Best Solar Chargers in 2021 – Reviews From An Outdoor Sportsman

If you’re constantly on the go and you like to hike, camp or climb, then you know how important it can be to keep your battery charged on certain devices. However, if you don’t have access to power, you can’t charge your devices and a standard portable battery charger won’t work because once that is drained, you can’t charge it.

This is where the solar chargers come into play. Solar chargers rely on the sun to charge up the battery that in turn will charge your phone. If you are constantly on a go, these chargers are a great way to ensure that you don’t get stuck with a dead battery.

Things To Consider – Best Solar Chargers in 2021


The wattage you should look for is dependent on what you plan on charging with the charger. For example, a four or 5 watt panel is going to be great for a lot of the smaller handheld devices like an mp3 player or a smaller cell phone. Unfortunately, most smartphones, especially iPhones, are much more power hungry and will require you to get a seven watt panel in order to charge it properly.

Additionally, you can continue to go up if you want to charge bigger devices or multiple devices at onces. If you want to charge an iPad, then you’re going to need to go all the way up to 15 watts, which is where things start to get expensive and pretty bulky.

Output Power

The output power of the charger is going to be incredibly important because it can make the difference between whether or not something is going to charge. You need to make sure that you match your needs to the amps. For example, a 2.1 amp will charge your iPad a lot better than a 1.3 amp port would. Be careful when you look at the reported amperage that the manufacturer reports.

Some of them list the maximum for each individual port but there are some places that combine the two and list the sum, so be sure you know which number is listed.


Pretty much every single solar panel charger that you are going to look at is going to include USB ports, and many of them are going to include multiple to choose from. Additionally, some of them even have one port that has a higher amperage than the others to help meet the power demands of some of the newer iPhones and tablets.

Despite how universal the USB port is, it’s important to note that it isn’t going to be able to charge everything you want. For example, if something plugs into a wall outlet or a cigarette charging port, you’re going to need to have a different device to charge it.

Integrated Batteries

Some of the chargers that you are going to find have a battery included so that you can leave the charger out in the sun all day to charge up the battery and then take it back to your camp at night to plug in your devices. These types of charger are become very popular for their efficiency and effectiveness.

Unfortunately, there are quite a few drawbacks to these devices because they do a lot of things okay, but they don’t do anything really perfect. The solar panels can be too small to charge the battery at a quick rate and it leads to a poor lasting battery.

Ease Of Use

Since you might want a solar charger because you’re going out into the woods or camping or something but you don’t want to stay disconnected, it’s pretty ironic if you have to mess around with the charger because it isn’t working. If you’re buying a solar charger, make sure it has an auto-restart feature.

Some of the panels automatically stop charging if a cloud passes or someone casts a shadow over the charger. Without the auto-restart, it will not charge again until you unplug it and plug it back in, which is a huge dealbreaker. Additionally, make sure the setup suits your needs and there are not excessive adapters or cords needed.


If you are trying to buy this portable charger for traveling or to keep in your backpack, then you want to find one that is going to weigh very little so that it doesn’t weigh down your backpack. Be careful when you go to look at the weight of the product because not all of them list the weight of the unit as a whole.

Some of them are only going to list the weight of the panels themselves. Remember as well, if you choose to go with one of the most lightweight ones on the market, there’s a chance that it won’t be as durable if you drop it.


Similar to the weight of the product, the size is going to be incredibly important if you are planning on bringing it with you wherever you go. Most of these portable chargers can be pretty big, which is not ideal if you plan on bringing it with you. However, if you go with some of the smaller ones on the market, it will not hold as much battery in it and you will need to recharge it more often.

There are positives and negatives to both sizes, so if you value size over performance, then go with a smaller one.


The versatility of the portable charger is going to be one of the most important things for you to consider because you want to make sure that it is able to do everything that you need it to do. For example, make sure that it has one or two USB outlets depending on what you need and make sure the amperage is what you’re looking for as well.

There are other ways to charge things that require a standard wall outlet, but the safest and most efficient way to charge with a solar charger is through a USB outlet.
