Aohi launches 310W Starship Pro powerbank with 20000mAh battery for just $70
Aohi has introduced a new high-capacity power bank for people who carry more than just a phone. The Future Starship Pro 310W packs a 20,000mAh battery and, at least on paper, enough power to replace multiple chargers in your bag. It’s priced at 499 yuan and comes in a silver-gray and black finish with a small display on the front.

The device measures 45.6 x 57.6 x 158mm and weighs around 630g, so it’s not exactly pocket-sized. But considering what it promises, the size feels expected. On the front, there’s a 1.14-inch TFT color screen that shows battery level and real-time output information. So instead of guessing how fast your laptop is charging, you can see the numbers directly.
Aohi 310W Starship Pro Specifications
The headline feature here is power output. The Starship Pro uses a 2C + 1A port configuration: two USB-C ports and one USB-A port. Both USB-C1 and USB-C2 support up to 140W input and output individually. The USB-A port tops out at 30W. When all three ports are used at once, the combined maximum output reaches 310W (140W + 140W + 30W), with what Aohi calls “smart power distribution” to manage charging across devices.
That means it’s technically capable of charging two high-power laptops at the same time, while still topping up a phone or accessory. It supports common fast-charging protocols including PD, QC, PPS (up to 100W), and UFCS (63W), which should make it compatible with a wide range of devices.

Aohi claims the 20,000mAh capacity can charge an iPhone 16 up to 4.1 times and a 12.9-inch iPad Pro about 1.4 times. The rated energy is 72Wh, using eight 2,500mAh lithium-ion cells from DMC.
What may matter even more for frequent travelers is recharge speed. The Starship Pro supports up to 180W self-charging input. In theory, that allows the power bank to go from 0 to 100 percent in around 60 minutes.
It’s still a relatively heavy device at 630g, but for users who carry power-hungry laptops, tablets, and phones, the trade-off might make sense.
