Yes! Easily at powered camp sites that have Japan standard 110V mains power. To assist, we provide an extension cable for you to charge the sub battery system installed in our Overland camping cars. As a simple guide where power levels are of high concern, we suggest charging at a powered camp site every 2nd evening of your journey.
Note: While we strive to provide high capacity long life energy systems, we have yet to achieve perfect perpetual energy meaning that the sub battery systems are a finite resource where charging is subject to factors such as drive time, individual use-age (appliances), weather, sunlight etc. An alternative device charging method is available all campers with 12V USB charging ports in the front drivers section enabling an additional method for charging while driving (phones, lights, speaker etc).
For peace of mind our campers engine starter battery systems are independent of the sub battery system meaning the campers will always start in any sub battery level situation.
Pro Tip. For the fridges while on the go tip is to buy a block/bag of ice from any convenience store placing it in the fridge keeping your food fresh until charge is restored. Easy!
