Spec: 12V to 48V 3A Verified Purchase
I used this to step up 12v for my Starlink Mini. Works like a charm. After a full day of using the unit, i noticed no noticeable heat from it. If you're looking to power Starlink with this item, it will work wonderfully.

Spec: 12V to 48V 3A Verified Purchase
Installed this in a DC battery/solar box project, fed by DIN MCB, leading to 3321 plug. Powers my Starlink Mini reliably off of 12V (actually 13+ LFP) battery and solar.

2025-11-20 | United States United States
Spec: 12V to 48V 6A Verified Purchase
So far has worked well after 1 week of almost continuous use.I installed this step up converter in my Camper Van to run my Starlink to its on rocker switch via my 12v system so I could avoid turning on my converter. The unit stays at a good temperature, and makes no noise. Wires fit well into my Wago lever nuts and all seems good.If I ever need another Step Up Converter, I would definitely consider this brand and unit.

DC to DC for Charging
2025-01-21 | United States United States
Spec: 12V to 48V 6A Verified Purchase
This delivers around 220 watts of charging to my Ecoflow River 2 Pro from my truck's 12V supply. When the battery is charging off the cigarette charger, it maxes out around 95W so more than double the speed. Unlike some of the other DC-DC converters I've read reviews on, this unit doesn't even get hot delivering the 220 Watts.

Great to upscale two 24 volt 200 watt panels to 48 volts keeping them in parellel to avoid confusion as to max voltage on other devices
