It also helps that there's a display to show much power you have left before needing to recharge the battery pack. I've been able to charge my TI-Nspire calculator and my iPhone a few times(2-3) before it went down to 60%. In addition, it comes fully pre-charged which is great because it's ready to use.However, the battery itself won't charge properly anymore. After 10 minutes of being plugged in the display goes out and it stops charging altogether. I've tried unplugging and re-plugging everything but it doesn't work. Not sure if mine is defective or not, but I probably won't be able to use it anymore once it completely runs out and I've only had it for about two weeks.Edit: Customer service reached out to me and offered to replace the power bank, they also offered a few suggestions in trying to fix my issue. I changed the cord I was using to charge the device and it worked perfectly. The power bank charges my devices just fine now. ### ⭐⭐⭐⭐ Small, thin, light, inexpensive. Nice battery. *by A***R on April 7, 2017* I bought this as a deal of the day...supposed to be $15.99 but I was charged $18.99. Still a good price though, so I didn't complain. I will soon be using this to see how it works on my phone, but I expect to be able to charge it 4 times. It's light, and thin compared to the RavPower 10000mAh battery I am also happy with. The LED is bright and always on when plugged in. I like that it shows the battery charge as a percentage instead of a 4-LED graph, The case is metal ( aluminum?) and is a gold color. The color doesn't matter to me, as long as it works. So far so good. ### ⭐⭐⭐⭐ Excellent for extending the life of your devices away from ... *by T***D on August 11, 2016* Excellent for extending the life of your devices away from an outlet. Will keep a small tablet going all day long while doing online stuff, 8-12 hours for me at least and will vary via usage and device, was also charging my phone to full once while using it like formerly mentioned. Would be five stars but the USB ports are not very rugged. You drop it while it has a cable attached and you will probably kiss one or both ports goodbye. Happened to me, dropped the power bank/pack and the 2.1 Amp no longer works without some serious physical manipulation and constant pressure holding the USB cable in place just right. Aside from that excellent product. --- ## 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/29222133-polanfo-20000m-power-bank-12000mah-external-battery-for-smartphone-tablets](https://www.desertcart.vn/products/29222133-polanfo-20000m-power-bank-12000mah-external-battery-for-smartphone-tablets) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-22*
