Omars Backup Battery 20000mAh

Our testers were able to run extensive tests on two of these external batteries, in fairly extreme conditions (particularly regarding humidity), and were rather impressed by their performance and ruggedness. Neither unit ever failed, even under difficult conditions.

With 45W of max power, this power bank is a beast capable of powering particularly demanding devices, such as certain handheld consoles (we were able to test it on a Nintendo Switch) or laptops like the 13'' MacBook — which it can fully recharge once — thanks to its impressive 20Ah (72Wh) capacity.

Quite heavy (over 500 grams), largely due to its aluminum chassis, and fairly large, it isn't meant for ultra-nomadic use. That downside aside (the weight being the trade-off for the ruggedness of the aluminum), this power bank from Omars will prove indispensable to anyone who needs power. With the right wall charger (PD 45W), this battery charges fully in about 2 hours, 4 times faster than a standard power bank — you can watch the battery percentage climb on the blue digital display.

Supplied with a very handy 2-in-1 cable, this power bank has 2 USB-A ports (a standard DC 5V⎓2.4A port and a fast DC 5V⎓3A/9V⎓2A/12V⎓1.5A/QC 18W port) and 1 USB-C In/Out port (5V⎓3A/9V⎓3A/12V⎓3A/15V⎓3A/20V⎓2.25A/PD 45W). In summary, an excellent high-power, high-capacity external battery at a very reasonable price.
