A mighty little package
Highly reliable and still working perfectly after regular use and even charged a flat car battery overnight without overheating. Good build quality.

Good value.
Good value for the price, trickle charges my classic car nicely, and cuts out when the battery is fully charged. Be aware it is a 0.6amp charging rate, so takes a while if the battery is low. Cables are a good length and the clips fit securely on the posts. I would have liked a read out of charge level, but for the price you can't have everything!

Perfect for charging 12v Kids Ride On cars/quads/bikes
Having lost the charger for my grandsons 12v electric car, I did a lot of searching for a replacement charger but was surprised at how expensive they were. So I decided to order this charger, now you can use it straight out of the box by switching the switch on the front o 12v and then removing the seat cover on your kids ride on, which is where the battery is normally stored and clipping the connectors from the charger to the positive and negative terminals of the battery. The charger has a useful indicator which is green when charging and turns off when the battery is charged. I replaced the clip on connectors on the charger with a 5.5mm x 2.1mm male connector (which are very cheap) so I could plug directly into the charging socket of the ride-on car. Obviously only do this is you are happy changing the connector but it makes life a lot easier. The 600ma charge rate, takes a few hours to charge the car but does a good job. Overall I can thoroughly recommend this charger and was so impressed I bought a second for a kids 12v ride on trike.
