When I tried charging it, the whole inside fell out! I wasn't too upset though since it gave me an opportunity to properly set the battery pack and put it back inside. But unfortunately, a month later I started hearing it rattle inside again and it fell out again... this makes me want to give a rating of a minimum of 3 stars but it charges so fabulously and so quickly that I am in a dilemma about the score....so I'll give it a 4 since it does its job well and I probably just have a defective casing. ### ⭐⭐⭐ Just ok. *by K***M on Reviewed in the United States on November 15, 2016* Very sleek and pretty design. Hard to determine if it is charging though. Additionally, I have been unable to charge two devices at once, even though there are two ports. It seemed to confuse the device as it kept switching back and forth between the two. ### ⭐ Fancy battery, doesn't work though. *by M***. on Reviewed in the United States on October 27, 2016* First battery that came in was broken, it could not charge itself. Not only that the amount of energy it held was definitely not 20,000 mah. I wrote to customer service stating my problem and they sent me a replacement. The replacement could charge, but it was definitely not 20,000 mah. I tested this out by charging one of my devices that has a battery of 3400 mah. The battery pack went from 100 to 50 after only charging the device 60 percent of the way. I retested it by charging the battery pack overnight and then used it to charge my 10,000 mah external battery. My external battery isn't even charged 25% before the smart modern battery dropped 75%. Not only that but when I remove the USB, the casing slightly comes off. The quality of the battery is pretty bad and I very much doubt that with the size and weight, it could hold 20,000mah worth of charge.Customer service was quick and responsive, but overall did not solve the problem. I'm not sure why it has such high reviews, two orders of batteries and they both don't work. Good thing for refund though. --- ## 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.vn/products/29938199-smart-moderns-new-ultra-slim-20000mah-aluminum-external-battery-pack](https://www.desertcart.vn/products/29938199-smart-moderns-new-ultra-slim-20000mah-aluminum-external-battery-pack) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
