Powerenz FireFly Ultralight Portable Solar System is compact & lightweight. This product has a lithium battery with a fuel gauge, and comes with a 4.5-watt, 5-watt, or a 20-watt solar panel.

Specifications:

FireFly Ultralight can be carried where power and minimal weight are important, is best suited to provide power for smaller electronics, and is light enough to carry during mountaineering or backpacking expeditions. This system can power electronics that require 12 volts DC up to 5 amps/55-60 watts, 5-volts USB up to 2.1 amps using an optional USB adapter, and can recharge itself in sunlight using the included foldable solar panel. If the power draw on the battery is 10 watts, the battery will last approximately 3 hours in the absence of incoming solar power before it needs to be recharged. The battery and other components are enclosed in a padded MOLLE hip/shoulder bag/pack in khaki, olive drab, or black. The folding solar panel, USB adapter, and AC-powered battery charger remain outside of the pack. 12-volt DC power is accessible via a cigarette lighter socket. USB charging power is provided by an optional adapter that plugs into the cigarette lighter socket.

FireFly Ultralight includes:

Battery - a rechargeable, 11.1-volt, 3.5 amp-hour, 38 watt-hour, lithium polymer unit. The protective circuitry limits the maximum discharge current to 5 amps. The battery can be charged directly from the solar panel, or via the smart, 1.5-amp, 100-240VAC-powered charger when the grid is available (4-4.5-hour charging time). To charge the battery via a wall AC outlet, the AC-powered battery charger plugs directly into the cigarette lighter socket; Fuel gauge- the battery comes with a push-button fuel gauge that indicates the remaining energy of the battery via a series of red LED's; Solar panel - see a brief description under each one of 3 choices; Solar Charge Controller - 4-amp/50-watt MPPT unit. If the system is stored for a prolonged period of time, the battery should be charged every 1-2 months in order to avoid complete discharge; and, Carrying bag/pack/case – MOLLE hip/shoulder bag/pack in black, solid khaki, or olive drab that measures 8 x 6 x 4 inches in external dimensions.

The optional USB adapter plugs directly into the cigarette lighter socket and has two Type-A USB charge ports - one that provides 1 amp of current, and the other that provides 2.1 amps of current for an iPhone, iPad, Tablet, or other USB-charged devices.

The AC-powered charger will not be needed when the system is used off-grid, and the system then weighs 2.3 pounds.

For those who require added protection against damage, dust, or water, this same system comes in an optional waterproof hard case.
For those who would like to recharge the battery more quickly, we can discuss a larger solar panel. Please call 770-639-2244 for customizations.
