Capacity and use case

The ViewSonic HX200K1 provides 38800mAh of lithium polymer capacity in a black enclosure measuring 5.0 in by 3.5 in by 0.5 in. It targets travellers, campers and anyone needing several days of phone charging away from wall outlets. The pack weighs 432.5g and includes a USB C cable and welcome guide.

Output and input limits

Five USB output ports allow simultaneous charging of multiple smartphones or other USB devices. Two input ports accept 5V/3A recharging through USB Type C. The integrated LED digital display shows remaining charge status. An internal intelligent IC protects against overcharge, over-discharge, overheating and short circuits across 2000+ cycles.

Pre-purchase checks

Verify that your devices charge via USB Type C or standard USB A cables compatible with the five output ports. Confirm your charger can supply 5V/3A for the fastest replenishment of the power bank itself. Note the 38800mAh capacity exceeds typical airline carry-on limits, so this unit cannot be taken on flights.
