Solar Battery Chargers

How many batteries can I charge at a time with the TravelSol Flex Charger?

The TravelSol Flex Charger can charge 2 AA, 2 AAA, 2 C, and 2 D batteries at a time.  You can not charge two different batteries at the same time, such as an A and a C.


Are Solar Trickle Chargers Any Good?

If used correctly, for the right goal, solar trickle chargers work great.  Solar trickle chargers are not designed to fully recharged drained or nearly drained batteries.  A solar trickle charger is designed to maintain the current level of a deep-cycle battery.  In other words, you can have a vehicle sitting for an extended period of time without having the battery go dead from disuse because the solar trickle charger keeps the battery level maintained.


What does the charge controller do?

A charge controller ensure the batteries don’t get overcharged in bright sunlight as well as to monitor the amount of light in the surrounding area and turn the LED (light emitting diode) light on and off.


What is the difference between a PWM and MPPT charge controller?

Pulse-Width Modulating (PWM) charge controllers use complex algorithms to determine the amount of charge going to a battery and slowly taper off charging as the battery becomes full. One of the greatest advantages of PWM controllers is that they have been around for many years, are cheaper, and are available in a wider variety of sizes for different applications. Some drawbacks of using a PWM controller are that when sizing a system the controller must match the voltage of...
