Similar to my "is the power tank worth it?" post, I'm debating the charge tank. I have the impression that it's pretty rare for public J1772 chargers in the US to go much above 6kW. What are your real-world experiences like, particularly when touring?

You have 3 options:

- Seek out exceedingly rare 19.2kW J1772 stations. Currently you are most likely to find these at special Rivian-built charge points
- Seek out Tesla Destination EVSEs known to output 12+kW using things like Plugshare or Tesla's maps and bring a TeslaTap Mini
- Make the intelligent decision and buy this from Scott. He's a good boy.

It varies like crazy. I used a 40-amp (9,600W) J-Plug here today. I charged my 2017 Zero SR at 7.888 KW today, as it showed on the APP from the charge station. And that is pretty good since my chargers only add up to 7.9 KW.


I have seen J-plugs as low as 3.3 KW and as high as 16.8 KW. Most are around 7.7 KW.


The Tesla Destination chargers are usually higher power, (12, 14 & 18 KW are common), but I often have trouble with the 14KW shutting off after five minutes of charging with a Tesla Tap. I have no idea why.


I never have any problems with the 12KW Tesla Destination charge stations, so I like to use those when possible. That is the same one I have at each of my houses. The higher-power ones are older. Probably from the time when on-the-road charging was not as common as today, especially for Tesla.


I decided I did NOT want the extra charger on my 2023 Zero DSR/X. I prefer the extra storage space and in most cases, the 6.6 KW charge is about right for my lunch breaks or whatever.


When I got back to my Zero SR today, I was at 99% SOC.  That is close enough to perfect for me (the ~8KW charge in this case). After 95% SOC, I am only using the bike's OBC (no Canbus connection) so the last five % is very slow. That gives me the time to put things away and get ready to leave.

I see many 7.2  plus around here all the time.  That would be 240 volt 30 amp, a pretty standard configuration.

Pretty much any 240 volt fixture /plug around is fused /breakered generally at a minimum of 30 amps.  Unless they are going on the cheap, and converting an old 115 circuit to 240 volt for the charger (which would probably have a max of 12 ga wire  rated at 20 amp) you should see 7.2 or more easily

If you are getting iterations that are inbetween 10 A steps like that, mostlikely that is the bike throttling it down for some reason.

Take into consideration the fact that if you have the new BCB battery the charging power is cut back pretty severely. If you are charging from 50% to 100%, you are not going to improve the charge time much even with the full 12K available from the charge station. If you are running the bike down to 20%, then you will see higher charge rates and might be worth it. There are some Rivian chargers near me that are 9K, and a couple of 19K blink stations. The Tesla destination chargers are often at hotels and might be restricted but some are open to the public so I do use my Tesla tap sometimes. The 10% Cypher upgrade might be worthwhile.

I have added the rapid charger to my DSR/X  and am happy with it. There are a lot of 48 amp level 2 chargers as well as 80 amp where I ride. Tesla has added a lot of there universal wall chargers in the last 12 months. These are public and the price is all over the place because it’s set by the site host. Must use the Tesla app to start the charge.I have also noticed the Ford dealerships around here are building public access charging with DC but more importantly 80 amp level 2 for me. Make sure you purchase an 80 NACS to J1772. I had a problem with the charging being reduced due to handle overheating with the 48 amp unit I had. Purchased the A2Z 80 amp adapter and problem solved.
