12v 5a battery charge
Product arrived in perfect condition. I have only used the charger once to charge a 12v 30ah DC House battery and the charger is simple to use and charged the battery in 5-6 hours which was the time frame that was expected. Will give a further review at a later time after the product has been used repeatedly to give a fair assessment. As of now, the initial impression of this product is great.

Works well, good features, thin wires
This charger seems to function very well – the operation is simple enough that you don’t really need the manual unless you want to use it in one of its special modes ((restoring Lithium or Lead Acid batteries that have been over depleted). It comes out of the box set for Lithium batteries but pressing the “Mode” button easily toggles it to AGM and then Std battery charging profiles. Then connect the leads and off it starts. Watching the display, it flashes between showing the current charging voltage and the charging amperage, showing a max of 5 amps. I tested it on the 3 year old battery on our Mazda CX-5 (notorious for eating batteries and having a large parasitic drain while sitting). I saw the charger immediately detect the State of Charge based on its voltage (flashing the 80% bar) telling me that the battery was somewhere between 61% and 80% charged and go into bulk charge mode at 14.5v and the full 5 amps for about 20 minutes. Then when the SOC indicator started flashing the 100% bar (indicating it was between 80% ad 100%) I saw the charger switch to Absorption mode, the voltage dropped to 13.9v and the amperage dropped to 2.4 amps. I saw the amperage constantly adjusting based on apparent feedback it was detecting. Finally it went into “float” mode at 13.5v and between 1 amp and 1.5 amps. Based on what I saw, the charger seems to work very well and follows a more sophisticated charging profile that my old dumb analog Craftsman 10 amp charger (the big box that hums very loudly when running).

One of the things I really like about this charger is that it automatically switches to “standby mode” when it is done charging. This will be perfect for my Jeep, which is not a daily driver and really only gets used for trips to the back country and often has a dead battery because I forget to start it and drive it for weeks at a time. I also like that this charger comes with two sets of leads – one clip on and the other that can be hard-wired to the car battery. There is an SAE connector to switch between the two types of leads, so in theory you could leave the hard wired leads connected to one car and then use it with other vehicles with the clip on leads.

My main complaint about this charger is that the wiring is VERY thin and cheap feeling. The insulation is that stiff sort of shiny vinyl that is prone to cracking when it gets old and the gauge of the wires is quite thin when compared to brand name chargers like a NOCO. Even the 110 AC cord is very thin – it feels like a cheap lamp cord. I’m sure that for the max 5 amps this draws both can handle the wattage, but they just feel cheap in the hand.

The unit itself is solid, well made and heavy for its size with a clear bright display and very simple operation.

Great value, brought my dead battery back to life
I bought this because my car sat unused for a while and the battery completely died. The DC House 5A charger worked great and brought it right back to life.
Overall, it’s a great deal, but I did notice a couple of minor things. The clamps are a little small if you are trying to connect them while the battery is still hooked up to the car. Also, you have to press a button to see the charge status, which is a bit annoying but not a dealbreaker. The manual is fairly simple; it could be more detailed, but it answers basic questions and gives you the gist of how to use it.

It has a trickle charge feature which I’ll be trying. Hopefully this will prevent my battery from dying the next time my car.

I’ll update this review if I run into issues later, but so far, so good!
