BigBlue SolarPowa 20 – USB Charging for the Campsite and Beach

Our RV travels take Joan and I to places where there’s no power for our devices such as cell phones, tablets or our Internet hotspot. For the past year, we have used the large power stations for supplemental power and they have worked great, but they are large, bulky and heavy for short trips when we need to charge our phones. We now have an alternative, the BigBlue SolarPowa 20 portable solar panel with two USB ports. With the SolarPowa 20, we can head to the beach or a weekend outing, pack light and keep our phones and tablets charged.

The BigBlue SolarPowa 20 is light weight and fits easily in a backpack or carry bag. The panel weighs 1.7 lbs and folded is 9” X 9” and with the attached USB power connection is 1.5″ thick. Open, the panel is 26” X 9”.

The back of the solar panel contains the USB charger with a USB Type-A and a USB Type-C connection, both rated at 5V and 2.4A. Also on the back is a folding arm that fits flat when stored and can be open to act as a kick stand to gain the best angle for sun exposure. We also like the reinforced eyelets on the corners where we can hang from our tent when we spend the day at the beach.

  • WEATHER- PROOF: Weather-proof with a 10-year performance warranty.

Testing the BigBlue SolarPowa 20

We wanted a bright sunny day to test the BigBlue SolarPowa 20, but after two weeks of rain and overcast skies, decided to give the panel a real world test during a partly cloudy day. We expected this would be a challenge for the panel, but perfect sunny days aren’t always available when we travel and we need to charge our phones.

For the test we used a Samsung 8+ cell phone and a Samsung 8” tablet. The phone was completely discharged and the tablet was at 26%. We connected both devices using a USB cable to the BigBlue SolarPowa 20 and gave the panel 3 hours to charge. During the test, we experienced several large clouds obstructing the sun from panel for short periods and estimate full sun for about half of the charging time.

At the end of 3 hours hours, the phone battery charged from 0 to 63% and the tablet charged from 26% to 81%. We didn’t use the devices during the charge, but background tasks continued including messaging and emails.

Conclusion

We found the BigBlue SolarPowa 20 to be a light weight, easy to deploy solution when we need USB power for our communications and entertainment devices. Even in less than optimal sun, the panel provided enough power to charge our devices with power to finish our day of travel.

Our thanks to BigBlue for providing the device for our evaluation. We have provided helpful links below for more information about this unit and how to purchase for your next RV outing.
