No switch or light to let you know it's on? Just plug into cigarette lighter in car, pleased to tell you it works as it's keeping my battery topped up.

Working well
Great purchase at a reduced price. Used for a car that is not used for long journeys and likes to drain the battery. Since getting this we have had no problems with the car. Plugged into the internal power point.

Great item from Argos
Easy to work, and first impressions are good. I will know how effective it is with a bit more regular use. Pleased I purchased this to keep my battery in good health.

Works and could be improved with optional OBD plug
Car was stood for months; battery dead flat. Got this and tried the cigar lighter socket. Mine only works on ACC key position, so, no use for overnight charging. I could have just gone under the bonnet, but bought an (on board diag's) OBD to lighter socket adaptor from a 3rd party, instead. The OBD plugs straight in, is forever live and connected to the battery. Left it for a couple of days - now at 8V from flat, and still going up. Wish I'd got the Ring Solar Maintainer before winter! Would be good if Ring had the OBD plug, as well as the crocs and lighter plug as an option. Still well worth it, especially if you hate getting under the bonnet, or getting rained on. Just pop inside the car under the dash, plug the OBD in, and let it do its thing; nice float charge and safe for the battery, too.

Hello sasgps,

Providing it's between the power requirements for the panel to work then you will be able too.

Hello Will,
From the information we have available, I can advise the Ring RSP500 5W Solar Powered Battery Maintainer is designed for 12V batteries and is ideal for maintaining the charge in vehicles that are not used frequently, such as caravans, classic cars, motorcycles, and golf trolleys. However, it is not compatible with start-stop batteries, which often require more sophisticated charging systems due to their higher demands and frequent cycling.
Thank you for using Q&A

Hello JT,
From the information we have available, I can advise the Ring RSP500 5W Solar Powered Battery Maintainer comes with a 3-meter power cable. This should be sufficient to reach from the boot of your Volvo V70 to the solar panel, allowing you to maintain your battery even if the dash socket turns off.

Hello Erin,
The Ring RSP500 5W Solar Powered Battery Maintainer can be used outside the car as it has a water resistent casing, but it's recommended not to allow moisture or liquids to collect on the aparatus.
