Samlex PST-120-12 - 120W Pure Sine Wave Cigarette Lighter Inverter, 12V, USB

When the device you plug in is a CPAP or a piece of medical equipment, the inverter's paperwork suddenly matters. The Samlex PST-120-12 is a 120 watt cigarette lighter inverter listed to ANSI/AAMI ES60601-1, the safety standard for medical electrical equipment, which is why it is approved for hospital settings most plug-in inverters never see. It draws from any 12V accessory socket through the included cord-set, delivers true sine wave AC from a single outlet, adds a USB port, and slides into a door pocket at 1.2 inches thick and one pound.

Warranty

Warranty. Samlex America warrants the PST-120-12 for 3 years. Full terms are confirmed in writing with your quote.

The Plug-In Inverter With Credentials

Listed for medical settings
ETL listed conforming to ANSI/AAMI ES60601-1 and approved by Samlex for hospital applications, a bar the gas-station inverter aisle does not clear.
Genuinely pocketable
At 4.13 x 7.44 x 1.2 inches and one pound, with a quiet temperature-controlled fan, it travels in a laptop bag without announcing itself.
AC and USB together
The sine wave outlet runs the sensitive device while the USB port keeps a phone alive from the same socket.
  • Pure sine wave output, under 3% THD, 120 VAC within 3 percent at up to 1 amp.
  • Cord-set included: 2 ft detachable cable with 12V plug adapter; external replaceable 15 A fuse.
  • Self-recovering overload: output voltage folds back rather than shutting down, and recovers when the excess load is removed.
  • Three-color LED reports operating state and faults at a glance; FCC Part 15(B) Class B.

Where This Inverter Is Used

  • Medical device users on the road - CPAP and similar equipment under 120 watts, on a listed inverter.
  • Cars, trucks and RVs - laptop and small-electronics power from the accessory socket.
  • Home care and patient transport - applications that require ES60601-1 compliance.
  • Travel kits - one pound of AC and USB in the laptop bag.

Ordering

Know your wattage first. If the load list passes 120 watts, step to the PST-150-12 or PST-300-12 with their clamp cables and surge headroom. For home-care fleets and medical suppliers ordering in quantity, a battery specialist returns a written quote in 24 to 48 hours with your count and ZIP.

Frequently Asked Questions

Can I run a CPAP or other medical device on it?

The PST-120-12 is ETL listed conforming to ANSI/AAMI ES60601-1, the medical-electrical safety standard, and Samlex approves it for hospital applications. Check that your device, including any heated humidifier, stays under 120 watts, and confirm suitability with the device manufacturer for clinical use.

Why does the surge rating equal the continuous rating?

Because there is no surge headroom in this design: everything you plug in, startup included, must stay under 120 watts. Electronics running on AC adapters live comfortably inside that. Anything with a motor, compressor or heating element is the wrong load for this inverter.

How does it connect to the vehicle?

A 2 foot detachable cord runs from the inverter's modular connector to a 12V plug that fits any lighter or accessory socket. Protection is an external, replaceable 15 amp mini blade fuse, so a blown fuse never means opening the case.

What does the USB port supply?

5 volts at 500 milliamps, a standard phone-charge trickle, with its own overvoltage shutdown at 6.2 volts. For faster charging, use the AC outlet with your device's own adapter.
