👌

Used this to power a 900W JL audio amplifier and it works great - no additional hum or noise in power supply. Voltage stays consistent

Teljesen meg vagyok elégedve vele köszönöm szépen 🙋

The regulator works fine, but the processing and handling time between ordering and receiving the product could benefit from improvement.

Working like a champ

So far i'm returning costemer and very happy with postages
and quality.
Thnx

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.
