Depvko [2021 Upgraded] 30A Solar Charge Controller, Black Solar Panel Battery Intelligent Regulator with Dual USB Port 12V/24V PWM Auto Paremeter Adjustable LCD Display

Had to replace an old charge controller. This one is nicer and has a usb charge port.

I am using this device along with a 100 watt Coleman panel I bought from Canadian Tire that came without a charge controller (thanks for nothing Coleman! 🙄). Works exactly as promised/described on Amazon's listing. I like that I can configure the output power level to the battery, the charge level and the cut off (battery full) level myself (for now I've left them on the defaults). Very simple to use & adjust.The accessory 12v power output connector is an interesting idea, but as another reviewer mentioned, it seems to come on and off on a whim. I was under the impression from the instructions that it would turn on when the panel was inactive (at dark), and back off once it was charging again (when sunny) when set to 00. But when I tested this by disconnecting the panel to simulate dark, it came on and stayed on after the panel was reconnected. Weird. There is some kind of timer control to it, I didn't really explore it much more, but you can set it from 00-24. Does it just count time down from the setting once you set it? Who knows, there is very little information about it in the instructions. (As is typical with Chinese products purchased on Amazon).The USB outlets charge at a reasonably fast rate (my Samsung phone was at 39% & claimed it would be fully charged in two hours).The only other concern I have is regarding those very USB outlets. They are active even when the panel is disconnected (ie: when only the battery alone is connected). This tells me they are drawing and converting 12v from the battery to 5v for the USB outlets constantly. I suspect this could lead to a slow vampire draw on the deepcycle battery when/if the system sits idle without any panel connected to it or at night. But if you always have a panel connected, that shouldn't really matter - the daytime solar charging would likely more than make up for it.I was getting 13.1/13.2 volts into my battery under a heavy overcast sky late in the day, my panel was putting out more than 18 volts at the time.I definitely highly recommend this simple little controller, I'm completely satisfied for under $20 (including taxes).

Funciona bien a secas, puntos en contra de calentaba y bajaba la energía que mandaba a la batería, la otra contra es que sus contactos son endebles y los cables que llegan del panel con el movimiento se aflojan y sueltan, soporta el panel de 390w

I wanted to set up simple solar lighting arrangement in my garage. I already have a similar set up and find these controllers good to ensure I have a charge and control the input from the panel. It is working really well and it does not cost too much so all good so far.

Bought this to use with a solar charged battery in my garden shed. The regulator that came with the solar panel just dealt with charging the battery and had a couple of lights to let you know it was working. This one has a digital display showing voltages, battery types and output timing.I have the output, landscape lights, set to go on at dark and off when it gets light. I use one of the USB ports to power a security camera.Installation and connection was easy. Instructions a little cryptic but can be figured out.
