Tech Test: Cuktech 15 Air Tops Charging Speed
17 Jun
Summary
- Cuktech 15 Air charges fully in 54 minutes.
- Anker Prime boasts higher capacity, charges in 100 minutes.
- Testing measured energy input for accurate charge times.

A rigorous comparison of 10 popular power banks has identified the Cuktech 15 Air as the fastest charging device. This model achieved a full charge in a remarkable 54 minutes. Testing focused on measuring energy input from the wall using a HOBOware plug load logger to ensure accurate charge-completion milestones.
The Cuktech 15 Air also reached a 50% charge in approximately 26 minutes, offering a quick power boost. Notably, it supports pass-through charging, allowing it to power other devices while being recharged itself.
In comparison, the Anker Prime power bank, with a significantly higher 250Wh capacity, took 100.2 minutes to fully charge. The Baseus EnerGeek GX11 MiFi was the quickest to reach 50% charge (just over 13 minutes) but required over three hours for a full charge, likely due to its multi-device hotspot functionality.
