That depends on whether 1500mAh worth of electrons in a capacitor is the same as 1500mAh worth of electrons in a battery, I realize this kind of question does come up often on this forum.
Indeed, I do not know of a fast charger that can dump 1.5Ah in 5 minutes = 20A needed. Maybe zapandgo knows?
Add: You know what I would think would work instead? If the supercapacitor is a high voltage one. Since there is usually DC-DC conversion needed anyway between the charge storage and the USB port. Then maybe you can charge it with a 2A charger. But at 50V.
But no matter how you want to adjust the current and voltage there is no way a 100W power supply would fit in a wall-wart... pretty sure EU has too many rules to not make that work. This is where the version that plugs directly to the socket might work instead (340V DC woot), but I'm very sure that will never make it past EU.

Well if you assume that the charge/discharge cycle on Lithium cells is totally reversable or they have nice electronics to squeeze the most out. The reviews don't cover that. Certainly when full they should be the same.
You get a 40A charger with the battery. That is their value proposition. Poor value, but value nonetheless.
How are you ruining the dreams and lives of kickstarters... surprisingly they have employed engineers to do the circuitry....
Further super caps are used a lot in electronic systems to provide power or back up power, because of their advantages over batteries, it is becoming common practice now... especially as the power density storage of the caps increases.

Often charging or using higher voltage caps gives you more energy storage, most instances where caps are used you find some sort of switcher circuit, done numerous ones including some headsets where fast charge is a field requirement, also had AA battery back up, because there is a chance you can replenish your AA batteries from the dying or wounded
. The graphene caps just allow more joules per mm2...
On a battery based not you can now get coulomb counters.....

Ever since, I been the Chief
So I ordered a salad, and the waiter said,"you want some bacon bits?"
I said, " pardon?"
He said it again! "You want some bacon bits?"
Lost it! Snapped!
Flurry to the solar plexus,a tomahawk jab, and a sockeye left hook to knock him out.
No body calls me a bits!

Went to AXPONA this weekend, plenty of snake oil to choose from. My favorite was a cable company who patiently explained electromagnetic theory to me. Their thing was putting magnets everywhere, including in plugs in the wall socket which connected to nothing else. A sample of their breakthrough understanding in physics:
Seriously, with deep thought and remarkable innovation like this, how can anyone ever be cynical about the fashion audio industry? They have won numerous accolades from reviewers, who are mental giants walking amongst us benighted pygmies. I feel ashamed for my past doubts and humbly apologize.

Until now, I didn't know that spin and charge were the same thing, or that it was the spin which caused moving electrons to interact with magnets. Likewise, I had no idea that the way to model a signal flowing in a wire was to look at electrons traveling through a vacuum.
From one of the reviews:
The man is a genius. We should be grateful.

$20,900 for 1m of power cable. More than most would consider for the whole system.
Glad I'm happy being a rank amateur
