Review on 💧 Waterproof 24V to 12V 40A DC/DC Voltage Converter Regulator - Cllena 480W Buck Transformer by Michael Boyd

My Bluetti AC200 and AC200P "solar generators" charge with 100 watts from a 12v source OR 200w from a 24v source but it takes forever to charge the Bluetti with charge 100 watts. charge if necessary. The large LiFePo4 battery is charged with 1500W of solar power, so it was plenty. In short, it worked like a charm! This device provided the Bluetti with 204 watts of 24vdc to keep it charged while drawing 16.8 amps from the 12 volt battery. I've been using it this way for several months with no problems and I can attest that it works great; Just make sure your wiring from the battery to the 12-24v amp is adequate. I recently upgraded the battery to 24V so I just bought the 24V to 48V version of this product so I can fully charge the Bluetti. 700W at 48V from a 24V source. Since the device is rated at 960W (20A), I don't expect any problems at all. I will add a review for this product once I have had it for a few months. Highly recommended!
