Comment on How to auto remount external HDD after power loss to laptop server?
Lenna@piefed.ca 4 weeks agoDo you have a USB power bank you can recommend? My external HDD requires a wall plug and I’ve never seen a USB power bank where I could plug my HDD into it.
There are DC UPSes that can supply 12V and are typically used to keep wireless routers and security cameras running for a few hours during power failures. They plug into the mains and are about the size of a 3.5" HDD.
Most USB power banks power cycle when the switch between charging/supplying/pass through mode, so if you use them for computer equipment they will lose power for a few seconds when the mains comes on or off.
Edit: DC UPSes are also much cheaper than standard ones.
Hey there! A moderator just restored my post and you probably never got the notification for my previous comment. I was just wondering if this is the UPS you had in mind.
Hi! That looks way more expensive though it might work for you. This is what I had in mind: www.amazon.ca/…/B0F66B34WN
Unfortunately, my HDD doesn’t support those ports so I guess I’ll just suck it up and spend the extra $20. Thanks for the help! :)
You have a 3.5” based HDD (aka desktop drive). many people use 2.5” drives (laptop drives) since they get power from the PC with just usb
So that means it’s not possible for me to power my 3.5” HDD with just USB, right?
100% correct. You need a wall adapter. As many have said we all recommend a UPS (Uninterruptible Power Supply) or battery backup for your stack.
You can get the cheapest one if it’s just short term outage or brown outs (grid low volting).
Based on your wattage the capacity of the UPS will dictate how long it’ll last during an outage.
I was thinking of 2.5” inch USB drives powered by USB cables….
For 220v ones get a proper ups power strip. They are cheap about 50-60 bucks
