No, this is meant to charge a battery with AC (wall) power.

eco worthy is always best to buy on eBay, whenever I have looked their amazon prices seem to be inflated and all of their sales are run on ebay. That being said this is a solid price, it is on sale for this price somewhat often, but worth it if you have a good use for it.

Good deal. Bought it last time at $46. Have charged lfp and flooded lead. Have only gave it a short go but thumbs up so far. I did confirm current output for each setting and voltage output. It's accurate enough for my use, probably 1% error or less.

Can anyone confirm if this charger has the feature of a constant 14v DC supply? Their 5amp and 10Amp models do have it, but unknown for this model. I have the Vevor 35Amp model, which really kicks ass, but does not have the constant DC supply feature. Infact, the cheaper 10Amp SUHU model had it and Amzn do not sell them no more.

Just a cheap, true rms clamp meter with good resolution in that range. And also a good true rms dmm for the voltage.

Damn me! I should have known you were referring to voltage and current that is being shown on its display:-) Thanks though.

how would this stack up to the Noco Genius10? I bought one a few weeks ago for my 100 ah battery for my kayak. I understand the obvious that it would charge 10 amps faster

Two pack was for $85 a few days ago.

Can this be used on a regular lead-acid battery in a car?

How does this compare to the hundreds of battery chargers on Amazon for cheaper with higher current output, and can do AGM batteries with repair mode?
