There is no built in battery, but it has three USB ports which allow you to plug in and split the current between 3 devices at once.

The BigBlue charger delivers a steady energy flow even on cloudy days so you can confidently plan your outdoor activities without having to worry about low battery devices.

This solar charger is made of four SunPower solar panels sewn into a durable canvas and a fifth section that’s more like a small pouch for storing your iPhone or Android phone while charging and thus protecting them from the direct sun exposure and overheating – however, if you have a cable long enough, it’s always better to move your devices into the shade. You can also easily store all the cables in this department.

Inside the pouch there are three USB ports that deliver up to 2.4A per port or 5V/4A overall (depending on how much direct sunlight hits the solar panels), and a small LED that indicates when there is power flowing from the panels.

The Nekteck 28 watt solar charger is essentially indistinguishable from the BigBlue without the branding. The specs are similar. Opened up, and without the ammeter, they look essentially identical, too. 

However, in the end, it didn’t perform quite as well as the Big Blue even though it uses the same solar cells and design. In relatively similar conditions, the Anker produced 733 mAh, and the Nekteck produced 834 mAh. It also has a claimed weight of 1 pound, 7 ounces two ounces heavier than the Big Blue. 

What to Look for in a Portable Solar Charger 

Water Resistance

If you are shopping for a solar panel, it is a good idea to look for water resistance in case you unexpectedly get caught out in the rain because solar power comes from the sun, and solar panels work best outside.

Built-In Battery

Solar panels generate power, and that power has to go somewhere. If you just have a solar panel and nothing plugged in, the panels will not generate power, which is fine, but a battery would allow you to not only generate power, but store it until you need it.

Power Output

Have in mind the types of devices you will be using. If all you need to charge is a phone or tablet, most solar panels will be able to do the job. You will need to make sure you have got a setup powerful enough to get the job gone If you need to power something larger, such as a laptop or even a car.
