The 12v Power Packs come standard with USB Ports and DC Receptacle (Car Cig Plug) and can power a wide range of 12v products.
The question to ask yourself is...
Our standard power pack specs are as follow:
Voltage x Battery Amp Hour Capacity = Watt Hour.
12 Volt, 20 Amp hour = 240 Watt Hour
12 Volt, 40 Amp hour = 480 Watt Hour
12 Volt, 110 Amp hour = 1320 Watt Hour
Based on the Battery Rating and the item you are wanting to power, It is a simple calculation to determine how long it will power that item
Lets say you want to power a LED light strip with our 12v 20ah Power Pack and the LED's are rated at 26 Watts. You take the Power Pack Watt Hour Rating / the LED's Watt draw rating:
240 Watt Hours / 26 Watts = 9.2 Hours of use

Our JUICE Pure Sine Wave Power Inverters provide reliable transformation of DC power from a battery, such as the one in a car or RV or using one of our Juice Power Packs, into AC power that can then be used to run lights, computers, televisions, satellite receivers, stereos, and a broad range of appliances.
The standard models comes with a 12VDC Receptacle, Dual 5VDC 2amp USB Plugs, and Voltage/Amp Output/Watt Output Readout display.
They also have Dual Battery Terminal Post. This gives a user the ability attach a battery or Juice Power Packs directly to the Inverter Pack, as well as chain multiple batteries of Power Packs together to increase battery capacity for longer runtimes.
To select the right inverter first determine what devices you would need to run, then select the appropriate inverter that can carry the combined wattage requirements of those devices.
**** All Wattage examples are based on an average. Review your own devises specifications to determine more accurate Total Wattage Draw and Runtimes.
To power a typical Tailgaing setup, you would have a 50" LED TV (60 Watt power draw), satellite receiver (20w), LED String of lights (26w), and a stereo (80w) = 186 Total Watts. Based on 186 Total Watts, our JUICE 300w or 600w Inverter Packs would handle the load, but the 300w only has one 120v outlet. It is not recommended to power more than 2 devices per outlet.
Still using the 186 Total Watts to power our tailgating setup...
Which Battery Power Pack Should You Use?
Battery Watt Hour / Total Watts = Hours of Use
12 Volt, 20 Amp hour = 240 Watt Hour / 186w = 1.2hrs
12 Volt, 40 Amp hour = 480 Watt Hour / 186w = 2.5hrs
12 Volt, 110 Amp hour = 1320 Watt / 186w = 7.1hrs
In this example, we would recommend the
JUICE 600w Inverter Pack
12v 110ah Power Pack
This combination will power our Tailgate for approximately 7 hours
