The Anker Prime bundle covers home and travel with two separate chargers in the same box. When connected to the base, the 100W GaN base plugs into the wall and charges up to three devices through its own USB-C and USB-A ports. Away from the base, the battery outputs up to 250W via two USB-C ports and a USB-A port on the top edge, enough to charge a MacBook Pro at wall speed. Recharging the battery itself takes no more effort than setting it back on the base. Magnetic pins on the bottom line up with matching pins on the base, and the recharge starts automatically.

An easy way to ensure all your devices are charged at your home base

Anker rated the Prime at 27,650 mAh, which comes to 99.54 watt-hours. Airlines cap lithium-ion batteries in carry-on bags at 100 watt-hours, so the Prime slides in just under that ceiling with no paperwork required. On a long-haul flight, that battery refills a MacBook Air about 1.28 times, an iPhone almost five times, or keeps a mix of phones, tablets, and earbuds topped up for an entire travel day away from a wall outlet. The included magnetic base holds the bank upright on a desk, with the LCD panel facing forward for quick glances at charging status.
