At least one fast-charging port: USB-C Power Delivery ports are starting to replace older USB-C and USB-A ports, in part because they can transmit much more power-up to 100 W with compatible devices, in contrast to just 15 W over standard USB-C and 12 W over USB-A.

At least a one-year warranty and readily available customer support: If you’re spending hundreds of dollars on something and depending on it in tight situations, you want to know that the manufacturer is reachable and reliable in case something goes wrong.

We ended up not testing anything heavier than 2.5 pounds (about the weight of a clothbound copy of War and Peace) or bigger than 60 cubic inches in volume (about the size of a standard brick).

Light and compact enough to fit in a briefcase, backpack, or laptop bag: Although we didn’t set strict size and weight requirements, we did want a charger that was small and lightweight so it would be easy to bring to a coffee shop or on a plane.

On the lower end, we set our minimum at 60 Wh because that’s equivalent to running a 60 W device (such as a 13-inch MacBook Pro) for one hour. Since some people like to work (or watch movies) on their laptop on long flights, we capped our capacity limit at 300 Wh to account for this restriction.

Capacity between 60 and 300 watt-hours: Per TSA regulations, you may transport “spare” or “loose” lithium-ion batteries in a carry-on bag-either one battery up to 300 Wh or two batteries up to 160 Wh each-though for batteries over 100 Wh, like the largest of our picks, you may need to check with your airline first.

An output rating of at least 65 watts: Most MacBooks (except for the 15-inch MacBook Pro) need about 60 W to charge at full speed, so we set our minimum limit at 65 W just to be safe.

Rated capacity: 30,000 mAh (108 Wh) Max output: 149 W Weight: 2.2 pounds Dimensions: 7.0 by 5.4 by 1.8 inches This model is your best bet if you don’t mind some added bulk in exchange for having the most power possible. In addition to the hard-shell case, it comes with a soft mesh pouch and a USB-C charging cable, and its 18-month warranty matches the coverage period on our top pick from Anker. It charged our test laptop 1.2 times (tying with the ChargeTech for the highest capacity), and like our top pick it has a USB-C PD port, two USB-A ports, and an AC outlet.

It’s more powerful than our other picks, capable of pumping out a whopping 149 W to laptops and other power-hungry devices. It’s not our top pick because it doesn’t come with a wall charger, its rubberized finish collects fingerprints, it’s relatively heavy at 2.2 pounds, and it’s bulkier than the rest of our picks (especially in its protective hard-shell case), but it excels in almost every other way. 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.
