170W USB-C Car Charger (4-in-1)

One 12V socket becomes four powered devices — 2x USB-C PD, USB-A, and a passthrough socket so the dash cam stays plugged in.

The modern cab runs on USB: phone, tablet, GPS, headset, dash cam — and the truck gives you one 12V socket and a couple of trickle-speed USB ports to feed all of it. The 170W 4-in-1 car charger (model C82) fixes the math: 170 watts shared across two USB-C PD ports and a USB-A port, plus a passthrough 12V socket on top of the head so whatever was plugged in before stays plugged in. Four devices, one socket, zero cable archaeology.

How it works

Plug in, load the ports, drive

Plug it in

Push it into the 12V socket like any plug. The head sits low and compact, with the ports facing up and the passthrough socket open on top.

Load the ports

USB-C PD for the laptop or tablet, USB-A for the phone or headset, and the dash cam or GPS puck goes in the passthrough socket. Everything that was powered before stays powered.

Unplug at shutdown

At 2.46 ounces it pops out in a second. Pull it when you shut down and there's zero standby draw on the truck batteries overnight.

Why 170W beats the dead-socket shuffle

The truck's built-in USB ports are trickles — fine for holding a phone's charge, useless for filling a tablet or feeding a laptop. A cheap 30W plug improves on that but still forces a choice: charge the phone OR the tablet, and the dash cam gets evicted from the socket either way. The 170W pool ends the choosing: laptop on one USB-C, phone on the other, headset on the USB-A, and the dash cam never leaves the passthrough socket.

The objection is usually "I don't need that much power" — but the charger doesn't push 170 watts into anything. Each device negotiates what it needs over PD, and the headroom just means the laptop doesn't starve the phone. Buy the capacity once instead of buying the small charger now and the big one later.

Buyer questions

What drivers ask before buying

Will this charge a laptop in the truck?

Yes, over USB-C — that's the point of the PD ports. The 170 watts are one shared pool, so plug the laptop in first and let it negotiate what it needs, then add the phone and GPS after. Running a laptop plus two phones at full tilt splits the budget, but for the usual cab mix — laptop working, phone topping up — there's headroom to spare.

What does “4 devices at once” actually mean?

Three USB ports plus the passthrough 12V socket on top of the head. In practice: laptop and phone on the USB-C ports, headset on the USB-A, and the dash cam or GPS puck still plugged into the passthrough socket. Nothing that was powered before gets evicted.

Will it drain the truck batteries if I leave it plugged in overnight?

Any 12V accessory can sip standby power, and truck batteries are expensive lessons. This one weighs 2.46 ounces and pops out in a second — make pulling it part of the shutdown routine, same as locking the doors. No standby draw if it's in your pocket instead of the socket.

Does it fit a standard truck 12V socket?

Yes — standard cigarette-lighter form factor, and the head is compact at 4.41 by 3.19 by 1.61 inches. It seats in the dash socket the same as any plug, with the ports facing up where you can reach them from the driver's seat.

Is 170W overkill if I only charge a phone?

No — the phone draws only what it negotiates, never the full 170. The headroom is for the day you add a tablet, a second phone, or a laptop to the mix. Buying the small charger first and the big one six months later costs more than buying the big one once.

Here's the part that matters: every device in the cab is fighting over one socket, and the losers are the ones you need most — the GPS dying mid-route, the phone crawling at trickle speed. A 170W 4-in-1 ends the fight for the price of a plug: four devices powered, the dash cam never evicted, and nothing to wire.

One 12V socket feeds the whole cab — the charger just has to keep up.
