What is a Solar Charger?

A solar charger is a portable solar panel or set of solar panels you can bring with you when you are hiking, cycling, camping, or doing other activities off the grid. It allows you to recharge your other portable devices such as your smartphone or tablet.

How Does a Solar Charger Work?

A solar charger harnesses the power of the sun and converts it into energy which your electronic devices can use.

Questions to Ask When Shopping for a Solar Charger

Do you get enough sunlight where you will use the charger?

A solar charger only makes sense if you live in an area with sufficient sunlight to really get the most out of the system. If you live in an area which is perpetually dark and cloudy, it will take longer for the charger to soak up power for you to use.

What type of panel do you need?

There are several types of panels: CIGS are flexible, thin, lightweight, and portable, but they are most easily damaged. Monocrystalline panels are rigid and cumbersome, but durable and more functional in cloudy conditions. Polycrystalline panels are more affordable than monocrystalline panels, but they are also less efficient.

Would you do better with power bank?

A power bank (or external battery) may actually make more sense than a solar charger if you will be without grid access for only a few days (or less). If you will be away from the grid for four days or more though, a solar panel is usually the smarter choice.

Features and Add-Ons to Look For When Shopping for a Solar Charger

Wattage/charging time

A charger with a lower wattage will save you money, but you will pay for it with longer charging times. If you only buy a panel with four to six watts, you can expect it to take three to six hours to charge up your devices. Panels with higher wattages may only take up to two hours.

Output power

When looking at the output power, make sure you figure out how it is being reported. If you have multiple ports, is the output measured for both (or all) ports combined, or is it the amperage per port? If it is the latter, you need to add them together to figure out the total amperage for the entire unit.

Connections

Several connection options may be available for solar chargers, but most will provide you with several USB ports, often including one high amperage port for particularly thirsty devices. For some devices, you may need an adapter. Many older cameras for example cannot hook up using a USB connection.

Dimensions, weight and ease-of-use

Some solar chargers are large and bulky while others are incredibly compact. Many include features which allow you to latch them onto a backpack or a bike. These ease-of-use features are very important while you are out doing your activities; nobody wants to manually lug around a heavy, awkward charger while juggling other gear.

Integrated batteries

The best solar chargers include integrated onboard batteries. These batteries are fully compatible with the charger, maximizing the efficiency of the device. The sun charges the panels, which in turn charge the battery, and then you can plug your devices in at any time to charge them up, even at night after the sun has gone down.

Accessories

Some chargers come with a range of accessories—these may include extension cables, adapters, charging indicators, carabiners, and other items. Make sure you know what accessories you need and which are included with your purchase. That way you know what you will have to purchase separately and how much it will add to the cost.
