(2 PCS )45W Car USB Charger with Dual QC3.0 Fast Charging Ports - 12-24V Vehicle Power Adapter

A panel-mounted charger gets fitted once and then forgotten, so the five minutes before the hole saw comes out matter more than anything afterwards. Two questions decide the job: what the vehicle's supply actually is, and how much the unit will hand over when both ports are busy.

A 40 mm body and two QC3.0 ports

The supplier gives the body as 40 mm x 37 mm without its cover, small enough to drop into a blank switch position or a spare dash aperture. Both sockets are QC3.0, the fast-charge protocol that most Android phones, tablets and navigation units will negotiate. Over the top sits a cover the supplier describes as waterproof, which is what separates a fitting that lasts on a boat or a motorbike from one that greens up. Wiring is stated as included.

12 V or 24 V, and the fuse on the lead

Compatibility is given as 12–24 V systems, which takes in a car, a ute, a motorbike and most truck and boat installations without a converter in between. The supply lead carries a 10 A fuse for overload protection over an 80 cm run. Be clear about what that fuse does and does not tell you: it is a protection rating for the circuit, not a statement of output, and it settles nothing about the wattage question below. Read it as the limit the wiring is protected to.

Key features

• Dual QC3.0 sockets: both faces support the same fast-charge protocol, not one fast and one slow.
• 12–24 V input: one part number covers passenger cars and 24 V trucks alike.
• 10 A fused lead: overload protection built into the 80 cm supply run.
• Cover over the faces: described by the supplier as waterproof, for open cockpits and bike fairings.
• 40 mm x 37 mm without cover: fits a blanking plate or a spare switch cut-out.
• Wiring supplied: no separate loom to source before fitting day.

Two things to settle before you order

First, the 45 W is never attributed. Per port, each, total and combined appear nowhere in the supplier's text, so whether 45 W is available at every socket or shared between them is undetermined, and we will not decide it on your behalf. If you are sizing this to fast-charge two devices together, check with us first. Second, the listing sells a two-pack while the specification describes a single unit — dimensions and fuse are both given in the singular. Confirm the count with us before you order.

• Fuse the feed at the battery end as well, sized by whoever does the install to the cable you actually run.
• On a 24 V truck, verify the fitting is wired to the accessory circuit you intend and not a permanently live feed.
• The cover only helps when it is closed. In a wet cockpit, shut it when nothing is plugged in.

In the pack

• 2 × 45 W car USB charger, as the listing sells it; the supplier's specification describes one
• Included wiring, with a 10 A fuse on an 80 cm lead

A compact fused charger for a 12 V or 24 V panel. Confirm the wattage and the pack count with us and the fit is straightforward.
