Just two years ago my car’s 50 kWh battery weighed around 350 kg, now you can get a 45 kWh battery that fits in the palm of your hand!

The picture talks only about stored charges, not energy, maybe it gives only a couple nano volt.
I see they also invented a new connector standard, Nano-USB Type C.
Hey Vegeta, what does the battery say about its Ah level?
IT’S!!!… nine thousand.
I love how we still needlessly use so many zeroes instead of just calling it Ah. Phones with 5000 mAh batteries. Or you know, we could just cal it 5Ah battery. Chinese are even further obsessed with this just adding zeroes because the more zeroes the better!
Even better: we could use Wh instead, to not constantly correct for voltage!
I’ve wondered in the past why, for example, 1000 kilometers are still referred to as kilometers.
Hehe, nice catch. Technically, under SI standard we could call that 1 megameters… It’s mostly we rarely address distances beyond 1000 kilometers in day to day life so kilometers still make some sense. Where under Imperial units, there isn’t any unit above mile. For batteries, we don’t really use anything less in phones anymore, only smartwatches and earbuds use capacities under 1000.
People don’t use megameters enough that you can rely on them knowing what it is nor have an intuition for it even if they technically know.
They should.
Judging by those USB plugs that hand is enormous
I’m tired about all these jokes about my giant hand! The first such incident occurred in 1956…
At first, I was concerned about that much energy in such a small package.
Now I’m afraid of that giant hand.
The power of the sun, in the palm of my hand!
Its also 9000000000000000000 MAH at 0.0000000000001V
This is why mAh shouldn’t be used to measure battery capacity
Its actually useful because a battery has a specific operating voltage. It should be required to put both.
Why does that device have rocket engines?
That’s the heat exhaust. 9 million mAh can get really hot
Five year warranty is nice.
Could this power my home for 8 to 10 years?
- It’s designed to fail the day after the warranty expires.
It’s impossible to say, but if we assume it’s a typical Li-ion battery supplying 3.7V, then:
9 kAh x 3.7 V = 33.3 kWh
So, it would be enough to power the average American house (10 MWh/year) for 1.2 days, or 4 days for a typical European flat (3 MWh/year).
Edited wrong yearly consumption
I think your math is off given that just a typical US consumer full sized refrigerator can use ~650 kWh/year and still be considered Energy Star qualified.
Someone buy this so they can tell me how big it is, and how long before it dies for good. Please.
Smaller than a credit card, didn’t last opening the package
