Chargeasap asserts that its latest power bank can charge three MacBooks at once thanks to its new max output of 275 watts (W). The 25,000mAh accessory has dual OLED screens to track its remaining battery and status of its individual ports. The Flash Pro Ultra also supports wireless charging for smartphones and smartwatches at the same time.

Chargeasap touts its new Flash Pro Ultra as the ideal power bank for all your ultrabooks, smartphones, accessories (or even your new Nintendo Switch 2 one day), as even its USB-A port has been upgraded to a top rate of 60 watts (W).

The new 25,000mAh portable charger also has 3 USB-C ports: 1 for devices that can charge at up to 60W; one for up to 100W devices and one for those that can use the updated 140W standard. 

Therefore, the power bank could indeed charge 3 of the latest MacBook Airs at once with its "industry-leading" 275W output. The Flash Pro Ultra also integrates up-to-date Qi2 wireless charging, with a new retractable pad for improved compatibility.

The power bank also sports a second, smaller pad specifically for wearables such as the Apple Watch, thereby sustaining up to 6 devices at a time.

It is also rated to re-charge from 0 to 100% in as little as 70 minutes via its fastest 140W port using a compatible power brick (like the Ugreen Nexode 140W listed on Amazon).

Chargeasap has released the Flash Pro Ultra via Kickstarter, amassing over $350,000 in backing already, the first $100,000 of which apparently came in during the campaign's first 3 hours.

The power bank starts at $179, or 46% off its initial retail price, at the time of writing.
