DC/DC 12V to 24V Boost Converter 20A 480W Step Up Voltage Regulator Module Car Power Supply Voltage Transformer (Input 10V-16V)

I had a 24v Webasto i needed to run off 12v, worked perfectly.

My Bluetti AC200 and AC200P 'solar generators' will charge at 100 watts from a 12v source OR 200 watts if from a 24v source. I had a LiFePo4 280ah 12v pack set up that has gobs of power but would take forever to charge the Bluetti at 100 watts. I figured if I could boost the voltage from the LiFePo4 pack to 24v, then I could supply the Bluetti with 200 watts of recharge when it needed it. The large LiFePo4 battery pack is charged by 1500w of solar so it had plenty available. In short, it worked like a charm! This device supplied 204 watts of 24vdc power to the Bluetti to keep is topped off while pulling 16.8 amps from the 12v battery. I used it like this for several months without a problem and can attest that it works great; just make sure your wiring from the battery to the 12-24v booster is of sufficient gauge. I recently upgraded the battery pack to 24v so I just bought the 24v-to-48v version of this product so I can charge the Bluetti at a full 700 watts at 48v from a 24v source. Since the unit is rated at 960w (20a), I do not expect any problems at all. I'll add the review on that product once I have it for a few months. Highly recommend!

The device works great. 12v to 24v more than handles the load.

I use rechargeable electric weed eaters to trim and edge my yard, and a vintage 2009 electric Neuton EM5.1 Mower to keep it cleanly mowed. But the OEM two 12V 10Amp sealed lead acid batteries were woefully inadequate for the task, and I didn't really care for my hacked version with two 12V 21Amp sealed lead acid batteries that I intentionally broke open and flooded with standard battery electrolyte solution, to prevent the cells from drying out, which although a great improvement, weighed 25 pounds for the batteries alone. But when I got my hands on a state-of-the-art LiFePO4 12V 32Ah (384Wh) Rechargeable Battery (batteryspace.com item#26650), weighing only 9 pounds, I made it nest securely into the Neuton EM5.1 mower, and then mounted the Cllena 12VDC to 24VDC Boost Converter 20A 480W Step Up Voltage Regulator Module (see photo). This lawn mower finally works like should, thanks to 2020 technology. The 24V / 32A / 768 Watt 4300 RPM electric motor that direct-drives a sharp, 13.5-inch sharp steel cutting blade (6.75-inch radius) typically draws about 4 - 5 Amps when idle, and about 10 Amps (240 Watts) when mowing, and about 15 Amps (360 Watts) when mowing deep grass. I highly recommend this excellent electronic device.

It works very will on the 24 volt espar heater:: that’s in a 12 volt service truck :: witch the heater pull only 4 amps
