I chose this charger as a backup charger for my 750 Watt Electric Bike. I charge my bike battery every night, and I am used to the charger that came with my bike, so I will be able to compare the two.For starters, this Smart Charger came with 5 different plugs. My original charger came with only one. With that being stated, I will never use the other four, so I will probably give those to a friend. Still, if you have an electric bike, and a scooter, and a golf cart, this would be a great charger for you.Both chargers set up exactly the same. They both have the red light meaning that the charger is charging, and both turn green when the battery is finished and it is fully charged. Those are the similarities, but there are a couple of differences that I want to share. This new Smart charger has two fans for cooling the unit down. My original charger does not have any fan at all. This new Charger does run hotter than my original, so maybe there is a reason it has to have two fans. I don’t know the answer as to the reason. I am simply sharing the differences. This new Smart Charger charged my bike battery from 36% to 100% in just over an hour. That is quite a bit faster than my original charger by about 30-40 minutes. That is a significant improvement, no doubt.The other difference has me a bit concerned, and seriously , I do not know as to what is causing this anomaly with the new Smart Charger. While the charger is charging my bike battery, I can turn the bike on to get the status of how much charge the battery has taken. I can do this with my old charger, and I do, safely, with no concern or worry, for the bike simply is turned on. It stays parked, motionless. When I turn on my bike with the new charger charging my battery, my bike will jump forward and sort of take off without any driver. It is dangerous, and it can be detrimental to my well being and the bike itself. I simply am never going to turn my bike on when charging with the new charger. Still, I had to warn prospective buyers about this anomaly. It might be something quite common. I have never heard about such a thing, and I don’t know who or how to ask he question about it.As for the new Smart charger, it works really well, and it works super fast in comparison to the original charger. It does have a safety issue that I am hoping will be resolved at some point. Until then, I am really happy with this new Smart charger, and I am marking it down to 3 stars because of this safety issue.

I got this to charge my Apollo Pro (2020) electric scooter. The fact that its output is 4A, it definitely speeds up charging time without making either itself or the battery get very warm. The display is clear and very accurate.

I wanted a backup charger for carrying on my e-bike. My current chargers are quite large and have flexible voltage. This one is fixed at 58.8v and will support Constant Current at 4 amps until 58.8v, and then switch to Constant Voltage at 58.8v. As the description states, it flashes red and green when charging and goes solid green when done. The label says red = charging, green = no charging, which is a little misleading. The display only shows voltage, not current.58.8v CC-CV charging is for standard 14 series, 3.7v nominal, 4.2v max lithium ion batteries commonly called "52v" battery.This one is small and light, yet 4 amp (200 watt) capable, and has a cooling fan (so it is not waterproof). I converted mine to an XT60 connector since I don't have an XTR connector on my battery. The wires inside the sheathing are 18 AWG in size and properly colored red (+) and black (-). The label says 100-240v, 2a max input, with 50 / 60 hz indicating a flexible global-ready power supply with a mini ungrounded iec connector (IEC 60320 C-7) so you can put any ungrounded C-7 plug you want on it.It is CE labeled, but not UL listed. Since my e-bike is simple weldable chromoly (not carbon fiber or aluminum or heat treated steel) and the battery has a voltage and current cut off already, the lack of UL listing isn't a major problem for me.
