This has been on my phone for a DAY, and it charged it once. You truly get what you pay for. This lump of rocks is heavy, and doesn’t even work. Don’t waste you time and money ordering this, and then having to return it. Awful product. The reviews warned me, but I wanted a case quickly. Do NOT buy this worthless product! Now let’s see how long and hard it is to replace it, or get my money back. ### ⭐⭐⭐⭐⭐ Read directions FIRST *by R***. on Reviewed in the United States on January 7, 2020* I love having the extra battery power: the extra weight is well worth it. Just be sure to read the directions first. I almost ruined it by bending the contact when I tried to install it like a regular case. ### ⭐ Owned less than 60 days before it would no longer charge my phone. *by G***D on Reviewed in the United States on February 6, 2020* I tried contacting the seller FNSON by email through Amazon. ZERO response. I expected better. The case would nolonger charge my IPhone 11 Pro Max - I owned it for less than 60 days. --- ## 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/165498944-battery-case-for-iphone-11-pro-max-6500mah-portable-protective](https://www.desertcart.co.uk/products/165498944-battery-case-for-iphone-11-pro-max-6500mah-portable-protective) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-22*
