How We Review Products
Last updated: October 2026
Every buying guide on ChargeWiseHub follows the same method. This page explains exactly what we check, what we don't do, and how we decide which product earns a spot.
Who writes our reviews
ChargeWiseHub is written and maintained by Carl Graham, who has worked in construction, development and building inspection in Queensland for more than 40 years. Every guide is put together by him, not by a freelance content team.
What we check before a product is recommended
- Australian pricing. Prices are taken from the brand's own Australian store at the time of writing, not from overseas listings or old press releases.
- Manufacturer specifications. Capacity in watt-hours and amp-hours, continuous and peak output, battery chemistry, cycle rating, charge times and weight come from the manufacturer's own published data.
- Australian compliance. We check for RCM marking, the physical socket type (a genuine Australian 240V outlet, not a US or EU plug with an adapter), and warranty support handled inside Australia.
- Owner reports. Where a model has been in the market for a while we read through buyer feedback and forum threads looking for repeat failure patterns, not one-off complaints.
- Comparison. Nothing is recommended in isolation. Every pick is weighed against at least two comparable products at a similar price.
What we don't do
We do not run a testing laboratory. We do not claim hands-on measurements we haven't taken, and we don't invent lab scores, drop tests or "hours of testing" figures. Where a judgement rests on published specifications rather than our own measurement, the page says so.
Our ratings reflect how a product stacks up for an Australian buyer on specifications, price, local support and reported reliability. That is a different thing from a bench test, and we'd rather be clear about it than dress it up.
How we rank products
Each category is weighted for what actually matters in that category. For portable power stations we weigh usable capacity, continuous output, cycle life, socket type and warranty. For battery chargers we weigh charge profiles, amperage, safety features and whether the brand supports Australian customers. The weighting changes between categories because the buying decision does.
How we make money
ChargeWiseHub earns a commission from Amazon Australia when someone buys through our links. It costs you nothing extra and it does not change where a product lands in our rankings. If a product doesn't earn its spot, it doesn't appear, regardless of what it pays. Full detail is in our affiliate disclosure.
Prices and corrections
Prices in this market move constantly, and stock comes and goes. If you spot a price, specification or claim that's wrong, tell us and we'll fix it. Corrections are made to the page itself rather than buried in a comment.
