Never charge the battery. Keep good air convection. Never reverse the polarity. Use the enough big cable to avoid the voltage drop. Specifications: 1. Full power and stable current output, non-isolated module. 2. Industry grade DC 12V to DC 19V 10A 190W step up converter, efficiency up to 95%. 3. 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. Input Rated Voltage: 12V DC Input Voltage Range: 10V-16 DC Output voltage: 19V DC Output Current: 10 Amp Output Rated Power: 190W Enclosures: IP68 Case Operating Temperature: -40~85°C Review: Worked when I tested it. - I bought this to try and charge a power station faster from a 12 volt source. It works. Seems to give about 184 watts into the power station at 24 volts at 8.8 amps. There is a loss in the conversion. By my math the converter is 94% efficient. I lose another 6% from the charge controller when plugged in. I was getting 205 watts out of the battery, 194 watts out this converter measured by a watt meter, and seeing 184 watts on the display. So, a total of about 89% efficient when all is said and done due to loses on converting and the charge controller. Will charge faster than the regular 12 volt input. It also allows me to add a 12 volt battery to the power station and double the watt hours for the power station. I tested it overnight and it took about 956 watts total out of the battery to keep the power station at 100% over a 8 hour period. Review: Good for step up. - Worked well, does not work well if you swap the voltage around. I used it to step up the voltage in a spare lithium battery that was 12 volts so it could power my Bluetti which only accepted a minimum of 16 volts. Wired some standard solar MC4 connectors to it but you can use different ones. ## Features - Wide DC boost converter regulator DC 12V to DC 24V 20A 480W - input voltage range DC 11-16V; output voltage: DC 24V(non-adjustable); output current: 20A(max.); output power 480W. - 5 Safty Protections - Over-load, Over-current, Over-temperature, Short-circuit, Over-voltage; Auto-recovery when device is back to normal operating, over 100,000 hours lifetime. - Wide application - fits for car, truck, vehicle, boat, electric bike, bus, cmb, club cart, LED strip lights, display moniter screen of taxi, car radio audio device, LCD TV, DVD, IP camera, speaker system, GPS, air-conditioner, electric fan and any 24v DC appliances. (Note: Never connect to solar panel or wind turbine.

Wires input 10AWG, outout 12AWG. If still any question, please contact us. **Q: What is the minimum load required for the converters (both 10A and 20A versions) to operate properly? Also would running without load cause damage?** A: Dear Sir/Madam, Thank you for your question. 10A versions long-term working current is about 7A. Limit resistive load. 20A versions long-term working current is about 14A. Limit resistive load. Running without load will not cause damage. Hope the answer can help you. If any question.please contact us.thanks. **Q: Can this be used to charge a 24v cart battery from a 12 car battery** A: Dear Sir/Madam, Thank you for your question. Sorry, It can not be. This is for voltage booster, it is not for charging. Please note it. **Q: For a desired 8a/24V output, what would be the over all power loss (how many input Watts needed for 192W out)?** A: Hi Dear Customer, Input voltage range DC 11-16V; output voltage: DC 24V(non-adjustable); output current: 20A(max.); output power 480W. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked when I tested it. *by J***S on September 24, 2024* I bought this to try and charge a power station faster from a 12 volt source.

I used it to step up the voltage in a spare lithium battery that was 12 volts so it could power my Bluetti which only accepted a minimum of 16 volts. Wired some standard solar MC4 connectors to it but you can use different ones. ### ⭐⭐⭐⭐⭐ Update: works but check your amperage *by B***N on April 26, 2021* ***Updates further down*** I purchased this device because I acquired 24v ARB Twin Compressor gently used. Problem was, my Jeep is a 12v system so obviously that won't work. There was very little help on the subject until I came across a short thread on a forum that addressed exactly my problem and referenced a device almost identical to this one here. I took the gamble and gave it a try and voila! I know can use this very expensive compressor on my Jeep! I was so thrilled to see it power on and run! I have not full completed my install to where eI can really test this thing in the real world environment to see if it can handle a long duty cycle, but first test run was a success! I ran this test last week so at this date, 4/26/2021, it appears to be a success, I will come back and update once final install has been completed! Update 9/21/21: this item works to step the voltage up to 24v. But amperage limited me from using this for my application. The unit powered on fine and tested fine. But I’m real world application, under load, it could not draw enough power due to amperage limitations. Check the amperage draw of your device before purchase. Otherwise, it’s legitimate. ## Frequently Bought Together - MGGi Waterproof DC/DC Converter 12V Step Up to 24V, Boost Converter 20A 480W Voltage Regulator, Power Adapter Voltage Booster,Power Supply Module Boost Transformer for Car Truck Vehicle Boat - Victron Energy BatteryProtect 12/24-Volt 65 amp - WOHHOM 30A 40A 50A 60A 80A 100A 150A Audio Circuit Breaker Auto Car Stereo Inline Fuse Holders Inverter, Manual Reset 12V-24V DC for Automotive Marine Boat Audio System Protection (20A) --- ## 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/175117371-waterproof-dc-dc-converter-12v-step-up-to-24v-boost](https://www.desertcart.hr/products/175117371-waterproof-dc-dc-converter-12v-step-up-to-24v-boost) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-23*
