Hmm. This has a lot of nice features for the price. But it’s an unknown brand.
It does have a standard connector used by some other brands. There are some proprietary connectors that are better and different, but there are adapters you can order (of course an adapter costs about 1/2 as much as this entire charger unit.) If it delivers on all the features it advertises, it is a good price for the product. I don’t know about the value of measuring the temperature of the charger – that seems like a gimmick though some other brands did that too. Of course you really want to measure the temperature of the battery, but that would require an external sensor with more wires, so I haven’t seen that done in this type of unit. (some very high-end units for boats and RVs do that.)
I have been buying a lot of NOCO products because they have been on frequent sales on this and other sites, and I guess I would tend to stick with the known brand that I have good experience with. But based on the specs this is a very good price for a “smart” 4A charger even though a no-name brand.
