Baseus has added a new power bank to its lineup that is aimed squarely at people who carry too many gadgets and not enough wall sockets. The EnerGeek GP12 packs 20,800 mAh, supports up to 145 W of combined output, and is already on sale for $100.
It also has a 77Wh battery, which keeps it within the usual airline carry-on limits for most carriers. With two USB-C ports and two USB-A ports, the GP12 can push up to 100 W from a single USB-C port, or split power across two USB-C connections for the full 145 W total. In practical terms, Baseus says that is enough to get a 14-inch MacBook Pro to 55% in about 30 minutes, while an iPhone 16 Pro reaches 57% in the same window.
Ports, power and battery size
The battery inside is rated at 77 Wh, which keeps it inside the usual airline carry-on limits for most carriers. That matters more than the marketing copy suggests, because a power bank this ambitious is only useful if you can actually bring it on a trip.
- Capacity: 20,800 mAh
- Battery energy: 77 Wh
- Ports: two USB-C, two USB-A
- Maximum single-port output: 100 W
- Maximum combined output: 145 W
How fast the Baseus EnerGeek GP12 recharges itself
Baseus says the EnerGeek GP12 can accept up to 65 W on input and refill itself in about 90 minutes. That is a sensible pairing for a high-output battery: fast enough to be useful, not so fast that it needs a brick the size of a paperback novel.
The front display is a nice touch, showing remaining charge, current power draw, and an estimate of how long until the pack is empty or full again. It is the kind of detail that should be standard by now, but plenty of rivals still treat battery life like a guessing game.
What 20,800 mAh actually gets you
According to Baseus, a full GP12 charge is good for 3.6 iPhone 16 Pro top-ups. That puts it in the useful-not-absurd category: big enough for a laptop-and-phone day, small enough to stay portable, and priced low enough to undercut some premium high-wattage rivals that lean harder on branding than engineering.
The real question is whether 145 W becomes the new baseline for travel chargers, or whether this remains a niche for people who actually move data and power around all day. Either way, Baseus just made the argument that a compact power bank does not have to be timid.
