The RAVPower 30000mAh AC Power Bank (RP-PB055) may seem expensive for a budget pick, but at this writing we haven’t found anything under $100 that we feel comfortable recommending. Rated capacity: 20,400 mAh (73.4 Wh) Max output: 98 W Weight: 1.4 pounds Dimensions: 5.0 by 4.8 by 1.1 inches Like the ChargeTech, this model is backed by a one-year warranty.

And although it comes with USB-A and USB-C cables, the package has neither a case nor a wall charger. Namely, the Omnicharge has the lowest output (98 W) and capacity (it charged our MacBook Air only to about 80%) of any of our picks, and it’s the most expensive at this writing. If you want those extra features and maximum portability, this is your best option, but there are some notable drawbacks. It’s also one of the few models we’ve seen with dual input options (you can recharge it with DC or USB-C PD), as well as a screen showing you helpful information such as input/output wattage, charge level, and operating temperature.

If you have a phone or other device that can charge wirelessly-such as a newer iPhone, Google Pixel, or Samsung Galaxy-this is the only one of our picks that has wireless charging capabilities.

This easy-to-use charger looks sleeker than most models, seems durable, and has rounded corners that make it comfortable to handle. The Omnicharge Omni 20+ is the most lightweight (1.4 pounds) and compact of our picks.
