Review: Extra Large Portable Power Bank from AdventureUltra

With all of the disaster news, and the upcoming snowy weather, I'm tempted to buy a generator. Instead, I have the AdventureUltra ($129.99) from myCharge. This compact device can simultaneously power multiple devices from an iPhone to a 42-inch TV, thanks to two USB-A ports, one USB-C port, and an A/C power port, making it ideal for tailgating, camping, or emergencies.

The built-in battery offers 13,400 mAh of power and recharges using the included external "wall wart" charging brick. The built-in display indicates how much power you have left, with eight distinct levels, and which ports are in use. The device supports up to 45 watts total, and should you try to plug in a device that consumes too much power, you will see a "Max Power Exceeded" message.

The AdventureUltra from myCharge may not power your whole house, but it should be able to power a computer and several iPhones or other USB devices for a few hours.
