Why do I need a solar charger?
A solar charger is a device that uses solar panels to convert sunlight into electricity. The generated current can then be used to charge batteries or power electronic devices.
At the core of any solar charger are solar panels. These are a collection of photovoltaic cells. They convert the energy from the sun’s rays into direct current (DC) electricity.
Besides smaller chargers that generate between 10 and 50 watts we have also reviewed two large ones GRECELL 200W Portable Solar Panel and Renogy 200 Watt 12 Volt Portable Solar Panel.
Here is how they help you:
- Solar chargers can charge electronic devices like smartphones, tablets, laptops, and cameras.
- Solar panels can power outdoor equipment such as lights, fans, and refrigerator, making outdoor life more comfortable.
- Solar panels can provide backup power during power outages, especially useful during natural disasters.
When a hurricane hits it can take weeks to restore power. If you have a solar charger there is no need to worry about charging phones and devices. Larger ones can easily power your appliances.
Power outages can also be caused by reasons beyond natural disasters. If vandals targeted your area’s power supply and caused an extended outage, would you be ready?

What we liked:
GRECELL 200W Portable Solar Panel is a serious player. At 16.5 lbs it is too large to be carried by hikers and meant for camping. The large wattage means you can power everything in an RV except a microwave. Even that is possible with four of these working in parallel.

Pros:
- High-efficiency solar panels that can generate up to 200W of power
- Parallel port that can increase the power output by connecting multiple foldable solar panels
- Built with a carry handle to load and unload effortlessly
Cons:

Verdict:
If you want lots of power, this is your answer. But you might have to fiddle with the charge controller to tune it perfectly. Definitely not for beginners who have never used professional equipment before.
