You might find it slightly heavy for daily pocket carry, but the massive capacity and fast charging make it worth the trade-off.
Should you buy this?
- Buy it if
- You travel frequently and need a reliable, high-capacity power bank to keep your smartphone, tablet, and wireless earbuds charged throughout long journeys without hunting for wall sockets. You own multiple devices and require triple output ports to share power with friends or charge your phone and accessories simultaneously while on the move.
- Skip it if
- You primarily need a lightweight power bank that easily fits into small shirt or trouser pockets without adding noticeable bulk and weight to your daily carry. You expect a power bank to reliably and quickly charge high-power devices like standard office laptops, as the 22.5W output is mostly optimized for mobile phones and smaller gadgets.

How this rating was made
The score comes from one evaluation of the Flipkart specification table against today's cash price, calibrated so most consumer electronics land between 65 and 88. Affiliate partnerships never change a score, and no brand pays for placement. Where the store withholds a specification, the model is told to treat it as unknown rather than assume a good value.
