HD Native Power Supply
It's been asked many times but I have never seen it actually answered. Is there a way to purchase just the power adapter for the HD Native TB? I realize it is bus powered and it works fine that way. The reason I want one is because I noticed that when I have the HDN TB connected, the laptop battery drains aound 3 times (maybe even more) faster than when it isn't connected. So, I figure if I have the power adapter, that will save me a lot of power cycles on the battery of my new MacBook Pro. Another plus is that I won't have to disconnect it when I'm not recording. Every time I disconnect the HDN the MacBook restarts and there is a panic report when I reboot. The main concern is the battery usage. Thanks in advance

Re: HD Native Power Supply
Just beware of grounding issues.
I had one HDN|thunderbolt bricked because of some strange issue with electricity. The bricked box went to Avid and I got a replacement, but I did not get (and did not further ask, because I was okay with the replacement unit) any explanation what went wrong. Just my educated guess that whenever you have too many interconnected cables and therefore too many possible ground loops, things may happen.

Re: HD Native Power Supply
Wow, I wonder how common that issue is. Thanks for the heads up. How long ago did that happen? I wonder if there have been any revisions to the HDN or the power supply since then? I guess I'd be willing to take the risk. I'm going to try and contact Avid sales tomorrow and find out if they even sell a replacement power supplies. Maybe they would know who to talk to about any electrical issues

Re: HD Native Power Supply
Did Avid ever actually sell a rebadged power supply, all occurrences I've seen folks just grabbed a third party 1A/12VDC supply. Make sure you are using a center positive barrel connector on the power supply brick.
Would have to be a pretty horribly bad design for the power brick and/or Thunderbolt box for this to blow up the box... not saying that can't happen. |

It must have been 2014-2015 (ish)

Re: HD Native Power Supply
I'm confused. If you have an available outlet to plug the TB box into, why not simply plug the laptop in and not run on battery?

Darryl, I looked at a picture of the power supply on the Sweetwater site and it looks like it is rated for 1.5 amps. I know it says 1 amp on the back of the HDN, but it probably wouldn't hurt to go with a 1.5 amp. So I'll be on the lookout for a 12v 1.5 amp center positive power supply. I didn't get a chance to contact Avid, but I'll try and remember post what I find out |

I remember that was the advice Apple gave back when I had an iBook. Now the suggestion is to leave it plugged in unless you need to be mobile. Occasionally disconnecting and running on battery power is advisable, but there’s no need to do the whole full charge, full drain, full charge routine like in the past. Also, there’s all sorts of smarts on modern laptops. Like iPhones, they do trickle charges etc. to maintain battery health.

Re: HD Native Power Supply
Not only is that outdated advice, that cycling will reduce battery life.

Re: HD Native Power Supply
Your saying cycling the battery is outdated advice? All of the info I've seen online says that's the way to do it for lithium ion batteries
