But Voltage light is clear and soft. VCMAG **Q: Will this show the correct voltage on a Lifepo4 battery?** A: Voltage is voltage, yes it will read-out the voltage. NOTE- Lithium batteries discharge different then deep cycle or starter batteries. Lithium batteries hold the voltage at 12V (+/-) and don't drop from 12 until they are close to being dead. Regular batteries the voltage drops as it discharges and at about 10 VDC some things won't work any more because the volts is too low. This Socket shows the voltage dropping so you know what's happening. With Lithium it will show 12VDC and then very quickly drop from 12 to 8 (for example) and it's too late, you won't have the power to start an engine. If you are powering electronics, maybe this is fine, it just stops working and you'll know why. This socket will also show the power going to recharge the battery, with my engine running the read-out shows 13.2VDC, so I know it's recharging. **Q: Can this be used in 12v 4 wheeler outlet?** A: Yes, it can be used in 12V-24V vehicles ## Frequently Bought Together - 12V USB Outlet, QC3.0 Dual USB Fast Charger Socket with LED Voltmeter, 12V/24V 36W USB Cigarette Lighter Replacement, Waterproof Aluminum Car Charger Adapter DIY Kit for Car Marine Truck Golf Cart RV - APIELE 16mm Latching Push Button Switch 12V DC On Off Black Shell with LED Angel Eye Head for 0.63" Mounting Hole with Wire Socket Plug Self-Locking (Blue/Black Shell) - 100W+100W Amplifier Board with Treble and Bass Control, DC 9-24V, BT and AUX Inputs, 2.0 Channel Stereo AMP Board for DIY Wireless Speakers, Password Free (ZK-1002T) --- ## 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.hr/products/103056027-12v-usb-outlet-qc3-0-dual-usb-fast-charger-socket](https://www.desertcart.hr/products/103056027-12v-usb-outlet-qc3-0-dual-usb-fast-charger-socket) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-23*
