36 V 48 V bis 13,8 V 100 A 1380 W DC DC Abwärtswandler Spannungsregler mit ACC

I am really satisfied with this product so far, it charges my 5kwh battery during car drives. Looses a bit of power throughput when it gets warm, but still charges at least around 800-900watts continuous

good and fast communication, very friendly and helpful, fast shipping, good product

Good product, nice price.

All found in good order! Tnx

I recently purchased the Daygreen voltage converter, and it's been flawless. This has been more than enough to power all my 12V devices simultaneously without any issues. I've noticed that it has a high efficiency rate, up to 95%. So far, I haven't experienced any overheating problems

With the post office no tax but sending with DHL is chargeable, too bad

Works like a charm. Solid design and engineering. Nice low profile and easy to install. Good value for the price. Thanks so much!

Slim profile, high quality, and good price.

Top!

Works great! Appreciate the quick and easy process!

After sales service has been very good, I asked a question about product and had a quick response, including extra information about the product

Converter arrived in a reasonable time. Tracking information was sent and arrived with no damage. Unit works as advertised. Setup was easy to understand. I recommend this product.

I purchased one of these a few months ago for a van build, so I could use the 12v engine alternator to charge up my 25.6v lithium house batteries.

It does the job, puts out a solid 40 amps, reading 1100+ watts on my battery shunt. It also works well charging in parallel with my solar array, and a 30 amp AC charger.

It also automatically knows to only charge the house batteries if the car is actually running. If you turn the car off the charge stops too. You can also wire in a remote accessory enable switch so you can also disable it while the car is running too, or have peace of mind to know it's off when the car is off.

I'm buying a second one so I can charge my house batteries at 80 amps if need be. I was hesitant at first to buy 2 because the amps/watts for this unit advertised did not compute. But after buying 1 I can confirm it is a 40 amps 1168 watt unit that hits 29.2 volts and works great for charging my 25.6v lithium batteries.

Great little item, does exactly what it says on the box.
Thank you.

Hands down the best Voltage converter on the market!!!!
