Anker · Reviewed by Aman Dhingra · Published 2026-02-08
Based on a review by Aman Dhingra (accessed 2026-02-08).
Based on this review alone: buy it if you care about extremely compact and lightweight — just accept only 5000mah capacity.
The reviewer highlights the Callmate Shotgun as his personal favorite due to its unique, reloadable design and compact form factor. He concludes that while all listed power banks are unique, the Callmate Shotgun stands out for its distinctiveness.
This review tests and compares five portable power banks, including models from Ambrane, Xiaomi, Stuffcool, Anker, and Callmate. The reviewer evaluates each power bank based on its size, portability, build quality, charging capabilities, and unique features, aiming to identify the best option for various user needs.
The Anker Nano power bank is a highly useful and compact option, particularly when purchased during a sale, offering more practical utility than its Xiaomi counterpart. Its standout feature is the integrated flip-out USB-C connector, allowing direct attachment to a phone for charging while in use. It also supports IQ 3.0 fast charging, but its regular price point of ₹2500 makes it less appealing compared to its utility. If you prioritize an ultra-compact, directly attachable power bank for on-the-go charging during phone use, this is worth considering during sales. For those needing higher capacity or a standard power bank without a premium price, other options might be better.
