Description
Optimal Use / Precautions:1. Always make sure that the total rated power of the connected devices is 1000W.
2. Always tighten the Positive (+) and Negative (-) terminals when the inverter is in use otherwise a loose connection can overheat due to poor contact.
3. Avoid placing the inverter in a location that receives prolonged direct sunlight or near to heat sensitive materials as the inverter can become warm during use.
4. Converts DC power in your 12V batteries in your car, truck, boat or any other DC power sources into the AC power that home appliances, electronics and tools need.
5. If the rated input of any connected AC devices exceed 150W use the included battery clamps to directly connect to your vehicles battery as most vehicles 12V ports are rated and fused for 150W.

6. Step Up Voltage Converter 5V to 9V/12V USB to 2.1mm DC Booster Cable 1.2M (12V)
Feature
5V to 12VCable Length: ~1.2m / ~47"
Description
This cable is kinda fascinating - it has an integrated boost converter, so you can plug it into any USB port (from a computer, battery pack, etc) and it will give you a higher DC voltage! It's a handy way to power 12V powered devices with a center-positive 2.1mm DC barrel jack from a USB port.These are rated at 500mA output, but you can go a little higher, we pulled 700mA and we got a little voltage droop but it worked fine. Probably best not to draw 700mA continuously though!
Here's our measurements for various current draws when we set our bench supply to provide a steady 5V voltage
50mA (12.4V output), 150mA, 83% efficiency
100ma (12.4V), 290mA in, 86% efficiency
200ma (12.3V): 570mA in, 86% efficiency
300ma (12.2V): 870mA in, 84% efficiency
500ma (12.1V): 1500mA in, 81% efficiency
700ma (11.4V): 2140mA in, 75% efficiency
So, overall there's a 85% efficiency at low current draw that drops do about 80% at high current use. There's also a 3 mA quiescent current. Note that often times the USB port voltage can droop too, and in addition you may have power losses with any thin or low quality cables with high resistivity!
