Truetone One Spot could work with 1.7A
Kellerblues the One Spot may be shy of the 24 watts the KPP is rated for (at the Truetone’s 9v that’s a bit under 2700mA).
Some have reported that KPP’s work with less than 24 watts, and others have said they endlessly power cycle when under powered.
The Truetone seems to be suited for most standard guitar pedals that aren’t power hungry like our KPP’s or a Quad Cortex (will I be hit by Internet lightning for saying that product name here? 
).
Let us know if the Harley Benton works! Sweetwater has a similar one that is a little pricey but I will grab if it works...gotta have a spare.
I contacted Kemper support so see if they sell spares but have not heard back yet.
I've called Kemper (but had to leave a message), scheduled an in-person appointment at their showroom in Chicago (but never heard anything back to confirm), I've emailed (TWICE), and asked about getting a backup Player power supply multiple times in the comment sections of Kemper's Instagram posts about the Player. Crickets. When I had an issue with my Stage a couple of years ago, Kemper's customer support was SUPER fast, friendly, and totally helpful. Now..... Ugh.

Dave,
We were closed for the Easter holiday and I believe you received a call back already. We have replacement Player Power Supplies on order and should be getting them in the next 2 weeks. As for your appointment, you were scheduled for an appointment and didn't show up. We were there! Perhaps your email confirmation is in your spam folder? Never the less, we will have new power supplies soon, and there are many other options posted on these forums for power solutions, from the CIOKS, Palmer, etc.
This adapter is exactly the same as the original :
Theres tons of them out there but I doubt I would call any of them high quality.
This one looks like it might be ok:
This adapter is exactly the same as the original :
HN Power HNP24-090L6 ( Google Search )
but it´s 24V

Doesn't work! inside positive, outside negative
I can confirm:
Works really well with the player.
I have one and its tested.
One small thing is the plug is a 90 degree one which touches the corner of the player, i prefer the original adapter with astraight plug.
I finally got this:
Works fine (with Mac and USB!! (Ground)…)
While I was out and about, using only headphones, I noticed that the player was humming a lot and I read here in the forum that it was because there was no ground. Kemper was being stingy not to solve this problem with a suitable power supply. So I ordered this for when I was out and about:
We will see …
I use this:
And this:
In combination with a current doubler cable.
I even power three analog pedals at the same time. 
Don't do what I did and have your Player stolen out of your car. They left the power supply, though and I bought another Player....so I have an expensive spare
The TrueTone 1-Spot works well. No noise at all.
TrueTone has only 1.700mA, Roland only 2.000mA, recommended are 2.500mA
Both don't have ground.
Try the player with headphones only, it's a mess how it crackles and hisses without ground
