There was so many power banks to choose from but this ticked all the boxes of what we needed. 20,000 mah lasts him 2 days if not longer and there is a screen on it which lets him no how much percent is left before it will need charging ( so no excuses). The power bank comes in a lovely stylish blue colour and is lightweight so can be carried in his coat pocket without weighing him down and is cool enough that he can pull it out.No problems with any over heating or burning up like an old one i had. For a 12 year old always on the go boy its lasted with knocks and bangs and still is going great . Overall fantastic buy for the price... i may even need to return and buy myself one. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great power bank *by G***A on Reviewed in the United Kingdom on 8 February 2019* Well, I am a maniac of power banks, I have more than 5 in my house, but can't stop getting more as it is very universal present and saves us from hassle looking for charger living in high tech world. This power bank does have digital display to tell you how many percents left, have a light on (honestly in the last 5 years I've not used it even a single time), two usb slots and one micro usb slot to charge power bank itself. It does have a good reviews and it does work good, I used it on out travel to London and back to charge up both kids tablets and it's deffo holds the charge. It lasted me a full 3 tablets charge, so pretty good capacity and price. It is not really lightweight, but I wouldn't expect it bearing in mind it's capacity. I do like unusual coloir of the power bank, digital screen and efficiency ### ⭐ 1.0 out of 5 stars NOT 20,000mah & NOT FAST CHARGE *by N***L on Reviewed in the United Kingdom on 14 February 2019* I had a 10,000mah power bank before (which I lost) with fast charge & same percentage display (which I love) & was tiny bit smaller. I thought I'll get this one as it similar size & states 20,000mah capacity, fast charge with display. I can truly say, this did not last longer than the 10,000mah one & it definitely does not charge fast, just normal speed. You get what you pay for. I paid the same amount for a 10,000mah one. And I thought this one is 20,000mah and would last longer, but it did not, & it doesn't charge as fast too. No wonder its light. The heavier a battery is, the more mah its got!The quality is not good either. Its rigid & made from poor plastic. It just looks good in the picture. I'm sending this back & getting the same one I had before. --- ## 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/89904455-power-banks-20000-mah-portable-phone-charger-with-2-usb](https://www.desertcart.vn/products/89904455-power-banks-20000-mah-portable-phone-charger-with-2-usb) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
