Solar Laptop Charger Buying Guide
Finding a laptop solar charger is easy, but deciding which to buy is another matter. You have to consider a lot of factors that suit your particular needs. Here are some tips to help you out.
Watts (W) and Milliamp Hour (mAh)
Solar charger size is either in watts or watt hour (wh), milliamp hour (mAh) or both. Most laptops need 20 to 50 watts, or 20,000 to 50,000 mAh.
To convert watt hour to mAh:
WH x 1000 = mAh
To convert mAh to Wh:
mAh x V (voltage) / 1000 = Wh
If you have a 25000 5V solar charger, the formula is 25000 x 5 / 1000 = 125 Wh
The rule of thumb is to provide allowance for your needs. If you have a 30W laptop, get a 30W-40W solar charger so you don’t push the charger to the limit. Having reserve capacity for your phone or other gadget is another reason for getting extra power. Bottom line: better to have more power than less of it.
Look for a solar charger that offers multiple ways to power your laptop. Ideally you should be able to charge with a solar panel, a wall outlet and a battery pack. Wireless charge is becoming increasingly popular too.
Charging with a solar panel is very common, but it should not be your only option. The other option is to use a power bank (battery) as it is fast and does not depend on sunlight. The solar panel charges the battery which you then use for your laptop. A wall outlet is the fastest option and should be done at home or if you’re in a vehicle. Always charge your laptop to the fullest before going out.
How long does one solar charger last? To put it another way, how many times can you use the charger before it needs to be recharged?
This is an important question especially if you’re going on a long trip. High quality solar chargers can charge a laptop 2 or 3 times on a single charge. This means you can use it to power a smartphone, tablet or other devices numerous times.
Keep in mind that when the manufacturer says a device can charge a phone 8 times, a tablet 3 times, a laptop 2 times, it refers to one device only. That is, you can charge a phone 8 times or a laptop 2 times, etc. Charge time will also depend on available sunlight if you use solar panels.
Charge and Recharge Speed
Look for PD 3.0 support, which is the latest protocol for fast solar charging. Also look for solar chargers that can automatically detect a device’s current and adjust the charge speed for best results.
If you’re only going to charge a laptop, a single compatible output is enough. But since you’ll probably have your phone during camping (and you should), having another port is ideal. Most solar laptop chargers have at least 1 5V USB port and 1 18V DC port.
But most solar chargers have dual USB ports so it’s not an issue. If you have several gadgets or have companions, a solar charger with multiple ports is necessary. Three ports is often enough, but if the charger has wireless support, you have four now.
Solar Charger Durability
A solidly built solar charger is a must. That device will be exposed to dust, rain, dirt, and other particles in the air. It will get a few bumps here and there as well. ABS and hard plastic are good while other manufacturers use proprietary materials.
A durable solar charger must also be shockproof, dust proof and sweat proof. A waterproof and rain proof charger is necessary too. Fortunately you’ll be hard pressed to find a solar charger that isn’t one.
Solar Charger Features
If a solar charger charges your laptop, what else do you need? A basic solar charger gets the job done, but it never hurts to have other useful features built in. Some of the more important are the following:
Most solar chargers have a flashlight which you activate by pressing a button. Aside from a steady light, most have an SOS mode, and some even have a strobe mode. You should always be prepared for anything when camping, so a flashlight with SOS is essential. A built in flashlight also means you don’t have to pack one separately.
A carabiner or eye hole lets you attach the solar charge to a backpack. A lot of campers do this so they can charge the panels on the fly. Another benefit is the solar charger is within reach. No need to remove your backpack and unpack everything just to charge.
The solar panel rating efficiency tells you how quickly your device can be recharged. Average solar panels have a 15% rating, but the best are in the 20% to 23% range. Do not settle for anything less than 20%.
A good solar charger should be able to do more than just power a laptop. It must be compatible with popular smartphone models, GPS, radio, tablets and other electronics. The top laptop solar chargers are all in one chargers and also serve as emergency flashlights.
The level of versatility depends on your needs. Even if you only use a laptop and phone, it doesn’t hurt to have a solar charger with a wide compatibility range.
A feature packed solar charger is useless if you cannot use it intuitively. A plug and play system is the best scenario, where you just plug your laptop and the charger goes to work. Any other extra feature should be easy to use.
The more powerful a solar charger is, usually the heavier. Portability varies from person to person, what is
portable for some may not be for you. If you carry a lot of stuff in your backpack though, every ounce counts. Charging a laptop requires more power than charging a phone, so expect these solar chargers to weigh more.
Warranty and Money Back Guarantee
Buy only from reputable websites and manufacturers. When you receive the solar charger, inspect it immediately and try out the features. Read the warranty and learn how long it is and what the coverage is. You should be able to get a refund if the product is not working properly..
Everyone has specific needs when it comes to laptop solar chargers. Some want maximum capacity, while others put premium on speed. Still others look for compatibility and others for multiple charging capability. Whatever you are looking for, the products reviewed here are up to the task, so you never have to deal with a low battery laptop again.
