The charging power is designed to go to the batteries first. The batteries then feed the power to the Mark 2 AC.
The max charging current accepted by each Mark 2 Battery is about 5.5A, and the max current consumed by the Mark 2 AC is about 10A. If two batteries are connected powering the Mark 2 AC whilst charging by the power adapter, the Mark 2 AC will always have sufficient power, and the batteries will be fully charged.
However, if only one battery is connected powering the Mark 2 AC whilst charging by the power adapter, the battery will drain out.
If the battery is fully charged, it can last 5 hours powering the Mark 2 AC without charging, with the extension dock charging by the power adapter, it can last around 10 hours.
Use 12V to 24V Converter and Power Extension Dock together. The 12v cigarette socket can not charge through the expansion dock for both batteries. Damage may result from incorrect usage.
Accessories of Mark 2 do not support the 30-day return policy.

Alltho it does extend the run time of the Zero breeze by using more than one battery pack at a time, it does not seem to recharge the batteries at a fast enough rate while the Zero Breeze is running! This means that the Zero breeze will eventually run the batteries down even when the charger is plugged in!
I am using the Zero Breeze in my semi truck with a robust electrical system that can fully support the Zero Breeze power needs and I had to make a fully custom wire harness to bypass this box.
i will only reccomend the power extension for light car applications without upgraded electrical systems only and NOT for vehicles with larger electrical systems!
Truckers need an upgraded version of the power extension that can charge both batteries in parallel faster than the Zero Breeze can deplete the batteries.
I made a Youtube / Rumble series, please watch videos for more explination. I truly hope this helps future products.
I truly do enjoy the Zero Breeze as its the right size and efficency for my needs. Feel free to contact me via email for advice on how to improve the products as much as you like!
It’s worth it for a semi truck
Using the power extension dock I can achieve longer run times by connecting my 100 AH battery, portable power station and ZB battery all together achieving 14+ hours of run time.
I use it every night. Works great.
My only gripe are small things such as the battery activation buttons. I use two batteries paired to power the machine. You have to hold the button for 2 seconds then listen for a ‘beep’.
I wish it was just an on/off switch.
Also wish I could control the temperature of the unit. I’m trying to conserve as much energy as I can and it seems odd it just runs all-or-nothing. I sleep great with 55 degree air blowing on me.. But I’m happy if I could just set it to 74. The machine wouldn’t have to run as much.
The remote could also be better. You have to get with in only a couple feet for it to communicate.. I might as well just step a foot closer and just press the button on the machine..
