What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: the title says 12V/24V and 25A, the feature text claims 12V 25A / 24V 15A, while the details list 24 Volts input and 25 Amps without clarifying whether that input figure describes charger supply or battery output. Confirm the correct supply and charging output for your battery before buying. The title says fully automatic, while the feature text also describes five selectable current levels. The listing says never to use Repair or Boost modes on lithium batteries, so use standard charging modes for lithium as directed.

Who is it for?

A good fit for

Drivers and owners of utes, 4WDs, SUVs, boats or caravans seeking a charger with selectable current settings.
Buyers who need a charger listing compatibility with both lithium and lead-acid battery types and can follow its mode restrictions.

Less suited to

Buyers who need an unambiguous, confirmed 24V charging output before purchase.
Anyone seeking a charger whose package contents, plug type or cable reach are clearly specified in the supplied listing details.

The supplied rating information is entirely five-star, but it comes from only four ratings and includes no written customer feedback. That small aggregate gives limited guidance about real-world charging results, battery compatibility or usability, so buyers should rely on confirming the listed electrical details and operating restrictions for their own setup.
