My experience of current chargers is the noco 10 amp and the Ctek 4.3 amp. The noco is so conservative in its charge strategy that you’ll never get 10 amps out of it. I was quite disappointed with its real world performance. It took 24 hours to add a top-off charge to a healthy battery because it quickly moves to its lowest output mode. Being conservative, it’s the one I loan out to friends regularly.
the Ctek has a *much better* algorithm, but IMO is not as well built as the noco. It gets hot enough under full load that I put sheet metal between it and the plywood wall surface it’s mounted to; I don’t entirely trust it to not self-destruct one day and don’t want the flame-out of some small part against wood, if that tells you anything.
id go Ctek, or buy something cheaper and see how it works. If you do like the idea of the noco brand, the sweet spot is probably in the lower output units. I *do* like the quality of construction.
