### ⭐⭐⭐⭐⭐ 







  
  
    Great Value Solar Charger.
  

*by S***Y on Reviewed in the United Kingdom on 7 May 2014*

Bought this over the bank holiday and it arrived on the wednesday after so top marks for delivery.Decided to give it a "test run" yesterday by using the cig lighter plug to connect it to my jump pack. Before connecting i checked the voltage of the jump pack using its own built in voltmeter at 13.4V and 13.2V with the light on (it has a built in work light) and left the jump pack and the solar panel in the car overnight. Today the battery now reads 13.8V and 13.7V with the light on. So it has definitely charged it up.Later i will make a connector so i can leave it plugged into the car when i'm not using it for a while but so far, so good.

    great product 4watt folding solar panel
  

*by A***Y on Reviewed in the United Kingdom on 31 August 2013*

i do camping using a motorcycle.i charge a large nicad battery(out of one of those jumpstarter thngs)using this panelthen run small inverter off the battery to charge phone run laptop lights.strong great value easy to store on motorbike.i set it up charging my battery in day while i am out on my bike.then use battery at night for all electric bits.the only downside is position of connector in front panel which is prone to water ingress when rains.i am afraid a bit of duck tape is need but for price great.buy a double lighter double socket the use a phone charger direct.will charge a iphone using the panel without any other battery  in between

    Solar briefcase
  

*by R***H on Reviewed in the United Kingdom on 15 August 2012*

So far so good,it seems to do the job. I have a 12v battery in the garage that I usefor charging phones ,shavers ,rechargeable batteries etc.This solar briefcase is proppedup in the garage window and even in this poor summer weather it keeps the battery toppedup. We also use it on the dashboard of our motorhome to top up the leisure battery when weare away on holiday.It is well made and fold up design means the panels are protected whennot in use.
