Highly recommend this!! ### ⭐⭐⭐⭐⭐ Reliable Power Bank With Built In Cables *by J***O on January 3, 2026* We grabbed this Charmast portable charger because someone in our family always seems to hit 5 percent battery at the worst possible time. This thing has already earned its place in the backpack. The built in cables are super handy. I don’t have to hunt around for a charging cord or worry about forgetting one at home. You just plug in and go. It holds a ton of power. We’ve gotten multiple (2-3) full charges out of it before needing to plug the charger back in, which has been great for travel days and long outings. It is a little heavier than the tiny pocket sized chargers, but that makes sense with how much capacity it has. I’d rather carry a little extra weight and know I am not scrambling for an outlet. It charges phones and tablets at a good speed, not instant, but definitely faster than those older cheap battery packs. The built quality feels solid too. Nothing flimsy or rattly. Overall, this has become our go to backup battery for trips, kids’ activities, and just everyday life when batteries run low at the wrong time. We bought 4 of them one for each person in our family and it they have all been working great for the past few weeks. ## Frequently Bought Together - Charmast 20000mAh Portable Charger with 4 Built-in Cables & 6 Outputs, 20W Power Bank Fast Charging - USB C External Battery Pack for iPhone 16 15 14, Android, iPad, Tablet & More (Travel Essential) - Topicals Faded Brightening Under Eye Masks | Revitalizing Patches to Depuff, Hydrate, and Illuminate | Diminishes Dark Circles and Fine Lines | Made with Kojic Acid, Caffeine & Niacinamide - BIODANCE Bio-Collagen Real Deep Mask, Hydrating Overnight Hydrogel Mask, Pore Minimizing, Elasticity Improvement, 34g x4ea --- ## 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/595294118-charmast-portable-charger-built-in-cables-20000mah-power-bank-6](https://www.desertcart.us/products/595294118-charmast-portable-charger-built-in-cables-20000mah-power-bank-6) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-22*
