ViewSonic J2651 20000mAh Power Bank

The ViewSonic J2651 is a 20000mAh lithium polymer power bank with 35W USB-C Power Delivery and Quick Charge 4.0. It suits travellers and commuters who need to keep smartphones, tablets, laptops and smartwatches powered throughout a full day away from wall sockets.

Easy setup with four ports and a display

Plug a cable into any of the two USB-C or two USB-A ports and charging begins automatically. The digital display shows remaining capacity. Both USB-C ports accept input up to 35W so the bank itself recharges in about two hours. Only the rated 13000mAh at 5V/3A is guaranteed for connected devices; energy conversion rate exceeds 60 percent.

35W bi-directional USB-C decides fit

Each USB-C port handles 5V/9V at 3A, 12V at 2.5A, 15V at 2.3A and 20V at 1.75A for both input and output. If your laptop or tablet requires more than 35W over USB-C, this unit will not deliver full speed. Buyers needing higher wattage or more than four simultaneous connections should look elsewhere.

Should I choose the 20 000 mAh model or a lower capacity version?
