First time poster. Located in Canberra (might know us as Beetle Exchange) The Thunder Weekender battery box is up against Arkpak AP730; better price, 300w pure sine vs mod sine, 2 x Accessory sockets (cigarette lighter) & 2 x Merit Accessory sockets (no merit Arkpak) Suitable 12v batteries are LEAD ACID, GEL, AGM and CALCIUM and will accommodate batteries rated 60 – 160 Amp hour.
The Thunder battery box is a 12V battery charger, portable power station, battery management system and a dual-battery system all rolled into one. A great alternative to wiring your car with a dual battery system and it's portable - Portable 240V and 12V Power. Camping power to your lighting, portable fridge, smart phone and laptop all at once.
I must be missing something. This seems to be just a charger, a 300w inverter, and a box. No battery. And $429.
Can't I buy the same set of devices for half that price?
