The Simpler The Better

Diesel APU

(Diesel Generator)

Fuel Consumption & Emisson: Despite reducing idling, they burn diesel fuel, increasing operating costs and contributing to air pollution.
Maintenance Demands: These mechanical units require regular maintenance and are prone to wear and tear, potentially leading to breakdowns.
Noise disruption: Their operation can be noisy and cause vibrations, disrupting driver sleep during rest periods.
Cost: People spend 12k-15k for one unit, plus continuous fuel cost, maintenance cost and repair cost.

Electric APU

(AGM Battery)

Battery Weight: a Group 31 AGM battery weighs roughly 70 lbs, over 2 times over heavier than a lithium battery
Alternator Upgrade : Electric APU application which contains AGM batteries requires truck alternator to be upgraded to 300 amp or more. Wiring and cabling have to be updated as well.
Quick Degrade: Excessive deep discharges below 50% capacity and sustained high heat levels above 77°F can degrade AGM batteries prematurely
Life Span: 3-5 years

Electric APU

(Deep Cycle Lithium Battery)

Battery Weight: a Group 31 lithium battery weighs roughly 20-30 lbs, significantly lighter than AGM battery
Isolated Lithium Battery Bank: Because this lithium battery can't crank the truck, it has to be setup as an isolated battery bank to supply power for A/C. It needs a battery charger for charging purpose, however, the charging speed is high depended on the charger.
Alternator life: Due to additional lithium battery bank added to the alternator load, alternator is working more, and the alternator life will be shortened.

Electric APU

(Dual Purpose Starting + eAPU)

Battery Weight: a Group 31 lithium battery weighs roughly 30 lbs, significantly lighter than AGM battery.
Drop-In Solution: Direct replacement of your starting batteries, no additional battery box and cables needed.
Installation: Quick and Easy, same as your replacing your starting batteries.
Smart: This battery is designed for starting the truck and power all your household needs. It automatically shut off at 12%/25% (depends on the outside temperature)
All Season Operating Temperature: -40F-149F.
Simplest and Transparent APU: No more secrecy from the Diesel APU and most electric APUs, Polar Fox APU's standard package includes two components: BATTERY and A/C unit. The simplier and the better!!!
