Is it possible to power a 7U 104hp case from a DC supply, e.g. battery or PV solar panel(s) ?
That’s a really neat solution. Sadly it’s showing as currently unavailable.
What size rack are you using it with, and how long do you get ?
The input voltage for the case power supply is from 15-18V so you could use another battery pack with a similar voltage range. Just pay attention to the connector polarity indicated on the back of the case. If you find something that works, post about it here!
I was reading in the comments on one of Anne Annie’s videos that she used something from Goal Zero to power her system in her “Modular Road Trip”.
I’m not sure which model, but their base unit seems pretty reasonable: https://www.goalzero.com/shop/power-stations/goal-zero-yeti-150-portable-power-station/
Thanks for the info.
The GoalZero range look nice, though I’m in the UK, so I’ll look out for something similar, but suitable for charging from 220/240V.
I really like Anne Annies’s road trip videos. Indeed they’ve contributed towards inspiring me to want to play in a natural setting.
Yeah me too! That’s exactly why I was looking into portable solutions. Love to hear from people’s experiences on this.
Also, if you do some videos of your system in a natural setting be sure to share it with us!
Slightly off topic, but Ann Annie is a guy.
Oh really? You can understand why the name threw me off, right?
The Goal Zero Yeti 150 is Modified Sine Wave and not Pure Sine Wave output. Is that a concern or no?
album release page mentions “her”, the mystery lives on.
I just noticed on a Make Noise video out in a park they say they’re using this guy: https://www.amazon.com/100-Watt-Portable-Generator-40800mAh-Emergency/dp/B01M3S00H0
@ScottMFR, you’ve confused me. That Paxcess device outputs 12V, but kamil said that the 7U case needs to see 15-18V for it to derive the +/- 12V rails. So, is the Paxcess outputting a bit more than 12V, or is the 7U happy with a mere 12V ?
Oh you’re right. I hadn’t noticed that. I guess the Make Noise cases only use 12V.
The Paxcess also has regular 110V AC, so you can just plug in the power supply as you would to a normal outlet.
I am also looking for a portable solution for my Intellijel 7u 104hp case. Do you guys think any of these two would work?
I already got some portable speakers, just missing the power supply
My concern would be that it states a 65W max while the Meanwell gsm90 used by the 7U 104HP is 90W. I bought one of these usage monitors to test what the actual power consumption of my case is: https://www.amazon.ca/Kuman-Electricity-Monitor-Overload-Protection/dp/B07DPJ3RGB/ref=sr_1_4?ie=UTF8&qid=1546968034&sr=8-4&keywords=voltage+meter+lcd+display
I’m also planning to write an article for Ask.Audio next month on this topic as it seems like there’s a lot of people interested but not a lot of good information out there.
The TPS80 power supply in the 7U case can draw a maximum of ~80W, but that would be with it fully loaded, so you’d have to have some pretty power-hungry modules in there. It’s definitely a good idea to find out the peak power consumption of your system before trying another power solution.
Thanks. This would be awesome, please post link here when available.
I haven’t looked at the wattage in the ads for example. As many people I believe, I am completely illaterate in what concerns eletrical power so a good all-around article explaning what to look for in a battery for beginners would be truly awesome for a lot of people I’d say.
