Fastest ebike charge?

It was only a joke.
It's the Arc Reactor that Tony Stark uses to power his Iron Man armour in the Marvel universe.
I think we are many centuries before we see a fusion/nuclear reactor this small!

Even though in Back To The Future II there was the Mr Fusion Home Energy Reactor in the future of 2015!

I felt certain that a machine which harvested (greater than) the totality of the energy contained in a banana skin, would power me to work when I grew up.... but I mostly work from home, and I'm yet to grow up!

They say fusion power will be available in 10 years, but they've been saying that for at least 80.

No, I'm sure it was a whole 15 years before availability in 1970 (maybe that was just the pessimists?)

It's been been a known possibility since (slightly before) the 1920s, but promised as being "Just around the corner", for far less time:

https://en.wikipedia.org/wiki/Timeline_of_nuclear_fusion

...but of course the sun was an early adopter of the technology.

I fear that fusion power packs for ebikes, may be a several tens of tens of years prospect... the "Glowing thing", in sci-fi films for quite some time yet.

that glowing thing maybe sooner than expected.



The MagLIF device can be quite small.

Once miniaturised and installed, that'd put hairs on your chest! (or burn it all off, plus your chest and everything it's attached to[or "near" to]), and they're yet to switch the darn thing on! It's been featured all over the place for years. They may find oodles of helium-3 on the moon:

https://www.technologyreview.com/2007/08/23/223985/mining-the-moon/

.. which explains much of the renewed interest in that other (smaller) big glowing thing in the sky:

https://en.wikipedia.org/wiki/Magnetized_Liner_Inertial_Fusion

They're always setting new records with various designs of hot new glowing things:

Ever 10 years away...

Pistol Shrimps lend a claw:
It's an interesting idea and they are working hard on it but I can't help the feeling that his scheme is a peashooter. Every time some lab claims a new record on plasma temperature and stable time, the goal post seems to move a little farther.
Still, good luck to the FLF's team. They do very good work.

We see supercapacitors in ebikes well before fusion power charges them up from power stations - can't wait! Lighter, likely less polluting, cheaper to make, faster charging... The future in sci-fi movies used to be blue, now it's a sort of turquoisy greenish glow...

I was catching up with nuclear fusion progress, now that all the planet's richest people put their money in fusion tech startups Bezos, Gates, Musk etc all did.
I came across an interesting comment by Kolemen, a big name in the business:
It (nuclear fusion) is a bit like flying. Humans tried to fly all of recorded history. We had Greeks jumping off cliffs. It wasn’t until the beginning of the 20th century that really it was mastered, but after it was mastered it expanded everywhere. Everybody started to fly.
Koreans, Japanese and Chinese are also catching up. It seems we are at the critical stage 'fusion burn' anytime in the next 5 years.
Still, fusion is about 100 years behind flying.

Every little part of the fusion cracking problem is a set of lifetime's work for a collection of poor scientists - we can keep an overview and make bets but unless you or I are willing to get stuck into equations and processing data (and even if), we can but guess.

As regards Bezos, Musk etc. It's a good bet if it ever pays off, because humanity would be able to build megastructures like Dyson spheres:

https://en.wikipedia.org/wiki/Dyson_sphere

... and populate the universe. But not in my lifetime methinks, unless they can bring my cryo-frozen head back to life intact.

All very interesting, but going back to the original question, because I'm confused.

My bike has a 17 amp battery, came with a 2 amp charger (which is the same as both my Samsung tablet and phone) , and therefore tests my patience that it takes so long to fully charge.

Why does a tiny mobile battery charger have the same rated output as a much bigger bike battery?

So to curb my impatience should I get a higher output charge (are they available?) and if so would it shorten the life of the battery?

My current phone now has a fast charge facility (2 hours) Can I look forward to battery failure earlier that on my past phones?

Battery isn't 17a, it is 17 amp hours a capacity rating of the cells.
I8650 cells are different to the high rate polymer cells used in other devices, faster charging will age the battery a little quicker. A slow charge rate is always best for li-on.

You charge these ebike batteries at 0.2C, which would be 3.4 amps for a 17Ah one. You can probably go as high as 4 amps. The charge mosfet in the BMS is normally rated at 5A, so any higher puts that at risk of blowing unless you open your battery to see what's in the BMS. Also, any charge fuse is normally 5A too.

You can get 4A chargers from BMSBattery.
