- Wagan Tech SlimLine 1000 Watt Inverter:
- Our SlimLine 1000 Watt Inverter is high output, compact, and slim; hence the reason it is in our Slimline family of power inverters. We have dubbed this line “Slimline” as all of the inverters are high performance but as slim and compact as possible. Featuring 3 US standard AC outlets, Power and fault LED Lights, USB Power Ports, Power switch and thermal cooling fans, the SlimLine 1000 Watt Inverter is ideal for your high power needs!
- Features:
- Taking cues from its big brother, the SlimLine 1000 Watt Inverter is small in size, but offers huge performance. 1000 Watts of TrueRated power, 3 AC receptacles (wall power outlet) as you’d find in your home, 2 USB Power Ports, thermal cooling fans, and a slew of safeties built in, the SlimLine 1000 Watt Inverter is exactly what you’ve been looking for!
- Front Component Details:
- On the front of the SlimLine 1000 Watt Inverter you will find 3 standard US 3-prong AC outlets, 2 USB Power Ports (5V, 3.0A shared), Red fault LED light, Green Power LED light, Cooling Vents, Power switch, and the front mounting flange.
- Rear Component Details:
- The rear of the SlimLine 1000 Watt Inverter offers: Black (Negative) threaded battery terminal, Red (Positive) threaded battery terminal, Neutral to ground bonding terminal (wing-nut), mounting flange, and the two thermal cooling fans.
- Performance:
- Wagan Tech builds our inverters with high peak surges that allow up to 3x the continuous rating to support high surging appliances such as power tools, microwaves, air conditioners and refrigerators. Wagan Tech uses top quality components and reliable MOSFET transistors – the key factor in reliable inverter manufacturing.
- TrueRated Power:
- TrueRated Power is Wagan Tech’s coined term for truth in advertising and performance. While actual output wattage of competitor’s inverters varies greatly, Wagan Tech inverters help consumers to understand and trust that the number printed on the inverter is the actual output of the device.
- Nearly all of Wagan Tech’s Inverters feature TrueRated Power. Simply put, our inverters are tested at full load and will sustain that continuous load for 24 hours at the wattage printed on the inverter. For example, our Elite 400 Watt Pro Inverter will run for 24 hours straight with a 400 Watt load. Our competitors claim “continuous wattage” when in fact most are only rated at 20 minutes of “continuous” wattage. After 20 minutes, the competitor’s output wattage will drop down by as much as 25% of their claimed wattage (in a 400 watt inverter, that can be a 100 watt loss!).
- The Right Output for your Needs:
- Finding an Inverter that can satisfy your power needs may seem like a daunting task, but it really isn’t. Take a look at this basic chart to see what the requirements of an appliance is, and compare it to the Inverter we suggest you use to power that appliance (the appliances listed are estimated averages, please consult your appliance manufacturer for actual power requirements).
- 1000 Watt Applications:
- In your vehicle, boat, motorcycle, RV, truck, Camper, tail-gating, camping, kid’s soccer games, or anywhere you need to turn DC (battery) power into AC (household) power is where the SlimLine 1000 Watt Inverter will shine! 1000 continuous watts means that you can run your appliance without worry of the SlimLine 1000 Watt Inverter letting you down like lesser inverters. Blender, TV, gaming systems, refrigerator, microwave, computer, cooking appliances, and other household electronics are all able to be powered!*
- What It Does:
- If you are apprehensive of using an inverter, don’t be! Inverters simply convert DC current to AC current; in simple terms, it allows you to use your home (AC) appliances using your vehicle’s (DC) electricity. Want to use your blender, box fan, microwave*, TV*, radio, computer*, or just charge your devices while camping or tail-gating? An AC Inverter will allow you to do just that! Connecting an inverter is equally as easy; usually it is just two color-coded wires screwed on to your vehicle's battery. That's it!

The Thick Red and Black Spaghetti of Power
Size: 20FT Black & 20FT Red
If electricity had highways, this would be an interstate.
The cable feels substantial, the copper conductors are flexible enough to work with, and the included lugs and heat shrink tubing make installation easier. Great for batteries, inverters, solar systems, RV electrical upgrades, marine projects, and welding setups.
Voltage drop stays low thanks to the heavy gauge construction, and the insulation feels durable enough for demanding environments.
Overall, a solid wiring kit that inspires confidence when moving serious current.

Great cable kit.
Size: 20FT Black & 20FT Red, Size: 20FT Black & 20FT Red
Great heavy duty cable. Good thick feeling insulation that looks the real deal. Wire is soft enough to route easily without too much resistance. Appreciate it coming with the lugs and heat shrink instead of you having to source extras. Seems to be truly copper as listed. Great deal for the length if so. Worked for what I needed on my UTV.

Cheap price for the cable and terminal ends with heat shrink.
Size: 20FT Black & 20FT Red
Good 6 gauge wire, jacket seems sturdy and like it won't crack easily over time like some wire.
Comes with all the connectors shown too so you don't need to find end ring connections to terminate the ends.
Just need a punch or crimp tool for the terminals but if you already have that then just cut your wire length and add the ends for battery cable.

Outboard thermostat
Works fine. A little pricey but better to buy the best than risk a cheap failure and destroy your engine like i did once.
