The Omnicharge is the lightest (1.4 pounds) and most compact of our picks, and it looks sleeker than most models, with rounded corners that make it comfortable to handle. It’s also one of the few models we’ve seen with dual input options (you can recharge it over DC or USB-C), as well as a screen showing input/output wattage, charge level, and operating temperature. If you have a phone or other device that can charge wirelessly, the Omnicharge Omni 20+ is the only one of our picks with wireless charging capabilities.
