    Golden Review Award: 6 From Our UsersI rated this product a 5 because it worked , speed of delivery (@36 hours after I ordered) and low cost. But as some previous posters commented, the instructions could contain more info. For example, when the “current” gradually drops from 6.2 to about 2.0 over several hours , what does that mean ? Is this a good sign ? The product worked for me although it took over 7 hours to charge my battery and I think it was still recharging the battery when I unplugged to to check if my car would start. Seems like a very low cost solution to just add more examples or scenarios in the manual.

    Golden Review Award: 4 From Our UsersI’ve had an issue with a car battery and wanted to charge it up for safety. Initially it wouldn’t work and when I actually took the time to read the display I realized I reversed the + and -. Stupid, I know. Anyway the fact this little device caught it is pretty nice.

    After that it charged the battery just fine. No issues to date, if that changes I’ll update this review.

    I was pleasently surprised the first time I used this charger, it instantly identifed the type of battery and the charge that was left. It took my tractor battery from 20% to a full charge in about 2 hours. My dewalt charger can’t do that.

    Golden Review Award: 3 From Our UsersAfter my last cheap car battery died early I decided to buy this. It seems to work great and fits under the hood right beside the battery. I just clamped it on and fed the plug out through the grill and figure things will be okay even if someone backs the van down the driveway without first unplugging this gadget. 😉

    I have popped the hood and seen that it says ‘OFF’ even though its plugged in. That must be what it does after it determines the battery is good. It comes back on and runs a while if I unplug and plug it back in a little bit later for testing purposes. I used to take out the car batteries and bring them inside if the temps dropped below -15. I don’t plan to do that on the van that has this thing attached.

    Golden Review Award: 2 From Our UsersI picked this up yesterday to charge a battery that my old charger wouldn’t do anything to. (It’s 20+ years old, it’s tired) Just hooked it up this morning and the display is just flashing on and off. No clue what’s happening, can’t find any info on it in the manual or on the web, and I’m a tad disappointed it isn’t connect and it all works as it was advertised.

    Remember that old saying, “If it’s too good to be true it probably is”, and you won’t be disappointed as much. Gonna go check it and hope it’s doing something besides blinking, but I ain’t holding my breath.

    Very very unhappy customer. 🙁

    UPDATE: The company contacted me before this review went up and offered to send me a new unit as they thought mine was defective. They were right. The new one came yesterday and worked exactly as described and my car is now up and running. Very pleased with the results and really impressed by the customer service. Would recommend.

    Golden Review Award: 6 From Our UsersI left my car for a few weeks and the battery ran dead. After having to jump it a 2nd and 3rd time after running it more than 30 minutes I hooked this thing up overnight on repair mode, then let it run a charging cycle for a few hours the next morning. I had lots of time and didn’t expect it to be done in a couple minutes. Since then my battery has been working fine.

    Seems to need battery cables connected before a/c power, and when done disconnect battery cables then a/c power. Unit does show voltage levels of battery connection.

    The battery charger was really straightforward to use and the LCD display was easy to flick through the options with one button. I’ve used the repair mode on a battery that I thought had had it, but it seems good to go now.

    This battery charger is made from good quality materials and is super simple to use. You connect it to the battery then select the mode with a push button and it will analyse and then charge the battery using the appropriate current and so on. Once full it will then switch to a maintenance charge to keep the battery topped up and prevent it from being damaged due to over discharge. A clear display indicates the status of the process.

    I have used it on my car, a small gel leisure battery and my motorbike and it works well. Charging is fast and the maintenance mode seems to be working fine.

    I have a couple of issues though. Firstly it says 24 volts in the description but not on the unit itself so I would be wary expecting this to charge a 24 volt battery. Secondly I do not like the fact that it has a fan. For short term charging like overnight or a day or two then I am okay with the fan running, but for a maintenance charge I do not like the idea of a fan running for weeks or months a there is a chance it could fail and then who knows what would happen… And finally as it is a smart charger it will not charge a fully flat battery as it needs to detect a certain amount of voltage to start up. This is common with most smart chargers but some of the (very much) more expensive ones have an over ride to start charging a dead battery.

    For the price this is a good value charger to have around the house. It is easy enough to use and should cover most domestic charging requirements.

    This is easy to use for everybody and not just tool savvy people. The instructions are good, after connecting you choose the type of battery and that’s pretty much it, it’s automatic so that’s all you do to maintain a battery. I have a camper van so the battery gets some hammering with devices.

    The build quality is ok, I’d say middle of the road plastic quality, not cheap but not the quality of a premium product. For the price though it’s a good product and seems solid and the readout is easy to see and the trickle charge is invaluable if hooked up so you’re not yo-yoing the battery.

    I could recommend this, does the job well.

    Very easy to use, mid range quality

    This is a nice and reasonably priced car charger. It is there to maintain the health of a car battery or to recharge it after a prolonged period of car battery disuse to maintain its health.

    Note it is not a jump start and it requires being plugged into the mains so you can’t just keep it in the car and use it when you have a flat battery. It needs to be plugged in so you need to be near a house or garage.

    It is relatively well made, comes equipped with the charging cables and is great value at its price point. It does exact;y what it says on the tin.

    Great budget battery charger. This charger was 25, it provides a good reasonably quick charge, has a display giving you useful information and is fairly compact.

    The only obvious downside is the length of the wires. Would have been 5 stars with a longer length to the clips.

