Hello Everybody.
Recently I have been less focused on my electronics projects and working on my fundamental understanding of physics. However I have reached a point where I really do need a lab power supply to further my learning.
Unfortunately money is far from unlimited so cost is a factor. I looked up Lab power supplies on ebay and found this:
http://www.ebay.co.uk/itm/New-HQ-Va..._Measurement_Equipment_ET&hash=item5d398266ea
At first glance it looks like a really good deal however that is what all sellers want you to think. What do you think of this cheap lab power supply?
What are the limitation likely to be of a very cheap lab power supply compared to main brand one built to a much higher standard?
I am mostly likely to use it for low power experiments and am unlikely to use its full rating for anything but brief periods. I also wish to use it to charge Li-ion cells, one concern is that if it misbehaves and decides to put far more voltage or current through the cell than I have set it to. How likely is this to happen on a cheap Power supply? For those that don't know Li-ion's are safe within certain voltage limits but can explode if their voltage rises beyond a certain limit or if they overheat.
Thank you
