Works fairly well. Draws ~13-18mA depending upon voltage off the battery constantly. ~3mA of that is in the LED's (depending again on voltage) and the rest is just running the on-board electronics. I also wish the battery status led's were a) dimmer or b) turned off at night. I adjusted the internal pot so that the LED's turned on/off at more useful voltages (12.9V, 12.0V) The lowest LED cannot be adjusted (~9.2V). The unit will automatically disconnect loads at somewhere between 10.5-11V (which is nice for preserving standard chemistry batteries). Can't beat the price. Nice internal heat dissipator for the power electronics with proper thermal interface material. Nothing fancy but pretty well made.

It may be too early to write reviews but this review is just based on my initial observation. So far it worked as described without going into technical details. I think the setup is good for an in-expensive regulator. Instructions, clear. I like that it has a battery power indicator (3 LED's). Four star is because at night the LED lights are still on. it doesn't consume much power but still consumes a little even without a load. I have a harbor freight regulator on one of my setup and all the LED's will turn off at night (means no charging from the panel). This is just so inexpensive to pass up and try. After discounts on HF this is still about 9 bucks cheaper. If everything goes well, this will be a good solar car battery maintainer with a minimum of 15W panel. My setup for this is just a regular car battery, a 50W panel laying flat on top of my sunroom, wired with low voltage 12g wire and a 300w inverter (kinda like a UPS). I use some of the stored power just to light up my computer desk using 12v car LED lights. My other setups is another story (like you!-a mad DIY scientist). It did help power my Uverse UPS for modem and phone for an extended internet access, when the power went down.

I needed a cheap controller for a small solar panel and this one fit the bill. Initially I had an issue withe seller sending me the wrong product but they sent the right one out. Shipping took forever from overseas (wish I knew before ordering). The charge controller is fairly small and simple. It gives you a quick glance at state of charge for the battery, if the panel is charging, and if there is a load on the battery. Simple and effective. I almost like this one better than my other controller for my larger solar setup. This one is easy to use and straight forward. I love it.

This doesn't matter if you disconnect the charge controller after charging completes; but, either this model does not have a blocking diode or mine is broken, because my "conected" leds continue a weak glow after I disconnect the solar panel. I have ordered a second controller to test this problem; but, in any event, this is a great little package, especially the prong connectors and plastic shield cover. Those who complain about the "load" circuit not working probably do not know how load circuits work (only when there is no solar panel and/or when battery is fully charged). Check two controllers to verify before returning as defective. You need two for a backup anyway, so quitcherbit**in about buying a second one.

I received item before a lot other items I ordered a month ago from overseas. Pretty straight forward directions too. It's an easy & cheap way to keep your battery from dying when you have to leave your vehicle for a long period of time (i.e. airport, hiking or kayaking trip).

Good product the led display helps monitor and keep my back up battery ready to go. For the price yes No it is not for a full blown solar system but works well on back up power system I use. Yes would have liked different out put adaptor but any DIY experenced person can make their own to solve that issue.

I rated this at a 4 because 2 out of six I bought originally did not charge the battery in my solar powered large scale railroad signal system, however they are not expensive so I didn't whine to the MFG, besides they come from the Chicoms and I decided to not be bothered. They work well when they are working and I now have a couple of spares in case someone figures out how to fix one. I am satisfied with the product.
