Solar Battery Chargers Buyer’s Guide
Now that we have gone over a few solar-powered chargers and maintainers, it’s time to identify what you need to be looking at while buying these products.
Multiple factors must be considered so that the charger and maintainer meet your expectations and efficiently extend the battery’s life.
To help identify these key factors, here are some pointers that you can quickly go over while searching for the ideal device.
-
Charging Power
The ideal solar charger and maintainer will do its job even if it is a cloudy day. Plus, it is essential to make sure the device can be plugged into a cigarette lighter and also attached to the battery directly to charge it.
-
Reverse Charge Protection
While searching for an efficient charger and maintainer, make sure it has an in-built diode. What this does is, it will prevent the charger from taking power from the battery once it’s done. The diode will protect the battery from discharging as well as overcharging.
-
Size
Based on the automobile or equipment that needs the charger, it is crucial to select something that will fit comfortably and without hindering your vision.
These chargers and maintainers come in various sizes, so it is vital to keep in mind that it needs to be portable and easy to carry.
-
Mounting
Suction cups are included with all chargers and maintainers to allow attaching them to the windshield. However, specific devices also come with back straps through which it can be attached to the sun visor.
If you intend to carry it around, then having both suction cups and straps will significantly help.
-
Overall Design and Make
Since these solar chargers and maintainers are aimed at outdoor use, it is essential for them to be waterproof and windproof. Ensure that the device can withstand all the different kinds of weather conditions and heavy wind and impact (especially if it is for marine automobiles).
Verdict
Solar battery chargers and maintainers are of great help if you have vehicles that are not being used and are in the garage for a greater part of the year. We hope that this review and the buyer’s guide clears out any confusion or doubt about solar-powered chargers and maintainers.
Before leaving, we would like to reiterate that we recommend the TP solar unit in spite of its LED indicator issues. But, if the LED light taking power (although very low) is a concern, then the Kingsolar Solar Trickle Charger and Maintainer is a great product to consider.
Let us know if we missed out on any chargers that are worth checking out and reviewing. Until then, stay safe and be healthy.
