Samlex SAM-250-12 - 250 Watt Modified Sine Wave Inverter, 12V, Outlet + USB

Sometimes the whole requirement is one outlet and a USB port that work in the truck. The Samlex SAM-250-12 is a 250 watt modified sine wave inverter the size of a paperback: one three-prong outlet, a 2.1 amp USB port, and both connection cables, lighter plug and battery clamps, in the box. Under a pound, under a hundred dollars of hardware, and enough for the chargers, lights and small electronics that ride along every day.

Warranty

Warranty. Samlex America warrants the SAM-250-12 for 2 years. Full terms are confirmed in writing with your quote.

The Everyday Carry of Inverters

Under a pound
At 0.92 pounds and 5.9 inches long, it disappears into a console or glove box until the day it earns its spot.
Outlet plus fast USB
The NEMA 5-15R runs the corded device while the 5V 2.1A USB port charges a phone or tablet at full speed.
Frugal by design
90% peak efficiency, 0.2 to 0.3 amps at idle, and a fan that stays off below roughly 10 watts of load.
  • Lighter-plug and battery-clamp cables included; nut-and-bolt DC terminals with a 30 A fuse.
  • Universal protection circuit: low voltage alarm and shutdown, high voltage, overload (latching), over-temperature and leakage shutdown.
  • Soft start and cool surface designs from the same SAM series as the larger models.
  • ETL listed; low-interference operation near radios and screens.

Where This Inverter Is Used

  • Daily drivers - phone, tablet and camera charging between stops.
  • Trucks and RVs - lights, small stereos and chargers off the 12V system.
  • Boats and camps - one outlet of AC without a wired system.
  • Glove-box emergency kits - charge anything from any 12V battery.

Ordering

Entry point to the range. This is the least expensive inverter we carry from Samlex; the SAM-450-12 adds a second outlet and doubles the wattage for a small step up, and the pure sine PST-150-12 covers sensitive loads. Quantity buyers get a written quote in 24 to 48 hours.

Frequently Asked Questions

Is 250 watts of modified sine enough for a laptop?

Usually. Most laptop power bricks tolerate a modified sine waveform and draw well under 250 watts. A minority of pickier adapters will buzz or run warm on it; if yours does, or if the laptop is mission-critical, the pure sine PST-150 and PST-300 models remove the question.

How do the two included cables divide the work?

The cigar-lighter plug handles grab-and-go duty for lighter loads, limited by the vehicle's socket fuse. The battery clamps carry the full 250 watts, which draws up to 25 amps, straight from the battery posts.

What happens if I plug in too much?

The inverter latches off rather than cooking itself; flip the power switch off and on to reset. There is a 500 watt one-second surge allowance for switch-on spikes, and over-temperature events reset on their own.

SAM-250-12 or SAM-450-12?

The 450 doubles the outlet count and nearly doubles the power for a few dollars more; the 250 is smaller and lighter still. Same USB port, same included cables, same 2 year term on both.

One outlet, one USB, always in the truck.
