The 3 Best Portable Laptop Chargers of 2025
Top pick
This portable charger has an AC outlet, two USB-C ports, and a USB-A port, and it can charge even the most power-hungry laptops. But you need to provide your own wall charger.
The Mophie Powerstation Pro AC is the best portable charger with an AC outlet for people who want to charge a laptop (or other devices drawing up to 100 W) while on the go. It’s supremely powerful, has great battery life, and it’s the only model we’ve tested with multiple fast-charging USB-C PD ports as well as a standard USB-A port.
It supplies a lot of power. This Mophie model has the best AC output of the models we’ve tested, cranking out 174 W to our array of halogen bulbs. This is more than enough power to charge most laptops while they’re in use, even heavy-duty business or gaming laptops.
It has great battery life. With a rated capacity of 27,000 mAh (or about 97.2 Wh), the Mophie comes very close to the TSA’s maximum capacity limit for spare batteries without exceeding it. So, if you like using your laptop on long flights, rest assured that you can bring it on a plane in your carry-on luggage. (Many airlines now require you to keep spare batteries within arm’s reach, rather than in an overhead bin, so you should plan to pack it in your under-seat luggage.)
In our testing, this model was able to charge our test laptop 1.9 times. In other words, it fully charged our MacBook Air once, and then (after fully depleting the laptop’s battery) brought it from 0% to about a 90% charge.
It charges and recharges fast. To recharge itself, the Mophie has a USB-C PD port rated for 60 W input and output. We confirmed these optimal charging speeds in our testing, measuring up to 63 W in and 62 W out.
The unit also has a second, slightly less-powerful USB-C PD port, which is handy for charging a phone or other small device. We measured a maximum output of 24 W from this port in our testing, which is more than enough power to charge the latest iPhones at top speed.
It’s about the size of a paperback. Measuring 7.5 inches tall, 4.5 inches wide, and 1 inch thick, the Mophie has a compact size and shape that’s easy to slip into a backpack or nestle inside a suitcase.
It has a sleek, upscale look. Batteries are rarely beautiful, but this one has a streamlined, professional look. It’ll blend into its surroundings, whether you’re working out of a high-rise building or an RV.
It has helpful battery-status lights. Four small lights next to the power button indicate roughly how much battery life remains.
It has excellent build quality. Unlike our other picks, it has a rubber cover over the AC outlet, which is useful for keeping out moisture and dust that could damage the internal components. Helpfully, the cover is attached by a small tether so you won’t lose it.
Also, one of the corners has an attached nylon strap that’s useful to loop around a few fingers while you’re carrying it to prevent drops.
The entire unit is encased in a matte-black metal shell that seems relatively resistant to scratches and scuffs, and it feels solidly built overall.
It’s a great value. As of this writing, it costs $150, which is less than many contenders with the same (or less) rated capacity.
It has a longer warranty than other options. Made by a company we trust, this charger is backed by a two-year warranty, which is longer than the coverage on any of our other picks.
Flaws but not dealbreakers
It’s on the heavier side. This is one of the heaviest models we’ve tested, at 2.2 pounds. But it’s still quite portable, weighing about as much as a 1-liter bottle of water.
It doesn’t come with a wall charger. This model comes with a USB-C charging cable but no charging brick, so you’ll have to supply your own USB wall charger. But that’s true of most available models.
It has only one USB-A port. This model has a single USB-A port, whereas most we tested have two. But since it has two USB-C ports, both of which charge phones and other handheld devices faster than any USB-A port, this is a tiny quibble.
