Die-cast aluminum shell, epoxy potting, cooling by free air convection; Waterproof level IP68 and anti-shock protection. 4. Protections: Over-current, Over-voltage, Over-temperature, Over-load and Short-circuit, auto-recovery when device is back to normal operating. 5. Certificates: CE/RoHS, 1 year warranty, lifetime up to 100,000 hours. Package included: 1 x DC 8V/40V to12V 10A Converter Questions: How to choose the correct current for loads? For example, if the max current of your load device is 10A, then choose 10A/0.8=12.5A at least for resistive loads according to international standard. If the load device is motor or compressor, then you may choose 10A/0.5=20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current. Review: works as advertised - I decided to power a few electronic devices on my boat with 12 volts as opposed to using the wall wart power chords that depended on 110 volt AC. A lot of devices, like my router, mini pc, disk drive enclosure, etc. use 12 volts. The one issue with using the boat's 12 volt system to power these devices is that the actual voltage can get well over 14 volts when the boat's batteries are being charged. Im not sure the electronic devices can tolerate this higher voltage. This device takes in the voltage of the boat's 12 volt (nominal) DC system and outputs 12 volts. It arrived promptly, was easy to install and works fine. Review: Great product - Great product long lasting easy to use ## Features - Input voltage range: DC 8V-40V; Output voltage: DC 12V(non-adjustable); Output current: 10A; Output power 120W. - High conversion efficiency: Synchronization rectification technology-multiple intelligent protection function with high conversion efficiency and stability. The conversion efficiency may reach 95%. - Protections: Over-load, Over-current, Over-temperature, Short-circuit, Over-voltage. - Aluminum shell and silicone sealed design: Waterproof, Anti-shock, Anti-humidity and Dust-proof, more durable. - Wide application: Large trucks, Golf cart, Club car, taxi radio, emu, car audio, LCD TV, advertising screen, LED strip lights, monitoring system, electronic systems and DIY etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08KZPXK63 | | Best Sellers Rank | #45,133 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #172 in Power Converters | | Brand | Cllena | | Color | Grey | | Customer Reviews | 4.6 out of 5 stars 119 Reviews | | Input Voltage | 40 volts | | Manufacturer | Cllena | | Mfr Part Number | DC84012-10 | | Model Number | DC84012-10 | | Number of Items | 1 | | Number of Outlets | 1 | | Output Voltage | 12 volts | | Power Source | DC power supply | | Total Power Outlets | 1 | | Unit Count | 1 Count | ## Product Details - **Brand:** Cllena - **Color:** Grey - **Input Voltage:** 40 Volts - **Output Voltage:** 12 Volts - **Total Power Outlets:** 1 ## Images ![DC 8V-40V to 12V 10A Automatic Buck Boost Converter Step Down/Up Regulator Voltage Reducer Converter Waterproof Regulated DC Power Supply for Golf Cart Club Car LED Light - Image 1](https://m.media-amazon.com/images/I/71jQ3A+pljL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ works as advertised *by J***N on January 1, 2025* I decided to power a few electronic devices on my boat with 12 volts as opposed to using the wall wart power chords that depended on 110 volt AC.

So much draw that it shut down my outboard motor for safety reasons. The motor’s charging system detects high output. I wanted to maintain a constant 12vdc for the depth finder and it worked but with motor shutting down I couldn’t use regulator. Kept for an unknown future project. ## Frequently Bought Together - Cllena DC 8V-40V to 12V 10A Automatic Buck Boost Converter Step Down/Up Regulator Voltage Reducer Converter Waterproof Regulated DC Power Supply for Golf Cart Club Car LED Light - Cotek SP-700 Pure Sine Wave Inverter with Dual GFCI 120VAC 12VDC 700W (SP-700-112) --- ## 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.fr/products/251540641-dc-8v-40v-to-12v-10a-automatic-buck-boost-converter](https://www.desertcart.fr/products/251540641-dc-8v-40v-to-12v-10a-automatic-buck-boost-converter) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-18*
