Tractive dog tracker charger?

Afternoon Aberdeen!

We're due to arrive in West hill tomorrow.

We have our 4 legged beastie with her tractive tracker with us.

Whilst making sure we have everything we need for the week, we've arrived at our halfway stop in the borders, I'm sitting here in the sun with a pint of thistly cross and looking at the dog, and realised I've forgotten the charging clip for her tracker.

Anyone lend me theirs for an hour to charge?!

Or alternative suggestions welcome!

Thanks.
