  • Nice thing for my diesel car battery

    posted by matolegin2

    I bought two pcs and connected paralelly together through diodes. So I have in load 14 V but 16 W. Together with 10 A regulator is connected to car battery. Auto battery is charged every day when is sunny but little also when is cloudy. I have always fresh battery and starting is no more problem. More watts = more strong battery and best conditions for starting car. Be aware and use proper connections and fuses. Panels are mounted on front window (always) i must not do anything, charging is automated and in night the charger will stop and automatically disconnect battery.
  • Very good!

    Works very well. Bought to outfit my bike and I was surprised with the ease of installation. Bring everything you need to install and use. Brings two magnets for easy mounting, if you want to place the sensor in the right or left side of the wheel. Works well in the presence of sunlight and retains data for long time without battery.English manual with clear instructions.
    Small but powerful device. I will ask others for gifting.
  • Good backup battery

    posted by junimrox

    --> Very small, smaller than I thought
    -->, good for carrying around and using as a emergency battery for mobile phones, ipods, mp3 players, digitalcameras etc.
    --> it's solar powered, so you have free electricity!
    --> it may be recharged by the usb of pc when there is no sun laying around
    --> Lithium batteries, veeeeeery good
    --> it outputs 5,45V which is way good!
    Good, buy one if you have lots of usb things.
  • 12000mAh Portable Solar Power Battery Pack with Laptop & Cellphone

    posted by SickMF

    Very useful thing. Has great capacity and many outputs to satisfy all necessaries. Not so bad plastic case has no backlash. Not so heavy as I expected. Charger indicates when battery is fully charged and it`s very useful.
    Now I can travel without thinking how I can recharge my phone or photo camera. I can use my laptop for 3 to 4 hours longer. So, if you have to trvel, this is the perfect thing for you.
    It is a pity, I can`t actually measure up the real capacity.
  • Godd ratio price/quality for the money

    posted by budiony

    The product has good quality/money ratio, comes with alligator clips and cigarette lightning jack for charging battery directly from your cigarette lightning inside a car, but you need to have a voltage in this jack when the keys are off and engine is not running, otherwise use the alligator clips.
    It appears after measuring the voltage with multimeter that it is around 16.5 Volts under direct sun light, the optimum voltage however for charging lead battery is 1.5 times the output voltage, in cas of 12 Volts that means that you`ll need 18 Volts.
