Look Bonkers, I understand your concern, and 10 years ago I would have thought the same thing that if something made sense that it should happen no matter what and it was someone's job to do that and everything that everyone thought made sense.
But that's just not how the world works. You mention Yamaha. If you put an aftermarket pipe on your bike, and shortly after your exhaust valves burn out, Yamaha will show you the fine print that an aftermarket pipe voids your warranty.
However, I'd say half of all sport bikes on the planet have an aftermarket pipe. Why? Because companies like Yoshimura, Two Brothers, Akrapovic, Vance & Hines, Leo Vince and many more are trusted by the public to make a good product that will not damage the bike. It is not Yamaha's job to test each exhaust system and give it a stamp of approval. If there is only one pipe maker on the planet, you might ask Yamaha to test it and promise you it won't void their warranty. What when there are 2 pipe makers? How about 100 pipe makers each year for each bike they have? Is it still Yamaha's job to test all these now?
So what happens in 5 or 10 years when there are 100 aftermarket chargers on the market that work with Zero's? All different power levels. All different sizes. All different adapters. I can't wait for the handlebar insert and bar end charger. I'm gonna get two of them, one for each side. 500 watts each using micro silicon carbide mosfets and super tiny. Just kidding not a real product that is in development, but one day I'm sure it could be. But you see the point? Would you still feel it's Zero's job to test each and every one of these aftermarket chargers on each of their bikes in all sorts of conditions each year? Of course not.
And because of that I can say with a high degree of certainty Zero will never "certify" the Elcons, aftermarket meanwells, the Diginow or any other chargers that currently work with Zero's. It's just not gonna happen.
Does that mean you should never put an aftermarket pipe on your Yamaha or put an aftermarket charger on your Zero? Or Jailbreak your iPhone? Or remove the tags from your under your mattress? Or anything else that voids the warranty on hundreds of items that people use every day?
Use common sense. If bikes were blowing up from aftermarket pipes, then people would talk about it and not do it any more. If using aftermarket chargers for the past 4 years like the Elcons was causing some problem to the Zero, then people would talk about it and not do it any more. If jailbreaking your iPhone was causing it to crash permanently and Apple said it's your fault, buy a new phone at full price, then people would talk about it and not do it any more.
Point is, Zero might embrace these chargers knowing that they will help more people buy their motorcycles, but I wouldn't hold my breath if you are waiting for them to ever certify it. That's never gonna happen.
I know you like to worry about things Bonkers, so I am recommending you buy the official Zero Charge Tank this spring! First of all it is a great product! And it lets you charge at 3.8 kW combined! That's 3 times better than ever before! And especially if you don't really want to take really long trips, it's perfect to charge at that rate. Let the braver early adopters who want to travel farther and charge faster test the new aftermarket products for you until you think the sample size is large enough to satisfy your concerns.
