16800 mAh portable charger

The Corn Electronics power bank stores 16800 mAh of energy, rated at 84 Wh, and delivers power through two USB ports rated at 5 V / 2.1 A and 5 V / 1 A. An integrated LED display shows the remaining charge, and a built-in LED light provides illumination in dark conditions. The Arctic White finish distinguishes this unit.

Plug-and-play operation

No software or drivers are required; simply connect a device with a standard USB cable to begin charging. The two ports allow simultaneous charging of two devices, though the total output is split between them. The only common issue is attempting to draw more current than the individual port ratings allow, which will cause the bank to limit power or shut down.

Check your devices before ordering

Verify that each device you intend to charge accepts a 5 V input and can operate with either 1 A or 2.1 A supply. Confirm you have suitable USB cables for your connectors, as none are included in the specifications. The bank itself recharges through a micro-USB input, so ensure you have a compatible charger and cable for that purpose. Buyers who need higher voltages, USB-C Power Delivery, or wireless charging should consider a different product.
