I was trying to pull data from a failing SSD with a 2-bay hard drive cloning dock, and the power went out. I do not live in a stormy area, a city serviced by PG&E (where power cuts happen due to aging transformer failure 3-5x a year). Next time I attempt this, I will be using a laptop and a USB enclosure, so the laptop battery can kick in during a power cut.
Now I have multiple planned cloning operations involving 3.5” HDDs in the future, which could take days due to the drives age or size.
While I could buy a small Jackery power bank and plug my 12v power supply into it, I am on a shoestring budget so I am looking for a Lithium Ion battery pack able to supply a regulated 12V and 2A constant amperage for 3 hours. I have a Talentcell 100Wh battery pack (link in the URL field of this post), and its voltage output is variable based on it’s state of charge. If there is a lithium battery pack on the market able to supply -tightly regulated- and -stable- 12V, I have not found it.
Another solution I identified is to plug in a DIY connector with a in-line output voltage regulator module. Could somebody recommend a 3A rated (1 Amp overhead for longevity) output voltage regulator module which can take the 9-13V from my Talentcell and output a stable, regulated 12V +/- .1V and 2A? I could use this homemade connector between it and the 2-bay hard drive cloning dock.
Either one, buying a lithium-based battery pack with tightly regulated and stable 12V output or the right output voltage regulator module would be a solution to my problem.
