Boost Voltage Converter, DROK 600W 12A Dc Boost Voltage Converter 12-60V to 12-80V Step Up Power Supply Transformer Module Regulator Controller Constant Volt Amp

Preliminary testing suggests a FANTASTIC product. My project just involves using my old Dell laptop in my car powered by a separate 12V AGM battery. The Dell requires a 19V input. Although the setup works, the laptop doesn't know what power source it is because it is not receiving the ID information from the 3rd wire inside the cable core. I will need to rectify that by dismantling the old power supply and finding the chip or eeprom that stores that information for the laptop. For the moment, the laptop is not going to charge the battery 'nor operate at full processor speed while hooked up this way but that's OK :) Thank you DROK.

Simple to use and set-up without too much techno knowledge. I used a set of these to power some 100 watt LED's and they work just fine, actually too good. I attached 2 100 watt LED's and the heatsink still did not get warm to touch with 3 amps running through it. The build quality is good and the directions for adjustments are easy to follow. The only thing I found is that the screw terminals for the input and output wires seem a little loose, but not enough to cause a connection problem, at least not for me. Have not been able to really push the limits of this converter, but that is good, gives me room for adjustment.

This item works perfectly! Here is my application and how I use it: I have an RV that has been converted to handicap use. There is a power lift chair that reclines, and also will lift the disabled person to a standing position. It has a power supply that only plugs into a 110V AC wall outlet. The power supply puts out 29V 2A DC to the chair. My problem is that the whole system is horribly inefficient. I had a 600W DC to AC inverter to go from the 12V RV batteries to 110VAC, and then the power supply converts from 110V AC to 29V DC. So many power changes and inefficiencies! With this DC-DC step up converter, I simply took the 12V wires and plugged into the input side of this magic device. I used a voltmeter on the output side and turned the little screw until it read 29V. Then I plugged the chair directly to the output side. It works perfectly to step up the 12V batteries to 29V. Simple, clean installation removes all of the clutter of wires, transformers, power supplies, and junk!

I purchased this to use with my 48v wifi system. After a couple of months I was rebooting alot. when I checked the DROK it is registering 20v no mater how much I adjust the pots it doesnt do anything so I put it aside for a couple months and just yesterday I thought I would check it again. This time it registered at 80v and when I tried to adjust the pots it went again back to around 20v and thats it. I see lots of people have had good luck with this unit I quess I am just not one of them.

Nice unit, easy to connect and works good. I use this to step up 48 vdc solar panel to 56 vdc to change a lithium battery in my ELF from OrganicTransit dot com It works good. There are 2 adjustment screws but no notes on which is voltage and the other amperage. There should be at least a few basic notes with it. But it works good even in the heat of the Phoenix, AZ area.

This is a great product with a lot of power behind it. I am running two of these off of a 12VDC 30amp LED driver. Each one runs a high power 150 Watt multichip LED that draws 4 amps at 44 volts. The beauty is that it also has a setting for the voltage and the amperage so that you can set the current you want and not have the LED at 100% power consumption and should last a little longer. Seems very well built.

Works great! Output voltage is rock steady and can be set with a fair amount of precision. It does dropout if input and output voltages are far apart, (more than 20-25 volts). It can be adjusted to work with low inputs and work well, it's just a problem if your input is varying that much, which it shouldn't in most systems. It's a little large and the heat sink maybe overkill for all but the most demanding systems, but it's nice to know it's there if you need it.

I'm still in the prototype phase, but this has been rock solid for me. Right now, I've got it dialed in to drive a 100W LED, and it handles that like a champ (as is to be expected from a 600W boost converter). I wish there was some kind of conformal coating on it, though, but for the price, you can't beat it. I'm not sure what the jumper in the center of the board is, though. I'm not brave enough to jump it...maybe someone can clue me in on what it does?

Excellent boost converter. I use it to power a Cree XHP70 LED. Can send over 40W to the LED no problem without getting warm. The constant current/constant voltage function works wonderfully. I can set my voltage to a safe limit above the normal operating voltage of the LED (13.5V for 12V LED), then just use the current adjustment to get a current-controlled LED. A great addition to any hobbyists workshop. The one thing that would have been nice is to have thumb-adjustable C/V knobs, but this would likely be a con for most people. The need for a screwdriver prevents accidental change of power output, and reduces footprint.

Nice product, as are all I have bought from you. Although I like the numerical display version more. Aside from the graphical display, the heat sink placement on this unit is kinda limiting as far as mounting options. I do like how it is a better utilization of board space, but.... I do like your products, though

12amp X 12vols = 144watts alors vous devez y pensé !...... Mais très précis et controle d'ampérage très commode. Merci

Not good for HF radio. Creates too much noise from the switching supply. It may work well for other applications but not for HF radio. My specific use was for use with the Elecraft KX3 Portable transceiver. VE7CN

This unit does boost if the input voltage is over 12V. The 600W rating is only if the input voltage is closer to 60V. DROK should offer a buck version of this unit. Note that the constant current feature does not work.
