4. BATTERY EDUCATION 101
Device Runtime | AC vs. DC Power
In general, it is normal for power losses to occur when energy is transferred
from the battery to the ports that power your devices.
The AC port requires an inverter, which transforms power from DC to
AC. This process creates heat and consumes about 15% of the power it
transforms. DC ports are more efficient and only consume 8% of the power
that is transformed.
Your device will always last longer when plugged into DC ports if that option
is available. For example, a CPAP machine will last almost an extra night
when using a DC CPAP converter compared to the standard AC plug.
Heat is the Enemy
If the Arc, or any power station, is left in the heat it will impact its health,
capacity and longevity. Keep out of hot cars and direct sunlight on warm
days. Heat is the #1 reason batteries degrade prematurely.
Determine The Power Consumption of Your Device
Device with no battery: locate Watts (W) on the product.
If Watts are not available: multiply the Voltage (V) x Amps (A) to
arrive at Watts. Eg. 120V x 0.6A = 72W
Device with a battery: locate Watt Hours (Wh).
Or multiply the Voltage (V) x Amp Hours (Ah) to arrive at Watt
Hours (Wh). Eg. 12V x 1.0Ah = 12Wh (Note: 1.0Ah = 1,000mAh)
