I bought a defective connector and wondered why using it with the adapter makes the led turn off. Turns out it has a great short protection and it worked just fine the day after I realized what's going on. It still gives 8.4V with no problem and charged my batteries. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars I use this for charging batteries for my VICMAX A60 headlights. *by H***H on Reviewed in the United States on August 19, 2021* I use this for charging the battery packs for my VICMAX A60 headlights for my Zero 10X electric scooter. It was handy that it came with the tip attachments in case I ever want to use it with something else that happens to have a similar power input requirement. But I was lucky to not need any attachments for my battery packs so I don’t have to worry about losing a needed attachment. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/236302698-8-4v-1a-power-supply](https://www.desertcart.co.uk/products/236302698-8-4v-1a-power-supply) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-04*
