The 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 sunlight into energy. At 28 watts, the SolarPowa 28 is a middle-of-the-road panel in terms of wattage.
The SolarPowa 28 is equipped with three USB ports and offers all the charging capacity that one could need while outside. However, it lacks DC charging, so plugging in your laptop or larger device won't work very well.
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 and with 3 USB-A ports.
The BigBlue SolarPowa 28 is a 24-watt monocrystalline folding solar panel that weighs 20.9 ounces and measures 31 inches in length, 11.5 inches in height, and 0.2 inches in thickness when fully opened. It does not have an integrated battery, but it does have three USB ports, each of which outputs 2.4 amps.
【High-efficiency and Durablity】 Using premium ETFE solar arrays, this portable solar panel achieves a conversion rate of up to 25%, maximizing free energy from sunlight.
