Solar-powered battery charger for cars standing idle (or cyclists on the go)

solar-powered battery charger

The fact millions of cars across Britain are currently sitting idle is great for the environment,  but not so good for the cars themselves as batteries may begin to lose their charge. Solar-powered battery chargers are inexpensive and easy to use. Simply place one on your dashboard and plug into your 12v socket. Be aware that running your car’s engine for a short period of time won’t adequately charge its battery. In fact, it may drain it further if it is already weak.

If you’ve taken to your bicycle during these challenging times, you’ll be pleased to know that these solar panels can be clipped to a backpack and charge two USB compatible devices while you’re on the go.

Win a solar panel to trickle charge your car battery

We have three solar-powered battery chargers to give away. To be in with a chance of winning one of the solar panels simply leave us a comment and let us know what you’d charge with it.

If you have some spare time while your vehicle is sitting idle, check tyre pressures, engine oil levels, washer fluid and coolant. Check the manual or online for advice on how to do this for your particular vehicle. Also, check the tyre tread and the condition of your windscreen wipers. Replace what you can at home, such as coolant and oil, or make a list and ensure the repairs are completed when you are able to drive again. The government has announced new legislation to allow for the fact that many garages are now unable to offer MOT tests – read more.

      We have 3 cars on our drive at the moment, any of which could be needed in an emergency. A charger would ensure at least 1 car is working.

    Working from home self isolating with my pregnant wife. Her MOT was cancelled this week and so we have declared her car as SORN. Her car will now be sitting on our drive for some time. A solar charger would keep her battery topped up.

    Excellent article, very interesting and nice battery charger. I’d love one for self isolating in the garden.

    One on these would be really useful for charging my phone during long days in the saddle. Once these restrictions lift obviously!

    Great idea. For the car now while it’s not being used – saves having to go for needless drive to charge the battery. When this is all over I could use it during my cycle commute to charge my phone and the kids Nintendos

    I would take this on longer bike rides to top up my phone charge while out as I use it as a bike computer so it’s always on while I’m cycling. Plus it could be a backup for the battery on my new folding e-bike which I’m going to be using a lot after I retire next month. Otherwise it can charge stuff at home to save electricity from the grid, although we generate our own from April to September!

    My old banger doesn’t get out much (usually less than 2,000 miles a year) but now with lock-down it is getting ignored. One of these panels would be ideal to ensure it will start when it eventually next gets used.
    By the way, do ensure the socket you plug it into is “live” when the ignition is “off” (many are not).

    i’d use a solar charger to charge my phone, ipad, backup battery, speaker, headphones, bike lights, camera batteries, desklight, radio, audio recorder, toothbrush and if there’s an adapter, my electric bike. Come to think of it, how have I managed to survive this long without one?

    I like the idea of using one of these chargers to keep the car battery topped up. Even in normal times, my family doesn’t often drive far enough daily to actually charge it.

    Thank you again ETA for giving us all another chance to win something very practical and useful.
    If I was one of the lucky three, I would use it in a not very out of the ordinary way to charge my phone and action cam which I have mounted on my handlebars for extra peace-of-mind.
    I could mount the solar panel on a rear rack as I am still commuting by bike each day.
    Keep safe everyone.
