Zero Breeze Mark 2 Power Extension Dock - Charge While It's Running!

Zero Breeze sent me the new Power Extension Dock to test out. I found it does exactly what it's supposed to do, allows you to put a charge on the battery(s) while running the Mark 2. Something you weren't able to do prior to this dock.

Now there's no fumbling with cables when you're near an external power source, your Mark 2 batteries can always stay connected to the air conditioner.

Here's an affiliate link to the 12V to 24V DC power converter I use in the video (20amp):

i have mark2, I think it is a wonderful machine, It runs great and is performing nicely.

This is great. I have the ecoflow, and when it's connected to it's own battery, and then connect it to the power source, the wattage goes to 700+ draw. I keep liking my zero breeze more and more. I didn't know they had made all these cool accessories for it. :)

This was the exact information I was looking for! Thank you!

Man I have learned so incredibly much from your vids, even the fine details. The videos themselves are hugely helpful, but your interaction and responses through the comments are a goldmine. Thanks a ton. You live convinced me to purchase one, as well as at least one batter because I have a jackery 1500w, and can get at least two nights out of the mark 2 without needing a recharge of any kind until then. Got any suggestions on a good 12v to 24v 20amp DC converter for the jackery to the mark 2? Or does ZB sell them?

Great intro!! 🤣...thanks for making these detailed videos....definitely answer many faqs

I have the Mark 1 which takes 6hrs for the compressor come back on after you turn it off, so once you turn it off you are done until the next night or session. This means I had to come up with a way to never let the power to the zero breeze mark 1 run out which is not too complicated for DC power, here are the steps. 1) have a adjustable voltage that will go 1 or 2 volts higher than the device, in this case it would need to go to 25 volts. 2) splice the wires in the harness in parallel. So if you want the secondary source to feed the zero breeze as the primary, jump the voltage from 24v to 25v. If you want a 50 / 50 distro then make the secondary source voltage at 24 volt ( this could be 2 car batteries in series). If you wanted to you could also just run two of these zero breeze adapters in parallel so that you could go off your car and not risk any hot wires in the car, worst case is that your car fuse may trip if you don't plug into different fuses. You can also use this concept to power from solar, but make sure you regulate the panels to be in spec, the most important part is that the voltage will never go 1 or 2 volts over what is drawing the power. You can buy these device from amazon, the best devices are called a boost and buck DC converter which can boost a DC up to a voltage, or bring down the voltage to a certain voltage.

glad I found this video. I have a zero breeze, the two batteries, power extension cord and the Jackery 1000! I plan to connect the two 100 w panels to the yeti to charge it up while running. a question: is it more efficient to connect the power extension through the DC connector (cigarette adapter) OR through the AC plug into the Jackery? Thanks

Excellent video and I understand if I buy the battery I need a 24volt converter and that’s where the problem lies. I’m definitely not hardware savvy so not sure of all the extra components I need to convert and I currently only have a Jackery 300 with 1 100w solar panel.

Got mine as well. I believe in two battery scenario both battery have to be turned on to provide the 5A each to the aircon, otherwise one battery will stay full while the other one drains (even with Aux power plugged in).
Correct me if I’m wrong.

[codaxinc]

I have the same set up but . When I CONECT the battery from step up 12 to 24v . Won’t do anything . But when I CONECT ( step up inverter ) directly to Mark2 it will power it and running .Any advice ?

I’m looking to use a zero breeze mark 2 to cool my Honda Element to do some micro camping. Just to be comfortable through the night, I’d like to be able to run my zero breeze through the night on a battery “generator” I’m leaning towards the eco flo delta 1260wh, simply because it seems to charge the fastest. Also I plan to put 2-100 watt panels on the roof rack. Would love some feedback ? I appreciate your videos, they’ve helped a lot grasp the concept.

[stephenpiper]

I really enjoyed both of the Zero Breeze videos you have done. Have you or would you test the Ecoflow Wave?

[ryap]

Thumbs Up! This is a great demonstration that helps me understand. I have the ZB A/C unit & 2 ZB Mark 2 Batteries. ZB now sells it's own 100W Solar panels. Just think'n, how many of those 100W solar panels would be needed to power up the ZB A/C unit while charging both batteries using the Power Extension Dock?

[yotagang]

Question, so im planning on buying the mark2 without the battery, can i just connect it to ac power in my powerbank? cus i see u plugging into the ciggarette lighter in the power bank, is it better to charge off of the cigarette lighter? thanks

[manuelcorrea]

I'm not sure if you mentioned if you can power the AC with just the two batteries . I was out camping and noticed the AC only used 1 battery then shut off . What am I missing ?

[RafaelGonzalez-gdsr]

Be nice if you may can do the night test whit the new converter from the zero mark 2 thanks

[stevemontana]

So I just ordered the power dock with the Zero Breeze and one battery. If I understand you correctly then you can't have the battery just being charged on it's own and have the power brick run the AC separately, you have to have it run through the battery? So in other words if I wake up in the morning and the battery is dead I would either have the choice of charging the battery and have no AC or plug the power brick into the AC to run it and I wouldn't be able to charge the battery unless I had a separate power brick right? Thanks

Thank you for adding those diagrams in as well! I started to lose you halfway. 😅 I’m trying to solve getting A/C into my campervan whose electrical system can’t handle even the most efficient rooftop unit that would replace my MaxxAir fan.

Going to check out your other videos to see if I can find the right solution.

Basically I have 320W of solar on my roof with 200Ah via 2 AGM batteries running through a 1000W inverter. My Jackery can’t output the amperage needed to charge the Mark 2 battery and I’ve been looking to invest in a GoalZero w/external panels.

So as it stands, the Mark 2 cannot run directly off an external power source (it can only get its battery charged?), but with their Power Extension dock, it can charge its battery WHILE running, is what I gathered?

And if I get the Goal Zero and TWO Mark 2 batteries, I can both charge the 2 batteries, and run the unit at the same time?

The gray thing is an AC adapter to charge the Mark 2 battery into the wall (correct me if I’m wrong), but also without the dock, you cannot run the unit at the same time? I don’t foresee myself running it off AC, so I would only need the 12V - 24V Power Extension Dock?

Apologies for all the questions and no worries if you can’t answer 😅 I’ve just been wracking my brain over this one. I did leave them a voicemail but not sure on what their response time is, and I really need to get my van cooled! Thanks!!

[factsovafeelings]

So can it be used just to charge both batteries without running the unit??

I'm a truck driver so when I driving I want to charge both batteries at the same time when I'm not using the unit.

[billsmith]

Any chance you can do a test to see how much wattage draw there is from your 12v 25A aviation plug vs the AC/DC power cord especially for us Bluetti AC2000 users. Trying to see if it's worth building the converter. Think it would be any different from your previous test video?
