Gary & Arnies 69k trek - Solar Bank Phone Charger

Had to send 1st unit sent back as it was possibly faulty

Company Mobile Solar Chargers was very good and sent replacement before receiving other one back and it was delivered next day.  They have also sent me a Travel and Trek 12w solar panel charger to trial so will test that separately.
