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 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!
I made my own "power bank" with low voltage alarm for my LiPo batteries. See pictures.
I'm mounting this in an outlet for my battery backup system. Our power goes out a lot. I wired my house for 12 volts and this will make it easy to charge my phone and other things. I added a switch so it doesnt use power when it's not being used to charge.
muy buena compra
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.
good value for money Very useful for diy projects.
Good value for money. Not yet tested
Seems to deliver stable 5V (approx) power under a wide range of input conditions. However, the efficiency is not particularly high at low currents, as would be expected. Attached is a table of efficiency calculations using my non-calibrated equipment. No load current is 5mA which is a bit high for my liking. John from Ontario, Canada
veio embalado de uma forma forma simples, mas chegou intacto e funcionando bem, só testei com 12v. vou testar com fontes de outras voltagens para ver se continuar carregando bem. carrega rápido. satisfeito até agora.
