We found that the best car battery charger is the NOCO Genius G750UK Battery Charger. It has a strong and sturdy build, is simple to use and charges fast. We also found 9 more units that performed exceptionally well. The Ring RCB208 12V 8A Battery Charger offered the fastest charging time on our list thanks to its 8 Amps capacity.

NOCO Genius G750UK Battery Charger Review – 100%
We liked the versatility that comes with the NOCO genius. Not only were we able to charge the car battery, we could also charge the motorcycle and lawn mower batteries as well. The amperage was good and was able to charge quickly and efficiently even faster than the ARTECK Auto Battery Charger
The main drawback that we noticed is when charging a completely flat battery, this charger tends to struggle adding the initial amount of charge. However as soon as the fist small charge gets in then it works well. We found this inconvenient.

The first thing that we noticed with this battery charger is the strong and sturdy build. This means it is durable and can last a long time. We also liked the easy to carry handle. The 6 Amps allows it to charge a car battery quite quickly.
However, while charging one of our car batteries we noticed that the charger got quite warm which is not something that we liked as it is indicative of its inability to sustain long periods of charging.
Another thing is that the meter shows voltage and not amps. We thought that it could have been easier if it read amps.

We immediately liked the strong and sturdy frame of the Draper. It looks durable and able to last a longtime. It features a strong and comfortable handle for easy carry. We also liked that it could conveniently charge batteries up to 45 Ah.
This car battery charger features a long cable with a length of 1.5 meters. With a 4.2 Amp capacity, it can charge a battery within a reasonable time frame.

We also found that it offers security measures against overcharging as well as reverse polarity. It also managed to charge a flat battery in a few hours.
The main drawback that we noticed was with the clips. They are a bit too small and may not open far enough to easily clamp onto the battery’s terminals.

We immediately noticed the small and compact build of the Streetwize battery charger. The design made it quite simple to move. We liked the fact that it comes with heat and polarity protection and also found that it could charge the car battery quite quickly.
The drawback that we noticed is that like the Marko the charger tends to get warm quite fast. The lights are also not very reliable as the full light showed dim when charging. The crocodile clips also don’t seem to be very strong.
Ring RCB208 12V 8A Battery Charger Review – 82%
The Ring RCB208 was a fast charging car battery. It was able to charge a fully flat car battery within a few hours. This is mainly due to the 8 Amps capacity. We liked that it operated silently and unlike the Streetwize SWCBC6 Compact Battery Charger, it doesn’t heat up quickly.
However, we didn’t like how long it took us to get the charger working. It is certainly not the easiest to use and does take a bit of fiddling with. Connecting the earth took a bit of time. We also found that the rapid mode cut off quite quickly.

We noticed the heavy-duty case of the fifth gear which made it durable. We also enjoyed how simple it was to carry thanks to its convenient handle. It looks good and we found that combined with being light weight, it charges the battery quite fast.
However, we didn’t like the build of the indicator. It looked low quality and did in fact give up as we were testing out the car battery charger. This was also not the quietest charger we tested as it produced quite some noise while running.
