    So simple even I can use it !

    It really does tick all the boxes .... automatically sensing voltage, battery condition and incorrect polarity so protects itself and the battery from my own clumsiness and stupidity. Best of all it can be left connected 24/7/365 without risk of stressing the battery and, should there be a power-outage, resets and carries on when the power returns needing no user intervention. I have a second home and vehicle in a region prone to power cuts, so I'm hopeful that this unit should guarantee that I'll never again have to perform CPR on a comatose car after a long flight. At 1/3 of the cost of the unit it replaces it's superior in every respect.

  • Most critical review

    The unit worked well but be aware of the shortcomings of the mains lead.

    The charger worked well and charged my battery efficiently with indicator lights showing rate of charge and battery capacity. The unit can be used with a wide range of mains voltages but the only downside was that it was fitted with a 2-pin mains shaver type plug which meant I had to change it for a 3-pin 13A plug fitted with a 3 amp fuse. The mains lead is also extremely short and needed an extension lead. The unit was marked with a CE label so presumably it was safe to use.

  • Safe battery tender/charger

    I bought it because my old diesel car didn't start after staying for three weeks in unheated garage (temperatures around freezing). First I charged battery with traditional big current charger but wanted to have something that I can leave safely for extended periods - as I'm cyclist by nature and don't use my car very often. Behavior of this charger seems to be very correct and safe. First, it checks battery voltage and starts initial charging. Voltage goes up until battery is 100% charged (4 bars on display). Then charging apparently stops as voltage drops to healthy 12,8 volt or so. When I connected charger after long drive I could observe all process going fast as battery was already well charged. This behavior lets me to believe that I can leave this thing on without the danger of overcharging - unlike the simple charger. P.S. As three weeks for my battery to self discharge seemed to me a bit too short (battery is only three years old) I also checked my car. I found that ground wire from battery had a bad connection (it generated heat) and car didn't charge battery as it should (only 13 v or less). That was the reason for all trouble. Anyway I'm going to use this charger in the winter months as it doesn't hurt to have battery always fully charged while you cycle.

  • Look at this before CTek!

    I currently have several Ctek chargers and recently discovered these which are a fraction of the price. This charger functions perfectly and is by no means inferior in quality or operation. Some cheaper chargers are fiddlely to find the correct mode of charge, these are very easy to operate, even an old duffer with bad eyesight like me can use these! Definitely worth a look at less than half the price of others.

  • Little but very large with useful features.

    This charger has proven its worth by reviving two very depleted car batteries back to 100% charge very quickly. This is in danger of becoming one of my most useful tools and a very strong favourite. It is light, very simple to use, small and powerful. The tiny cooling fan startled me as most chargers are silent. A charger of great benefit and value. Long may it live!

  • Very reasonably priced, easy to use vehicle battery charger

    Good quality and very easy to use. A relatively large screen to show the voltage and how much the battery is charged/charging. Easily switch between different charging options from (Fast to slow trickle charging). Very good product!

  • Excellent charger

    I was a bit dubious about this charger and whether it would be any good but for the price I thought it was worth a punt. It turns out it's excellent once you understand how it works. The only setting you need to change is the battery selection option the rest is automatic, this can be a bit confusing to start with as the instructions are fairly pathetic. It's much the same as the maypole 4a charger so you can follow these instructions maypole.ltd.uk/mp7423-battery-charger-38a-12v-auto-electronic Anyway just buy it, it works perfectly and has revived my battery quickly and easily when my old dumb charger couldn't

  • Good quality robust unit that even tells you if connected the wrong way round!

    Great quality and easy to use, I used it to replace my battery conditioner on my 2000 Aston Martin DB7 Vantage and it works as good as the original but for a fraction of the costs of an original. I also like the digital readout showing the voltage of the currant battery condition.

  • Good value

    Needed a charger to charge my caravan battery as it's been in the house over the winter. Read the brief instructions plugged it in and away it went. Charged battery within a couple of days. Previously used a CTEK but didn't to pay that amount for very occasional use. Great value for money easy to use, digital display super bit of kit. Every bit as good as the above mentioned CTEK but much cheaper option Certainly recommend

  • Brilliant and simple to use. But make sure you order the type with the correct mains plug

    Brilliant and simple to use. Just connect this charger to your battery and its smart software takes over. BUT - make sure you order the one with the correct mains plug for your country. I ordered the wrong one so had to change the plug to the UK 3 pin type. I should have been a bit more careful before ordering. But this is a good charger. No switches - just leave it connected to do its job. It keeps you updated on charging progress. Approx 3-4 hours to fully charge.
