NOCO GENIUS1: 1A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – For Lead-Acid & Lithium Batteries

This arrived in 24hrs - seller is to notch 5 star business. This is my 4th Genius - they are superb. Cannot fault quality and ease of use. 10/10

Works perfect for charging my motorbike and keeping the battery healthy when not in use. Compact size for wall mounting too.

Had to send the first charger back as it was defective, displaying red and green flashing LEDs alternately, before shutting down after a few minutes. The item had arrived unsealed and with tears to the packaging so it seems as it had been returned as defective before being sent out to me. The replacement arrived the next day, properly sealed, and I set it up in my camper. It worked exactly as it should and is now keeping the starting battery topped up.

Not as big as I thought its a large plug. Easy to put together and use make sure u pick right setting for the battery u have. No instructions of how to connect it together or what light means. But very easy to connect it and questions get answered on site questions area

Bike battery went and this was a life saver!

Really good and easy to use

Partner’s battery in her car went flat.. wasn’t quite dead due to the cold weather so we took a punt at charging it ourselves. She obviously let me get the battery out of the car and into the house (hard part) and the charger did the rest. Even though it doesn’t produce much amps it did charge the battery until it was 75% charges overnight. Quicker than I expected. The device is very versatile, if you had the outdoor/extentension cable you could have charged it that way. The cable length is adequate and the actual design is really compact and slick. No trouble following the manuel and getting it charging the battery in no time. Great product, great price and definitely will be suggesting it to my friends and family if ever needed.

I have had 3 of these now (2 replacements for faulty ones). Maybe I'm unlucky, but I've had 3 these that start off OK, but after a short while (a couple of weeks) fail to charge. The red LED pulses, but never goes green. I tried on 4 different batteries, all of which show as fully charged and good on other chargers, and have been tested and proven good batteries (1 was brand new!). The charger doesn't even seem to be trickle charging. This charger was used on my motorbike over winter, so keeping the battery topped-up is important, but they seem to fail after a short while. I have gone back to my old Motopower charger, which seems to have no problems.
