Leistung Satt!!!! Für Unterwegs in die Hosentasche stecken ist nicht :) zu gross und zu zuschwer. aber für Rucksack oder zum Laden im Auto kein problem. ### ⭐⭐⭐⭐⭐ Review *by G***I on 27 October 2023* Sono stati squisiti nel sostituirmi il prodotto, che per quanto robusto e potente di ricarica, era troppo pesante per me. ### ⭐⭐⭐⭐⭐ Review *by M***Z on 14 July 2023* En general muy satisfecho con el producto, ta un amplio margen de uso con la dashcam, con la que frecuentemente la uso en modo vigilancia o para cargar dispositivos. La única pega, que el tiempo para cargarla es muy elevado, eso que la estoy cargando con un cargador potente de 120 W. ## Frequently Bought Together - ROMOSS Power Bank, 40,000mAh 18W Portable Phone Charger with USB C Fast Charging, External Battery Pack Compatible with iPad, iPhone 15, Samsung, Tablet, Steam Deck - ROMOSS Power Bank, 30,000mAh Portable Charger with 30W USB-C Fast Charging for ipad, External Battery Pack with 3 Outputs& 3 Inputs for iPhone15/14/13/12, Sumsung and More (30000mAh) - ROMOSS 60,000mAh Large Power Bank, High Capacity Portable Charger 22.5W USB C Fast Charging, Long Lasting External Battery Pack with 4 Outputs & 3 Inputs for iPad, iPhone, Samsung, Switch 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.uk/products/366832514-romoss-powerbank-40000mah](https://www.desertcart.co.uk/products/366832514-romoss-powerbank-40000mah) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
