Not yet used it in a camping environment, but on receipt immediately plugged it in at 22.5 deg ambient and within 3 hours it was down to 5 deg. Will be fully testing it in a few days time down in Italy. Happy to report back later....

I ordered 5 minutes before the cut-off time and still received my order the next day. The only issue was that I never received an order confirmation email or a dispatch email so I wasn't sure that my order was successful until I received the courier notification the next morning.

Speedy delivery. Product as expected. Would recommend this company.
