I was getting no power whatever from the usb ports. Not necessarily a deal breaker unless one is planning on a usb powered fan to keep system cooler.The ports for the wires are very small for the amperage covered by the controller, so this would be the real deal-breaker.

Using this controller for my communications field kit, and it's doing fantastic! I've got a few different battery types, tested flooded, lead acid, and LiFePo4 and all worked perfectly. Solar hookup was dead simple. I've added some PowerPole style connectors to make the hookup plug and play.Used this during a recent outing to keep batteries topped up, and I'll probably end up using it during our ham radio club's field day event this summer to do the same!

I use this to control my setup on my enclosed trailer with with the deep cycle batteries and charging panels on the roof. It's been doing its job and haven't noticed any overheating or other issues. Seems to be built well and it's fairly easy to install. Priced competitively 👍

At first, I had a little trouble getting this charge controller to connect properly to a solar panel. I swapped out the connector and was able to make a solid connection. The operation of this is really no frills. There are two SAE electrical connectors, one for the battery, one for the panel. I was able to charge a 12V LiFePO4 battery with it as a test, and it charged it without any issue. I was using a 18V, 25W solar panel and it had no issues with connectivity. I'm not a huge fan of these connectors, and would much rather prefer a terminal connection, so the wires are a bit of an issue for me. This is especially true if you are trying to save space in a smaller weatherproof enclosure. Overall, this is not a bad option. It works and it is small enough for many different types of projects.

Standard solar charge controller, works good! Display is not backlit. USB and voltages look good on load. I like the case design.

Here, we have a 20 Amp 12 or 24 volt solar controller. It is useful for several battery types like AGM and LiFePO4 batteries. With a 20 Amp rating, this will pair well with solar panels up to 200 watts. It will also select 12 volt or 24 volt systems automatically. I used SAE pigtails to connect wires to it's screw terminals, so it can just be plugged in or unplugged. This controller is just a PWM (Pluse Width Modulation) type controller. Meaning it is not as efficient as an MPPT controller. It is fine for smaller solar setups like RV's and tiny homes. However, it may be better suited than an MPPT in a hot or warmer climate as well. With a readable display and easy connection, this is a fine solar controller and works well.

Much better quality then the cheapo 10.00 ones all over the place ... knocked one star off tho because this particular unit is quite a bit bigger then it needs to be there is a good almost inch on each side of jjst completely empty dead space for absolutly no reason

This controller has worked great for a couple of weeks. It was easy to set up for a 12V 12Ah lifepo4 battery. The buttons are easy to use. The directions were also easy to understand.I used it with 25w solar panel, the 12V battery and an intermittent 12V 5A load. I tested the usb ports and they both were 5A2V as stated. The wiring was easy to connect with nice spacing between terminals.