    This is a compact smart battery charger that has a decent output for a relatively low cost.
    It comes with instructions in a decent enough box to store it in your car or garage.
    It is very similar to a noco genius charger I used o have permanently wired up to a motorcycle to keep the battery good to go on the rare occasions I got to go and frighten myself on it!
    That charger did pretty much the same as this one but cost a lot more money, the only real difference was a easy to disconnect plug on the bike so I didn’t have to expose the battery to take it off.
    This will recharge and recondition most car and motorcycle batteries with ease in a relatively short while.
    The battery may well make some odd noises while it is being reconditioned but I think that is normal!
    It feels well made in the hand and actually has a cooling fan built in so it can be used overnight if needed although the instructions do say you should not use it unsupervised and I dont know about you but I am far too old to stay up all night supervising a battery charger these days!
    The display is clear and easy to read and for <20 (at time of review) I really cant see how or why anyone would complain! Happy to help!

    6-Amp Car Battery Charger,

    This is a great compact charger at a reasonable price. It charges pretty fast and will automatically assess the battery’s capacity and charge accordingly. It also has an auto on/off function. It’s simple to use and handy to have in emergencies. The only downside is the leads. they are quite short and the crocodile clips aren’t the sturdiest, but for the price, it’s acceptable, and it does work.
    The charger is lightweight and will store in a small space in the boot of a car.
    Overall, it’s one of those things you don’t need until you wake up with a flat battery and wish for all the world you had a charger. It will save you some hassle in the end.

    This is a decent entry level car battery charger/maintainer. I already have a far more expensive Noco Genius which is obviously far better quality but that takes nothing away from this budget charger. Very easy to use with a clear display and it will charge a dead battery quite quickly. It will also maintain a good level of charge in an older battery so you can leave it on maintenance charging for extended periods to avoid getting a dead battery after a few weeks or months.
    Cheaper than some alternatives but it may save you money and trouble in the long run.

    Multifunctional 12V car battery charger.

    For a small size and a cheap price, this isn’t a bad little charger. You can use it for cars, trucks, AGM, motorcycles and more. It seems well made, durable and sturdy. It’s only a mere 14.5cm x 8cm x 6cm, with an 80cm long power cable with a UK plug on and 60cm long cables with clamps on the ends. Honestly the only issue I’ve had it, the cables could really do with being just a bit longer.

    The screen will not come on until the clamps are connected. The charger will auto detect which battery it’s connected to and the capacity it can go up to, as well as the charger automatically detecting the weather environment at the same time, to make sure the status is adjusted correctly to keep it all safe. You can see the temperature, voltage, current, repair mode, reverse connection/abnormal, summer/winter.

    I would recommend this car charger. It’s quite useful to keep in the car, it takes up no space at all so you could keep it on a bike too. Not bad for the price.

    The battery charger arrived in a box with an instruction leaflet. The charger is fitted with a sealed 3pin plug. The charger itself is very light weight and plasticky, the leads to the crocodile clips not very long and again feel cheap although they do have strong springs. The display is clear and easy to read, it will detect the current level of charge on your battery and switch off when fully charged. I have been having low battery warnings on my car recently and this topped it up well, I just hope it lasts.
    A good little item for having in the boot for an emergency as it is so small and light compared with my old heavy charger. I think 25 is reasonable price given the quality of the materials.

    Small and light weigh

    Gone are the days when battery chargers and jump leads, or woe betide seeking the help of family and friends to push a car to get it started due to a flat battery. Modern cars tend to manage the electricity generation far better and of course, modern car batteries themselves are far superior to their predecessors.

    So why do I want a battery charger? As a member of an MG owners club, where even the “modern” MGF and MGTF have a never tendency to discharge their battery when stored, this type of charger is a bit of a Godsend! Left on a trickle (maintenance) charge when the car is not being used does prevent that heart sink moment of jumping into your vintage car, starting it only to hear that family sound of an engine slowly turning over.

    So a four star rating? Yes. This charger will charge your battery quickly from flat, or as I will mainly use it, to keep a maintenance charge when my car is not being used. I actually like the charger, but am not so keen on the requirement for a cooling fan, which for me suggests that it may boost a battery faster than what is good for the life of a battery: hence the need to cool the charger. 6 amps will charge the battery very fast, but having never needed it in over 50 years of motoring, I can’t see the need now. The display panel is a useful element and indicates the level of charge.

    Quality of construction is commensurate with an item costing 24.99 as at 14th June 2022. It isn’t bad, but you get what you pay for.

    Overall, I found the item good value with the big question being, would I buy it and my answer is “yes, ideal for maintenance charging of a car in storage”.

Since I started working from home; when I do venture out it is not far or for any real length of time and my battery on my Jeep gets weak (for whatever reason when I do get out it seems it is raining and the demand for headlights and wipers is needed) I have used this twice to charge my battery since I am using more battery than my alternator generates on these short trips and it works like a champ. It will not over charge your battery as long as you select correct type of charge. Mine came in the original box with instructions for setting it for what type battery charging. I love how small yet powerful it is and highly recommend everyone have one in their vehicle. This is NOT a booster so don’t expect to connect it and immediately go; then again if you need a jump you should have a set of jumper cables. It can function as a trickle charger/battery maintainer so the directions say, but I have not tested that function. Happy with my purchase. Works for what I needed. Certainly a LOT cheaper than a larger stand alone unit, but also a LOT harder to steal!
