Power banks lose energy during charging due to heat and voltage conversion, typically supplying 60%-70% of their power to other devices. Therefore, a fully charged Charmast 20,000mAh power bank can deliver about 12,000-14,000mAh to your devices. Can this power bank be taken on airplanes? Carry-on allowed. Do not pack in checked baggage. Does it work with small devices? Yes. Enable low-current mode for headphones, watches, etc. Is it normal for the portable charger and phone to get warm while charging? Yes. Some warmth is normal during charging and use due to energy conversion. If temperatures exceed 45°C (113°F), stop use immediately. Is it compatible with laptops? No. Use a 30W+ laptop charger instead. 22.5W with 6 Out & 4 In 22.5W with 6 Out & 4 In 22.5W with 6 Out & 4 In 22.5W with 6 Out & 4 In 22.5W with 6 Out & 4 In 22.5W with 6 Out & 4 In 22.5W with 6 Out & 4 In Founded in 2017, Charmast blends reliability with refined design, trusted by 38M+ users worldwide.

It takes awhile to charge the actual bank so I leave it on over night and its full by morning. But it charges your phone do quick! Faster than the mains. It kept me and my sister going all holiday. Say it was on 80 % it recharged mine and my sister from 20% to 100% and probably still had another 30-40% left. Highly recommend. It’s a little bulky and heavier then say an apple one but less then half the price of an apple one and if you need for holidays and not every day it’s brilliant but I only say that because I have a small bag but if you take a normal size bag it won’t be a problem. ### ⭐⭐⭐⭐⭐ Quality charger you won’t be disappointed *by on Reviewed in the United Kingdom 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 on Reviewed in the United Kingdom 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. ## 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. - Charmast Power Bank with Built in Cables X 4, 10000mAh USB C Battery pack 6 Outputs 3 Inputs with LED Display Type C Powerbank Portable Charger Compatible with Smartphones Tablets and More --- ## 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.co.za/products/611808606-charmast-22-5w-fast-charging-power-bank-4-cables-portable](https://www.desertcart.co.za/products/611808606-charmast-22-5w-fast-charging-power-bank-4-cables-portable) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-19*
