Therefore, a fully charged Charmast 20,000mAh power bank can deliver about 12,000-14,000mAh to your devices. **Q: Can this power bank be taken on airplanes?** A: Carry-on allowed. Do not pack in checked baggage. **Q: Does it work with small devices?** A: Yes. Enable low-current mode for headphones, watches, etc. **Q: Is it normal for the portable charger and phone to get warm while charging?** A: Yes. Some warmth is normal during charging and use due to energy conversion. If temperatures exceed 45°C (113°F), stop use immediately. **Q: Is it compatible with laptops?** A: No. Use a 30W+ laptop charger instead. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality charger you won’t be disappointed *by B***Y on 27 July 2026* This solved my charging issues .was initially surprised it didn’t come with a charger but the wires are attached and the usb wire is for input .I have only had it a few days but it charges my phone quickly and uses a small percentage of the power displayed .I just love how the different wires are integrated so can’t get lost and are always to hand .seems good quality recharges quickly and has a little bag so easy to carry around ### ⭐⭐⭐⭐⭐ 20 w fast charge powerbank *by L***Y on 3 August 2026* A great power bank with 20000Mah comes with 4 different size cables attached to the back so no messing around looking for a cable to plug into it. A decent price, so far I have charged my phone up 3 times from a full charge. It's about the size of a smartphone, fast charging, I recommend this power bank it certainly works for me. ### ⭐⭐⭐⭐⭐ Amazing, but be cautious of overheating *by J***H on 11 April 2026* This is one of the best charging blocks that we’ve come across. It’s pretty hefty and is heavier and thicker than our phones but it’s sturdy as hell! It looks sleek and smart and being able to see the charge remaining on the back in big OLED numbers is great! No more more carrying around 3 separate wires for my phone, partners phone and our son’s tablet, this has all three chargers that we need! It will charge my just my partners iPhone 11 or just my son’s kindle fire hd10 about 2-3 times before it needs charging again. Unfortunately it will only charge my power hungry iPhone 17 pro max 1-2 times before needing charging again. It charges relatively quick and if we but it on charge before we go to bed, it is done by morning. Honestly it’s so great that since getting my power hungry phone we’ve bought a second of these so that my phone can have one and my partner and son can use the other. It charges stuff much faster than regularly. The ONLY small downside of this power bank is that we’ve found that because it charges stuff so quick both the bank and whatever we are charging get very hot and before we knew how hot it was, it actually burned my skin. So we have to be careful about what surfaces we charge on and we make sure that the power bank and device aren’t stacked to try cool them down a bit ## Frequently Bought Together - Charmast Power Bank with built-in Cables,20000mAh 20W PD QC Quick Charge Portable Charger USB C Power Bank Fast Charging compatiable with iPhone iPad Samsung Galaxy etc. - Worldwide Travel Plug Adapter, FSTravelP Universal with 2 USB International AC Socket Dual 10A Fuses, All In One Adapter for USA UK EU AU CN 150+ Countries --- ## 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.us/products/611808603-charmast-22-5w-fast-charging-power-bank-4-cables-portable](https://www.desertcart.us/products/611808603-charmast-22-5w-fast-charging-power-bank-4-cables-portable) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-16*
