Aideepen1200W 20A DC Converter Boost Car Step-up Power Supply Module Adjustable Voltage Converter 8-60V to 12-83V

Works perfect for my need, boosting voltage from 12.3 to 14.5 and holds it right on the number when loaded. I'm not loading but about 8 amps that's only at start up after that to 2.5 continuous.

The electrolytic capacitors on the output side are severely dented. So, badly that I am worried about turning it on anyways. It seems to me these dents are NOT from shipping it as the packaging material does not show signs of abuse. These were damaged before they were shipped! I will replace the capacitors because I am in a rush to deploy it.Follow up: They sent me a new unit that was in a better shape. The supply worked as advertised. Thank you for the good service.

using this to charge a 60V ebike battery from a 12V automotive source. i tried the 1500w and the 900w drok and this is the only device that worked for me. recharges battery at 3A max (user adjustable) until 67.2V limit (user adjustable) is reached, then holds voltage at 67.2V as current declines. i will probably add a quiet 50mm fan since the heatsink was approaching 130f at 70f ambient under this load. the unit has a 2-pin fan connector and holes tapped in the heatsink to allow for fan installation.

holy crap its still working special note on this.Do not have under a full load while turning input on (input current can spike to 100 amps and the main mosfet blows out)Avoid setting low voltage protection below 11.2 volts (see line above)Just because the low voltage protection light is on does not mean it is not working at all but just at a lower rate (less heat)Be sure to use both input connections for + and - at a high current output like 10 amp or more (one can result in input post melt down)At max current output keep an eye on your input wires and make sure they dont melt down from 40+ amps of current (yes 40+)If you want to keep this working at a max constant current replace the heat sink with something 2x the boards size a 200mm x80mm x40mm would do the trick and use a fan youll need it.I bought 2 of these from ebay and had a problem from day 1 with them and had to replace the main mosfet 3 times in both of them after the 3rd time they blew for no good reason i scrapped them and bought this one but those 2 did teach me a lot on some dont do's.I use this on low sun days for solar energy charging my Lithium battery packs low sun days do not produce enough voltage to get the packs charged so gotta use something and this works just fine as long as they are kept cool (below 70C) and not under a load when i turn on the input and have the low voltage setting no less than 11.2 volts.The Default heat sink is most certainly not enough the main mosfet and the other mosfets produce to much heat at a constant high current (around 22amps) and conducts the heat to the board heating every single component that is on the board so try to keep it under 70C to avoid any hiccups and small component fails. Thats be best advise i can give for these.Update 11-11-18 BLOWN yep not working anymore these things are totally NOT RELIABLE im so fed up with having to repair these things I put a shottky diode on the output to prevent it from getting reverse current from being hooked up to a battery to charge them so far its been stable but at a loss of 3 amps charging current reducing it to 17 amp max constant.

I am using this product to solar charge an e-bike battery. The solar panel puts out 20-22 volts at 5 amps and I set the DC converter for 53 volts. I use a "Crystal Lite" drink mix container to slide this converter in and since the container is clear - I can see the small LEDs on the DC converter. This also beats the "made for" box cost. The heat sink fins stay on the outside. This DC converter can handle more power than what my portable solar panel can give but, to just wheel out somewhere and set up a charger - this does fit in a backpack.

I figured I got a bad one. The second one came no were near rated specs. The trim pots are very difficult to get a reading. Once you get a reading and you then move to slow movements to fine tune settings never hold.So I wasted two purchases for paper weights. I don’t want to keep returns of products poorly created to Amazon because I have gone through several products of cheaply made products from the same place. Don’t want a rep of constant returns so I eat it.

The media could not be loaded. I don't know if I would use this to pull 20 amps on the input side which I'm currently trying to do with a car battery supplying power to it cuz it's going to be used in a mobile application cuz even with my testing I'm doing at 15 amps coming in on The low voltage side at 12 volts and output side running at 65 volts charging a battery. This thing is getting pretty warm with no active cooling. Something to consider if someone is trying to actually move some serious wattage with this thing. I'm assuming the conversion efficiency goes up when you have a closer supply voltage to your output voltage, but most people are going to be running this on a 12 or 24 volt input most likely and stepping it up from there. I would imagine you would be able to push more current at higher efficiencies if you were going from 12 to 24 instead of 12 to 64 like I am.
