Wilson Antennas 305POWERCUP 12V 2+2 power inverter with phone holder

SKU CH-Z18J-QHPET

Powers two 12 V sockets, one 1 A and one 2.4 A USB port with 3.4 A total, plus a 360-degree rotating phone holder and 10 A fuse in a cup-holder design

  • Powers two 12V and two USB devices at once
  • 360-degree rotating holder secures phone or GPS in view
  • Fits most cup holders for tidy in-car placement
  • Blue LED shows power status at a glance
  • Replaceable 10A fuse protects the 12V supply

Power Delivery

The Wilson Antennas 305POWERCUP plugs into a 12-Volt vehicle socket and provides two 12-Volt outlets plus two USB ports. A 10-Amp replaceable fuse protects the circuit while a blue LED shows power status. The unit sits in most cup holders for a tidy installation.

Phone and GPS Mount

A 360-degree rotating holder keeps a phone or GPS device in view while driving. The design suits commuters and road-trip drivers who need charging and visibility in one spot. It does not suit users who require AC outlets or higher amperage than the 10-Amp limit allows.

Capacity and Limits

The two USB ports deliver 1-Amp and 2.4-Amp outputs with a combined 3.4-Amp maximum. All connected devices must stay within the overall 10-Amp rating. Exceeding that limit will blow the fuse and cut power to every port.

Questions about this item

Does the 305POWERCUP plug directly into a 12‑volt accessory socket?

Yes, the included 12‑volt power cord connects to a standard vehicle accessory socket and carries a replaceable 10‑amp fuse.

Can I keep using my existing 12‑volt accessories while charging two USB devices?

The unit provides two 12‑volt sockets plus one 1‑amp and one 2.4‑amp USB port with a combined 3.4‑amp USB output, so all four ports work together.

How do I confirm the inverter is delivering power after I plug it in?

A blue LED on the housing lights up when the unit is receiving power and the fuse is intact.
