4A Smart Car Battery Charger, 6V 12V Automotive Charger Maintainer Fully Automatic 8-Stages Trickle Charger for Automotive Motorcycle Car Battery, Portable 4A Smart Car Battery Charger 6V 12V

These work great! I have had one charging my motorcycle battery for over a year now. No more dead batteries after sitting for a month. The display works great and lets you know exactly what charge the battery is taking. The price is a little higher than most and there are many cheaper alternatives, however, I am happy I purchased this one. Easy to use and well built. I just purchased another one to maintain my Jeep battery.

Works great as a motorcycle battery charger maintainer. Displays battery voltage while charging or you can just plug it in to check your battery voltage. Good buy for the money.

This charger is working great and very convenient with all required identifications. My battery won’t charge and i used my old charger, it didn’t charge and I thought my battery is dead. This charger is working fine and charged my battery quickly. Very nice purchase!

I have always been a "popular brand" guy when it came to battery tenders. I decided to give this one a try because it had a lot features for the price. I like the screen so I can see what it happening and if there is a problem with the battery. Much more helpful that just a blinking light.Got the battery on my motorcycle charged up overnight, and now it is just maintaining it until I go ride again.Compact design, multiple batteries it can be used, great value.

Gets the job done

I purchased three Adakiit chargers, one for each motorcycle. I looked at many different brands and read reviews. I was really contemplating CTEK, NOCO G2, and the NOCO Genius G4 - particularly the G4 since it can charge up to four motorcycles at the same time and it seemed a lot of quality for the price. However, when you factor in the need to purchase SAE connectors as an accessory (at $13 x 3), the price was far less attractive. Also, if the G4 went bad, I would have to replace the whole unit at full price.I also learned from reading the fine print that some of the other cheaper chargers were not suitable for motorcycles, and many did not have more than two or four stages of charging, while Adakiit has eight stages, and came with SAE connectors that mated with my already installed pigtails.Using them is a plug and play affair. Once plugged in, the charger performed a quick diagnostic and determined the correct voltage (LCD display) and showed they were fully charged. From this point, it should determine the best way to maintain the batteries (via pulse).I feel the devices are sturdy, and appreciate the red plastic coloring. I have high hopes for longevity. The chargers are a bit bigger than I expected, but I have a Battery Tender Jr. for packing on the bikes for trips. These can also be mounted on the wall near the bike if desired. At 2 Amps, it can cut charging time in half from other chargers that are only 1A or less. So far, I'm happy with the decision.

Hooked this little thing up to my truck to keep the battery in good shape. The truck has a lot of little electrical vampire features and so can drain a battery in a few months of being left alone. They battery cord adapter fit right onto the terminal screws near the battery and has a rubber sleeve and attached cap to keep it protected from elements.I didn't want to have the charger outside of the garage so I purchased a 25 foot extension for the battery hookup wire. It plugs right into the battery adapter and the charger wire - now I have about a 31 foot cord to reach the truck. The charger stays inside the garage and the cord runs up under the truck hood.(25 Foot Quick Disconnect Harness,DC 12V Power Extension Cable ,18 AWG Gauge + Dust Cap )Before driving, I unhook the extension (leaving the battery hookup adapter in place), use the rubber caps to protect both ends of the wires (the extension and the battery hookup) and the battery is at 100% when I start the truck up.I have been using the charger strictly for a trickle charger so far except when I first hooked it up the truck battery needed some charging. The charger went straight from charging to trickle with no intervention. I can clearing see the device saying the battery is "FUL" when I enter the garage so a nice indication that all is well.I have used the device now for about 2 months so I cannot yet say anything about how durable it is. I will revisit this review in 6 months or so for an update.

This charger is exactly what I needed to keep the battery charged on 2 of my vehicles. I have a 20 year old sports car that only has 19,000 miles. as you can guess without a battery maintainer I would be sunk. I liked the ease of use the different methods of hooking it up, I bought a second one for my 20 year old truck that I don't drive enough to keep that battery charged. I would definitely recommend the use of this charger, maintainer.
