require pass-through charging while the bank itself recharges should verify that capability separately.
