Flash Pro Ultra

Carrying a phone, a laptop, earbuds and a watch means carrying a lot of chargers. The Flash Pro Ultra, developed by ASAP Technologies, is pitched as a way to consolidate them. The maker describes it as the world's first power bank with 275W output, built around a 25,000mAh battery intended to handle tablets and laptops as well as phones.

Power and capacity

According to the maker, the unit supports 140W fast charging, aimed at power-hungry devices such as laptops, with USB Power Delivery (PD) laptops singled out as a key use case. The company also says the power bank itself can be fully recharged in 70 minutes, which addresses a familiar weakness of high-capacity batteries.

Wireless and multi-device charging

The Flash Pro Ultra includes Qi2 wireless charging compatible with Apple's MagSafe, so iPhones and other MagSafe devices can charge without a cable. The maker also lists support for Apple Watch and Samsung Watch. A mix of USB-C and USB-A ports allows up to six devices to charge simultaneously, according to the campaign.

• 25,000mAh battery
• 275W output (maker's claim: world's first)
• 140W fast charging
• Full recharge in 70 minutes, per the maker
• MagSafe-compatible Qi2 wireless charging
• Apple Watch and Samsung Watch support
• Up to six devices at once via USB-C and USB-A ports
• OLED screen showing battery level, charging status and per-port activity

An OLED screen instead of LED dots

Rather than a row of indicator LEDs, the Flash Pro Ultra uses an OLED display that the maker says shows remaining charge, charging status and the usage of each port in real time. ASAP Technologies, which has previously made charging products, presents the device as a compact portable power source for remote workers and creators running laptops and camera gear away from an outlet.
