The firm now offers five of its off-grid charging devices to CAMC members at privileged prices.
This follows a deal with the Royal Yachting Association and gives the business access to more than one million campers, tourers and sailors.
Launched last year, Powercases (Scotland) has a partnership to exclusively represent the Canadian Powercases brand of lithium-ion rechargeable power packs and cases in Europe.
MD Peter Waggott anticipates the firm will agree further deals later in the year.
He said: “Having power on demand when you’re travelling or at a camp site without mains power for campers is essential these days given how reliant we are on our mobile phones and laptops.
“We’re very pleased to have linked up with a third trusted brand and expect to be announcing more similar agreements in other sectors this year.”
