These are my personal notes. Apply at your own risk.
Note: Although the found label on the wall wart says 13V, at least one motor and the battery are all 12V which but one motor might be 12.5VDC. To be safe, it is probably better to under-voltage a device than overvoltage.
We went to sell the Lobster Pickleball Machine and could not find the power supply.
The information is a bit tough to find online. Even the machine itself does not list the power specifications which is unusual. After a lot of searching, I finally found a video showing the specs of the standard charger. As you can see, it says it is 13VDC or 13 volts DV and 1 Amp.

As far as I can guess, the premium charger is likely 13VDC 3A, allowing the device to charger quite a bit faster. Also, the premium charger has trickle charge capabilities, which tend to be better for the health of battery and can stay plugged in all the time. The connector on these chargers seems to often feature an XLR-style male connector. One reviewer on Amazon said he had luck with a $30 similar option, the "SONEIL CHARGER 1206SX2 100-240VAC IN 12V 3A OUT 3 PIN XLR CONNECTOR POWER SUPPLY." Not sure you should under-voltage the machine though if it requires 13VDC. Specifications:
Input: 100-240 VAC ~1.5A (MAX) 50/60Hz
The battery inside the Lobster machines is a fairly standard rechargeable battery. Lobster Sports sells it for $85 and lists it as compatible with Elite One, Elite Two, Elite Three, Elite Four, Elite Five, Elite Five LE, The Pickle Two, and The Pickle Champion. These look similar to Power Sonic batteries which end up being a bit cheaper with similar specs.
Inside our machine, The Pickle, I found this battery, a Zeus 12v 9Ah. Lobster Sports sells this style battery for: Elite Freedom, Elite Liberty and The Pickle.
