I like the fact you can disable the auto-shutoff feature. The over all size is about two cell phones placed on top of each other. It has four cables on the underside. The USB C port is bi-directional so you can charge the unit and then later charge your device. In addition to the USB C, it has two USB ports as well. It also has a three digit LED light which tells you what percentage of power is left in the bank. Review: Lots of power with lots of options! - This power bank is incredible! I love that it has the 4 most common plugs already attached. This feature has enabled me to use it at work for the iPad that is always dying before I am able to finish my task. It's great in the car on long journeys because I can charge both my phone and my tablet and still use them regardless of where I am sitting in the car. It charges both my android phone and my android tablet quickly. It's been an all around great power bank and I highly recommend it. ## Features - Stay Powered Anywhere: This 20K portable charger delivers 3-4 full phone charges - ideal for camping, flights, or emergencies.

It's been an all around great power bank and I highly recommend it. ### ⭐⭐⭐⭐⭐ Great purchase- works so well *by N***G on July 15, 2026* I love this charger. I have used it everywhere -traveling, for my phone, computer, various accessories (kids iPad, portable fan, bottle warmer, anything and everything). The different plugs make it compatible with basically any charging port. The battery life lasts a very long time. I’m able to fully charge my iPhone multiple times before having to charge it. Size is similar to an iPhone, however it is a bit heavier. Charging it doesn’t take too long considering how much power it provides once fully charged. Very happy with this purchase. ## Frequently Bought Together - Charmast Power Bank 20000mAh, 20W Fast Charging Portable Charger with Built-in Cables, USB C Battery Pack, Slim Portable Phone Charger Backup Battery for iPhone, Samsung, iPad, More Phones, Tablets - Portable Charger with Built in Cables, Portable Charger with Cords Wires Slim 10000mAh Travel Battery Pack 6 Outputs 3 Inputs 3A Fast Charging Power Bank for Samsung Google Pixel LG Moto iPhone iPad --- ## 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/585959795-portable-charger-built-in-cables-20000mah-power-bank-6-output](https://www.desertcart.us/products/585959795-portable-charger-built-in-cables-20000mah-power-bank-6-output) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-02*
