The BigBlue 28W solar charger weighs 1.25 pounds, attaches to a backpack or bicycle bags, and can charge up to 3 USB-rechargeable devices at once. On sunny days it provides ample power to keep multiple smartphones charged indefinitely. In cloudy weather it charges slower but still makes progress.
The maximum nominal / rated output of the SolarPowa 28 solar charger is rated based on the Standard Test Conditions (STC) – the industry-wide standard for the conditions under which a solar panel is tested. The test conditions are defined as irradiation 1000 W/m², temperature 25°C, and air mass 1.5.
Whether you are charging on a partly cloudy day or the sun angle changes to cast a shadow over the panel while charging, the BigBlue SolarPowa 28 continues to put out more power than the rest. This model kept chugging along in less ideal conditions, effectively charging its test batteries and the rest of our tech.
If you’re car camping you can get better performance with a bigger panel, but the BigBlue 28W would still be helpful, especially if you lay it out in direct sunlight. It would also work well for travel to places with unreliable electricity, as it’s thin enough to pack easily into a suitcase.
The SolarPowa 28 is a reliable and easy-to-use portable solar panel. The BigBlue SolarPowa 28 performed exceptionally well in direct solar charging tests, outdoing the other solar panels with its four strong solar panels linked together. This panel is extremely effective at converting direct sun into energy.
The previous version, the BigBlue 3, came with an ammeter to monitor power output. The SolarPowa 28 is available both with and without an ammeter, allowing you to choose if you want to carry the extra bulk or not. We tested the version without the ammeter. Anker Solix 30W Fol...
