Baseus has thrown a very capable brick at the laptop-battery problem. The new Baseus EnerGeek GP12 pairs a 20,800mAh cell with up to 145 watts of total output, enough to keep a laptop, phone, and tablet alive when a wall socket is nowhere in sight.
The power bank can send up to 100 watts to a single USB-C device, while two connected devices share a combined 145 watts automatically. Baseus says that is enough to push a 14-inch MacBook Pro to 55% in 30 minutes, or an iPhone 16 Pro to 57% in the same stretch.
Baseus EnerGeek GP12 charging specs
- Battery capacity: 20,800mAh
- Total output: up to 145W
- Ports: two USB-C and two USB-A
- Single USB-C output: up to 100W
- Input: up to 65W
- Recharge time: around 90 minutes
There’s also a practical side to all this muscle. The unit stores 77Wh, which keeps it within common carry-on airline limits, and Baseus says it is approved for carry-on use on most commercial flights. That matters because the fastest chargers are useless if security turns them into a very expensive paperweight.
Four ports and a screen that tells you the bad news
The GP12 can charge up to four devices at once thanks to its two USB-C and two USB-A ports. A digital display shows battery percentage, charging speed, and estimated time remaining, whether the power bank is feeding your gadgets or refilling itself. Baseus claims the pack can recharge an iPhone 16 Pro about 3.6 times before it needs a wall outlet of its own.
For a crowded market, the formula is familiar: high wattage, airline-friendly capacity, and enough ports to reduce cable arguments on a trip. The difference is that Baseus is pushing laptop-grade output at a price that undercuts many premium competitors, including models from Anker and Ugreen that often ask more for similar power.
Baseus EnerGeek GP12 price and availability
The Baseus EnerGeek GP12 is now available on Amazon for $99.99. Baseus says it has more than 2,100 patents and sells products in more than 180 countries, which is a tidy way of saying this is not a one-off experiment. The real question is whether more brands will start matching this blend of high output and flight-friendly capacity, because that is where the portable charging arms race seems headed.
