I've used DROK to put usb charger ports in boats, bikes, house lamps and a car. The house lamp was the hardest; I used a power brick laying around, but fit was an issue. We added a 24x7 power port to a BMW whose 'smart bus' seemed designed to drain the batteries of all non-BMW branded devices. Wired directly off the battery to a DROK converter supplied port laying inside the (armrest) bin.. problem solved. The owner leaves his cellphone in the vehicle and uses the bluetooth link to the house phone. And the Buck converter, what I've noticed, at full charge it gets pretty warm, too warm to poke around with your finger checking how hot it is... so I added a heatsink to the chip and venting to the case. Supplying about 10W flat out, it is way cooler than I'd have believed. At maintenance charge it is essentially warm. These things are efficient! I don't notice a difference on my trike after a week leaving the power on to the (turned off) LED lighting. On bikes and boats worry about ventilation and waterproofing, as in both places nobody remembers to charge devices until they really need power. I've put in 5 of these and made portables for friends who want to be able to plug into 12v ports. We have yet to get a failure other than when I connected it so sadly wrong. I like the display because to me it's worth the price to be able to verify performance. It also means I can leave my DVM packed. The display is certainly accurate for its use, maybe 0.1V or so, and you can calibrate it if you want to feel better. This is not a laboratory supply; you don't get that for $10. I'm very happy with the value. In fact I worry a bit about the cutthroat Chinese business model. If they can resist the plunge to the bottom on pricing, certainly DROK could be another name like Westinghouse (etc.). It can take a while to get the order. I usually get it within 10 days or so, which is astonishing. Then (likely customs) happens, and it takes weeks. DROK supplier can hardly affect that, so be patient. A part order from Detroit to Louisville could take 5 days not that long ago.

Works great, display is accurate according to my DVM
I used this dc to dc to convert 24V to 12V for a spindle controller on my CNC. The product worked exactly as advertised displaying both input and output voltages accurately. Voltage adjustment was very smooth and accurate. I would buy this again without hesitation.
