What’s the problem with the included power supply? I’ve been considering getting one of these, and was just going to get the kit with the power supply.
This one on Banggood seems to do 2A, but I have no experience with it.
I don’t know. I have had no problems with the power supplies that came with my Lii 500’s.
They have been used a lot also. a whole lot… the original power supplies are still working just fine at this point also. 
Maybe ‘ImA4Wheelr’ will see this and tell us what problems “he” has found with the power supplies that come with the Lii 500. I’d like to know also. :+1: . :question:
Welcome to BLF joxidfa!!
I don't know if there is a systematic problem with them or if the issue is with my specific sample. I suspect that the power supply that I received with my first unit killed my first 2 Lii500's because they initially worked, then started acting funny, and then died. When I tried to use that same power supply on another charger (not a Lii500), it began acting in an erratic manner too (restarting the charge cycles and responding to button presses in unexpected ways). It was at that point that I realized the power supply may have been the root cause of my Lii500 failures. I don't know this for sure, but I suspect it enough to not trust it. Since power supplies are plentiful and cheap, it went to the recycle center.

Yeah, that does sound like you had a bad power supply. :+1:
So far the ones with my Lii 500’s have held up well through much use, but I have a backup LiteOn 12V 5.5A power supply ready for action should I ever need it. 
I use a homemade 5 amp power supply I put together a couple of years ago with a module I bought off eBay similar to this. It has a very stable regulated output. Never had a problem powering any of my chargers.
I have 3 Lii-500”s, 2 that came with the power supply that have had quite a bit of use the past 12 months of ownership & have performed faultlessly & the 3rd a charger I bought about 3-4 months ago without a power supply for $12 iirc.
I bought a cheap Chinese 12v 2A supply (& I mean cheap, iirc it was $3) for this 3rd charger & this also works perfectly :+1:
I have many Li-ion chargers (Opus, Nitecore, Xtar etc), 12 plus, & the Li-500”s are by far my most used & most liked chargers.
To me this looks like a wonderful idea…… :+1:
I was/am still thinking about doing it. I was reading about it some on an OPUS charger thread , and some questions came to mind. How is the best way to know it is a good one and not some cheap piece of junk???
Some “name brands” were mentioned below, I am assuming they are good. What are some others??

In the states, the Dell Optiplex FX160 Power Supply are often available unused for under $5. One can power 2 Lii500's simultaneously. Output is very clean based on my crude oscilloscope reading skills. Here is a link to a vendor I have purchased them from in the past. You just need to wire a 5.5x2.1 jack to them. You could swipe the jacks from an old wall wart power supply like the one that comes with the Lii-500. Just make sure to wire positive to the center terminal.
Goo info!! Thank you. … :+1:
I bought the cheapest no name brand I could find. I actually bought a spare as well. I burned both of them in by drawing it’s full capacity for hours, and even shorted the outputs several times to make sure they wouldn’t fail under extreme conditions. They both passed. I keep the spare around just in case the one I’ve been using for 2 years fails. So far it’s been bullet proof.
Here it is drawing almost 6 amps. It got pretty hot after about 10 minutes, but it handled it. It shut down when I got to 6.2 amps but it recoverd no problem once I reduced the current draw.
Well there you go then. That pretty well sums that up and answers my question too. :+1:
Thank you my friend.

EDIT: Nice looking set up you have there. :+1:
The top unit is a load tester I built a while back out of boredom.

Nice……… :+1:
Thanks my friend. It’s a bit Rube Goldbergish, but it works as intended.
Sure thing. And as far as I am concerned…. “works as intended” is what counts. :+1:
I ordered from your link. It’s purpose will be to power my security cameras. The 5 only draw 3 amps total. This should be fine.
I haven’t checked for ripple because I don’t own a scope, but I will say it’s been dead reliable with all my chargers for the past couple of years. Maybe I should invest in a scope. Any recommendations for less than a few hundred dollars?
This Rigol is highly rated. It can be cracked to 100 Mhz.
It’s still a lot of money, but I don’t know of anything less expensive that’s worth buying.
got a dead xbox 360?
the power supplies range from 10 to 18a and are easy to use.tie red and blue togther.all the blacks for - and all the yellows for +.
My first order on Ali, used link in first post which says its the liitokala Official Store, costs were $14, $16, $17 shipped depending on charger and car adapter.
