Pocket-Size 20000mAh Capacity
The ViewSonic P512 delivers a true 20000mAh lithium-polymer cell in a compact 4.1 in x 2.8 in x 1.2 in black chassis. It targets travellers and daily commuters who need roughly four full phone charges without carrying a bulky brick. The integrated digital display shows remaining capacity at a glance.
Detachable Nylon Lanyard Cable
A built-in USB-C cable doubles as a woven nylon lanyard, removing the need to pack a separate cord. Two additional USB-C ports sit alongside it, so three devices can charge simultaneously from the single 12 V source. The 5.4-hour recharge time refills the bank overnight.
Sustained 22.5W Output With Thermal Sensors
Under continuous load the bank maintains 22.5W fast charging, taking a compatible handset to 70% or 60% in 25 minutes while active thermal sensors dissipate heat. Over-charging protection stops current flow once a device reaches full capacity. A built-in flashlight adds utility during power cuts or low-light travel. TSA-approved 20000mAh rating clears airport security.
