Good product

Good seller

Works great

I own a 22 foot c dory cabin and needed to cool down at night so I can sleep, I had to turn it off around 4 in the mornings it was to cold. During the day it can not cool the cabin, but it helps with the heat.


I Can use the zero breeze mark 2 without having to switch batteries. Game changer for sure 😀

Excellent service

It's just starting to warm up here in the West, so I can only say that I've single cycled them and they took a full recharge. The first 30 days of summer will tell the story. As for Tredless, very good service and their communication through the process was excellent.

Great Buy

I love my purchase for half the price.

Best portable AC on the mark

Wonderful little AC~ I would call it the Swiss Army Knife of Air conditioners ; ) it’s little but meets my needs, just being a realist ~ will be used this summer on my boat and in my camper~! Love the fact that you can use it with plugging in~ the battery should just enough to carry me through those hot summer afternoons! “As to tredless” so glad I found them…. A+ customer service!! Thanks!

Tredless Has Your Back

I’m on the road and I needed a replacement battery for my Zero Breeze A/C. Mike said give me an address and I’ll send it today. Well, I had to check with my buddy to use his address, sent Tredless the info next day and I had my new battery and back on the road within a week. The Tredless company and Zero Breeze are a good combo. The A/C is excellent in my 2500 ProMaster!

Like new! Wonderful customer service and fast shipping!

If it wasn't for some extremely faint markings on the hooks connecting the battery to the ac I would have thought it was a brand new battery. Works and looks like new! Great holiday sale price allowed us to make our unit more flexible on how we use it. Forgot to activate a coupon during purchase and within a couple of hours (on a Sunday night to boot) Mike had already applied and sent the refund for the coupon price. Fantastic customer service much quicker than expected. Thank you Mike and Tredless!


So I’m really impressed with the quality of the battery and will try and buy more stuff from here

Zero Breeze Mark 2 Air Conditioner

My a/c arrived within a week of ordering and the battery a couple of days later. Both looked to be brand new and worked perfectly. I saved more than $600 v. buying “new”. I also bought the three-year warranty in case the parts were really used. I would happily it from Tredless again.

Awesome Product, Great Price

Been saving to buy zero breeze for over two years. It’s the final piece for my van conversion. Somehow I got really lucky and found one with the scratch on it for half off on this website. I can barely even see the scratch and it runs great. I had a slight problem with the shipping, which was fixed promptly with very polite and thorough customer service. Very good experience. Would shop here again.

We were very pleased with the prompt replies to our emails and the generous compensation when our order was delayed.
When our Open box Zero Breeze Mark 2 portable air conditioner arrived we were very happy with it and suprised at how such a small unit could work so well!
We are planning on using it in our small pop up tent trailer and we are confident that it will work well for us!!

Outstanding customer service

From the initial order confirmation to delivery, Mike at Tredless assisted me with all my questions and delivery concerns. I couldn’t be happier. I look forward to doing business with Tredless in the future. Thanks again!

I am very pleased with the customer service and the product!

Don't let the Zero Breeze poor customer service reviews you read online keep you from buying this product. I was happy to buy it through Tredless because their customer service & communication is great & with the open box deal, more affordable for me. With my solar panels & Jackery 1000, it works great. I even cut 2 holes in the side of my camper van for the fresh air intake & the hot air exhaust. Now I can finally quit paying 30 to 35 dollars a night to camp with shore power. It really IS a game changer.

Good for what it supposed to do

Had this unit turned on to rocket mode and the temp coming out was 53 degrees, which was plenty cold. As a spot cooler, it kept ME cool and the humidity at bay !

Double Delight

The product was packed well and arrived early thanks to Tredless. The A/C unit performed as well as I hoped. I set it up in my van with intake and exhaust tubes ventilation out the window. I watched the temperature reading drop about 20 degrees in about 10 minutes. I went back in the van after 1 hr. and found the temperature had dropped 5 degrees from outside and the condensation drainage was exactly 1 cup. I’m looking forward to enjoying comfortable conditions traveling with my Zero Breeze!

Bargain of the season

Unit was scuffed as expected with no other serious issues of note. Also, received 2 batteries. Packing was perfect. Remember AC units need to operate at warmer temperatures when yours arrives and you want to test. Mine is functioning normally in a warm house environment, dare I say, as expected. Buttons and indicators are good. Charged both batteries to max and they are holding. Also, ran it with the AC adapter. Haven't had a chance to test it with the lithium setup in the camper yet. It's cold in Michigan right now. We are going to cool a heavily customized, 10' x 7' A-liner Scout Lite and roughly 450 cu. ft. while boondocking. Should be a Breeze.


Everything worked great even though if was an open box purchase! Happy I was able to get this with the extended warranty. I would buy from here again.

Zero breeze batt.

Great price and as new. Recommend Tredless. No issues.

. Open box

Item is good packing. I tested it's good working. I just wait for summer.

First impression

Elite generator seems very well built. Has many receptacles and even a 220v
one. Has 3 ways to charge, electric, solar, and wind turbine. Came with adjustable handle. Wish there was a MC4 to Anderson port type connector available. Sales staff very helpful all along. Joe Bock

Great customer service

I was initially concerned when the first unit I ordered did not work. When I sent an email with details they immediately responded with options to return for refund or they would send a replacement. I had them send a replacement and it works great. I would not hesitate to order something else from Tredless.

Great Buy

I was hesitant, at first about purchasing from Tred Less because it was new to me. But I am so HAPPY I did. I spoke with Mike and he answered all my questions, put me at ease. The scratched item I ordered looks pristine. Truly a great shopping experience
