Carl Graham
Carl Graham is the founder and writer behind ChargeWiseHub.
Background
Carl has spent more than 40 years in construction, development and building inspection in Queensland. That working life means decades of dealing with 12V gear that has to actually work: work utes with dual-battery setups, caravan and camper power, site equipment, jump starters that get used in the rain, and chargers that either survive a Queensland summer or don't.
He started ChargeWiseHub in 2026 for a simple reason. Buying a battery charger or a power station in Australia meant wading through reviews written for American sockets, with prices from overseas stores and no mention of whether the thing is even sold here with local warranty support. ChargeWiseHub exists to answer the Australian version of the question.
What he covers
- 12V charging and dual-battery systems for 4WDs, work utes and caravans
- Portable power stations and solar charging for camping and site work
- Jump starters and emergency gear that has to work first time
- EV home charging, from single-phase to three-phase installs
- Phone, laptop and device chargers, including what overheats in an Australian car
How the guides are put together
Every guide follows a published method. In short: Australian pricing from the brand's own store, manufacturer specifications, local compliance and warranty checks, and comparison against at least two rival products before anything is recommended. We don't claim lab testing we haven't done. The full method is on the how we review page.
