Functional & Utilitarian

I have used it for 2 charge - recharge-discharge cycles. Performed what was claimed - I was able to charge a laptop from 30% - 100% in about 45 minutes of time & still had about 38-40% of charge left (mostly linear).. So does its job. I would want to monitor its performance over the next few months.

The build quality could have been better... gives the feel of some low grade plastic material. The LED indicators are clear and crisp. While charging, ocassionally it displays 0W but charging will be in progress. Need to fix this part by way of a firmware update ?

Perfect for Flights Traveler

ought this for international work trips, and it’s a game-changer. The 100W output charges my MacBook Air just like the wall adapter. It’s compact, lightweight, and flight-allowed, which is essential. The digital readout of voltage and wattage helps track usage precisely. Definitely a professional-grade power bank.

Truly Fast Charging

Unlike some other brands that advertise fast charging but don’t deliver, this one actually lives up to the promise. It charged my Samsung S23 Ultra from 20% to 90% in under 40 minutes.

Great powerful powerbank

It’s a great power bank that can charge most of your devices efficiently. When using a single USB-C port, it delivers a maximum output of 100W. However, when multiple ports are used simultaneously, the total output is shared between them, with the power being divided across all active ports. The built-in display shows real-time charging wattage for each connected device, and the power bank itself can be recharged at up to 60W. Overall, it's a very useful product with excellent capacity for its compact size.

Quick Charge

Tested on my Galaxy S23 Ultra and it gave full Quick Charge 3.0 speed. Battery holds well. Digital readout is excellent. I like being able to see real-time amp and watt usage.
