The case isn’t as heavy as most charging cases. The charge you get is awesome. Went from 18% to 90% the case still had some juice too but I just turned it off. The grip feels good in my hands. The case also has a button to turn off/on the charger feature which is great. I had other cases that didn’t have that. Just overall the case is great and works great. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Good quality and sufficient battery life. *by A***N on Reviewed in the United States on December 22, 2023* The battery phone case is pretty good quality and has enough battery in it. I got my entire day without having to charge my phone separately because I’m always working. Big plus is a little stand on the backside because I can watch videos putting it on my desk, not having it to lean it against something. Like other phone cases it’s not very heavy either, happy with a purchase ### ⭐⭐ 2.0 out of 5 stars Bad Charging Method *by J***D on Reviewed in the United States on April 16, 2024* Wish i looked a little more into it before buying. But despite the great look and feel of the case and the battery life, trying to charge it and your phone is a nightmare. To charge your phone with the case plugged in you have to activate the button to charge, but majority of the time it just doesnt work, or gives an odd warning on the iphone. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/96005001-runsy-iphone-xs-max-battery-case](https://www.desertcart.co.uk/products/96005001-runsy-iphone-xs-max-battery-case) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
