Dual USB 9V/12V/24V/36V to 5V Converter DC-DC 3A Step Down Power Module
A part of the review has been auto-translated.
I got my item and it meat the specifications but is a bit sad. Mine came without the USB port. (HAVE YOU EVER TRIED TO GET AM ITEM REPLACED WITH BANGGOOD. Life is too short). So I will just suck it up. Hay it works but at 2 amp seem very low in power. It is more like 0.5 amps. It would be nice to know who else have issue with this item. Sadly, this review, will never be POSTED because BANGGOOD only posts the GOOD!
It came packaged in a simple way but arrived intact and working well, I only tested with 12v. I'll test it with sources from other voltages to see if it keeps loading well. Load fast. Satisfied so far.
It's working OK
took over a month to arrive.
fast shipping
directly connected to solar panel and working great
I ordered a bunch of these to install in cars. They are based off LM2596, which is rated for 5V 3A output. I think the price is great and function is perfect. Happy with the order.
Quite nice, will handle 2 amps and more (total), but needs extra cooling. I glued little radiator to dissapate more heat. I wouldn't risk going for full load 24/7, could overheat. Other than that doing grat job charging phones, tablets, etc. Single socket will give you 1.5 amps max because theres no resistor coding. Add some resistors and you can enable apple type output for example.
I made my own "power bank" with low voltage alarm for my LiPo batteries. See pictures.
Good value for money. Not yet tested
