This Low Dropout Voltage (LDO) solar charge controller uses a simple differential amplifier and series P channel MOSFET linear regulator –their compatibility seems like a marriage made in heaven.

Using a PWM charge controller, you cannot use this power output to charge a 12V battery. However, an MPPT charge controller can lower the voltage to 12V while increasing the current to 40 amps ...

For fans of golfing or boondocking (off-grid RV living), an MPPT controller allows you to charge a 36-volt or 48-volt battery with a single flexible 12-volt solar panel attached to the roof of ...

Along with the Nomad 20 we used the Guardian 12-volt charge controller, which allows connection of a solar panel to a 12-volt lead-acid battery to monitor the charging of the battery.

Versatile: Compatible with 12V/24V/36V/48V systems; Smart Control: Remote app and LCD display; ... At $119.99 with coupon, this solar charge controller offers excellent value for advanced features.

It looks great, but [Brandon] has a long list of improvements to add, including a solar charge controller, volt and amp meters, and an LED power switch. Ammo cans make solid project boxes.

If your car's battery needs a boost with a 12V charger, you may be wondering how long the whole ordeal will take. A bit of a wait is better than alternatives.
