I have tested hundreds of portable chargers over the years, but the Anker Laptop Power Bank ($94, down from $135) is my current upgrade pick of the best power banks. It’s 30 percent off for Prime Day, and that’s the cheapest price I’ve seen for this charger. Remember, Prime Day ends tonight, so this deal won’t last long.
If you want something that can fast-charge your phone, juice up your tablet, and even refill your laptop, look no further. This chunky power bank is packing serious heat, with a smart and practical design, plenty of speedy charging ports, and a handy display.

The Anker Laptop Power Bank is a versatile beast. The generous 25,000-mAh capacity is enough to charge most phones more than four times over, but it stops shy of the limit for carry-on air travel. The maximum output is 165 watts to charge two devices at once; the limit is 100 watts for a single device connected via USB-C. That makes it perfect for recharging a MacBook Pro, even under load.
The lovely rounded edges make it comfortable to handle, and there’s a retractable, flat, 2.3-foot USB-C cable on the top. You also get a snazzy and durable braided 1-foot USB-C cable that doubles as a carry loop. No need to worry about forgetting your cords.
The LED display provides a wealth of information, including the remaining battery level, charging rate in and out, battery temperature, and health. Plug into an outlet and you can fill the Anker Laptop Power Bank from empty in just two hours. It also supports pass-through charging, so you can plug devices in to charge while it recharges (though it’s probably best not to).
This power bank fast-charged everything I tested it with, including a range of smartphones, a couple of tablets, and a MacBook. Alongside the two built-in USB-C cables, you’ll find a USB-A port and a USB-C port. You can charge four devices at once without a worry, though this does drop the maximum overall output to 130 watts.
