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!
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.
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.
I see they also invented a new connector standard, Nano-USB Type C.
? Are you talking about the lightning connector?
You'll want to duck for cover if the battery gets punctured on this one.
Its only comparable to tens of KGs of TNT, stop worrying about it.
I don't think you'll have the chance to wait for a puncture before it spontaneously explodes
The power of the sun, in the palm of my hand!
Hey Vegeta, what does the battery say about its Ah level?
IT’S!!!… nine thousand.
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.
What, my house used 78 kWh yesterday.
Have you tried not mining bitcoins?
Yes but I haven't tried not living in the arctic..
you should get some asics and mergemine while you heat your home
You are off by a factor 1000 on the household power consumption (I think these numbers are without heating or assumes that you don't have electrical heating?). And the voltage could be anything on a magical battery ;)
Whoops, you're right the values for yearly cosumption should be x1000, or in MWh. So, it's just enough for a day or two.
That fits with people's stories of running their homes from their car battery for ~3 days during power outs.
Why does that device have rocket engines?
That's the heat exhaust. 9 million mAh can get really hot
The picture talks only about stored charges, not energy, maybe it gives only a couple nano volt.
I think 45 kWh is more than I use in a month, so I'd love to take this baby to a restaurant or something, "forget" it, bring it back home and profit
I'm ootl. "Forget it"?
Like just leave it there for a day or so in an unassuming nook to charge up
Oh....yeah, I'm a moron. It's still early morning. Makes perfect sense.
Five year warranty is nice.
"Vegita, what does the lab equipment say about that battery bank's power level?"
"It's over nine million!"
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
