RAVPower 24W Solar Panel Charger 3 USB Ports RP-PC005 Review
Product Link: http://amzn.to/2t211eL
Constructed with premium SUNPOWER solar charging cells that have an increased charging efficiency of 21.5% – 23.5%, you can power your portable devices from sunrise to sundown whenever you are outside.
Light and Portable
Chunky and cumbersome solar chargers are a hassle to carry, set up, and use. For something much easier, this 26.4 oz (754g) solar charger is half the size of similar chargers yet capable of generating just as much energy without the extra baggage.
Charge Smarter
iSmart technology automatically detects and delivers the optimal charging current for any connected device, ensuring the fastest and most efficient charge. When under direct sunlight, all three ports are individually capable of reaching 2.4A; with a total of 4.8A being reached when all three devices are simultaneously charging.
Power for All
Having an option for more than one USB port can result in an uneven distribution of power where one device charges faster than the other. With our built-in Smart IC chip, the flow of energy is regulated resulting in every device charging at an even and constant rate.
Hang It High or Lay It Low
Whether you’re placing it on the ground, stretching it across a tree, or hanging it off your backpack via the four stainless steel hooks, as long as it’s directly under the sun, your devices will charge. When outside and the elements suddenly turn on you, the waterproof nylon covering protects the solar panels while the pouch ensures your devices stay dry.
What’s In the Box:
1 x RAVPower 24W Triple-Port Outdoor Solar Charger
4 x Stainless Steel Hooks
2 x Micro USB Cables
