Easy to use with existing Optimate product cable. Great. I can now keep my mobile devices charged when out on my motorcycle. ### ⭐⭐⭐⭐⭐ ... *by T***E on 16 April 2026* Ok ### ⭐⭐⭐⭐⭐ Perfect for my needs *by A***S on 10 September 2025* Very handy if you have bags on the rear of your bike and the USB port is under the seat. All I have hanging out from under my seat is my SAE charging port. If my phone needs a boost I can now plug in the charger without having to remove the seat. Although it states that it will not drain the battery, I don't see why it needs to be connected long term in my case. ## Frequently Bought Together - Tecmate OptiMATE USB O-100, Combination 2400mA USB Charger and 3-LED Battery Monitor, With Vehicle Battery Protection - Optimate cable O-01, ring terminal harness, powersport - Tecmate TecMate OptiMATE 1 DUO, TM-409, 4-step 12V / 12.8V 0.6A battery charger & maintainer --- ## 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/260029107-tecmate-optimate-usb-o-100-combination-2400ma-usb-charger-3](https://www.desertcart.co.uk/products/260029107-tecmate-optimate-usb-o-100-combination-2400ma-usb-charger-3) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-09*
