I am always on the lookout for new and innovative products that can make my life easier, and when I came across the BigBlue 28W SunPower Solar Panel with Digital Ammeter, I knew I had found something special. This solar panel charger is not only incredibly efficient at charging devices, but it is also portable and easy to use. Plus, the digital ammeter allows you to keep track of your power usage so that you can optimize your charging efficiency.
My Experience With Bigblue 28w solar charger
This solar charger is great – it charges two devices at 2.3-2.4 amps and can recharge two 10,000 mAh power banks in just a few hours. We took it with us on a trip to Yosemite and it worked perfectly, providing charging power for our devices while we were hiking.
It would have worked even better if we’d left it in the camp, as the angle of the sunlight wouldn’t have been as good when attached to the backpack, but it still did the job well.
About Bigblue 28w solar charger
The BigBlue 28w solar panel charger can measure the current value in real-time, making it more convenient for you to use. It also has sunlight intensity and the used cable. If your device has a limited input current of 1A (such as the iPhone), the amount of ammeter will show between 0.8A and 1A in theory.
