Fast, Durable, and helpful! Reliable too! - Short: Had mine for 3-4 years and it still work like the first day I got it, it charges my phone half full in about 20 minutes, I really like it's easy to carry and fast to charge, helps give your battery a boost if needed. I use everyday and would buy another! Rant: Had mine since 2021/2022 so about 3-4 years and it's still working well! I got a pink one as it was on sale and have used it ever since, charges my S25 Ultra from about 4% to 60 in about 20 minutes or so, handy as my phone battery dies a lot. This bank also charges very fast so by the time your phone runs out of juice you're either getting in bed with about 10-20 percent and basically have a charger next to you. And even it died again and let's say you had a long day, by the time you need to charge again you could've charged about 30 of these haha. Also I've had times of being super low in power and even one bar or battery on this beast gets you a good 12 percent or so, enough for an hour or two! When this breaks I'm definitely getting another one, or I might get another colour as a backup even though 1 does just fine! Review: Nifty little portable charger - This has been invaluable!

It charges up quickly and charges up devices (normally my phone) swiftly too, whilst being small and portable. ## Features - ⚡🔋【Specially Designed for USB C Output phones】Widely compatible with most of USB C connection phones like Samsung,Huawei,LG,HTC,Moto,OnePlus,Google Pixel,Xiaomi,OPPO,VIVO,TCL and other Type C phones.

Nifty little purchase that has already been worth the money. It charges up quickly and charges up devices (normally my phone) swiftly too, whilst being small and portable. ### ⭐⭐⭐⭐ Really good if you're out all day and need a bit of juice *by L***N on 25 July 2025* Really good power bank and charges really quickly. Very handy if you're out and about all day and are using your phone a lot, like when youre on holiday. It's also small enough to fit into a small bag. I gave four stars because it only charged one phone from dead, to about 64% then died. It also got quite hot. Would have liked the battery life to last a bit longer. Would definitely recommend and was good value for money. ## Frequently Bought Together - Charmast Mini Power Bank USB C 5000mAh,20W PD 18W QC USB C Battery Pack Quick Charge Portable Charger Compatible with USB C Phones Samsung Huawei,Pixel,LG,HTC,Moto,OnePlus,Xiaomi and More - Charmast 5000mAh Mini Power Bank,20W PD Quick Charge Battery Pack Portable Charger Pack Compatible with iPhone 14/13 Pro,Pro Max,12,12 Pro,12 Pro Max,11 Pro,XR,X,8,7,6 Plus,Airpods Pro etc. --- ## 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.jp/products/450965996-charmast-mini-power-bank-usb-c-5000mah-20w-pd-18w](https://www.desertcart.jp/products/450965996-charmast-mini-power-bank-usb-c-5000mah-20w-pd-18w) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-01*
