Difference between wall outlet and 800 watt gas Inverter generator

I have an Anker 20000mAh power bank that says it takes 6 hours to fully charge, but using my Sportsman 1000Watt/800 peak watts gas Inverter generator it is taking a little over 8 hours.
I have a larger Firman 4500watt/3750 gas generator, but I don't think it's practical for charging USB devices, uses too much gas. Haven't tried it because really wouldn't want to use it this way.
Don't have access to a wall outlet, but thinking my 800 running watts just isn't doing as good.

First, Anker isn't exactly known for accurate product specifications. Their products often have the usual Asian over inflated specs. I suspect their 6 hour charge time is "optimistic" or just a rough estimation. So, I doubt the 8 hour charge time has anything to do with your generator. If you have a Kill-A-Watt meter use that to see how much wattage your power bank is consuming while charging. I suspect it's not taking anywhere near 800 watts.

It has nothing to do with the generator. The generator does not limit its supply to 800 watts. If the Anker needed more power than the 800 watts it would try to take it and trip the breaker.

It does not matter how many watts the generator puts out.
How many amps does the USB charger that you are using put out?
Also USB 3 can charge faster than USB 2
And 3.1 faster than 3.

I agree with Pilot Dane that the specs probably came from a test where one bank charged in 6 hours in perfect conditions, perfect temperature, and then might have been rounded down anyway. Specs these days are 'loose' and rarely confirmed by anyone other than some review sites if they have the equipment to do so.

Your generator definitely isn't the limiting factor. If it has a single 2.1A charging port, that's 10.5 watts. So in theory, you could be charging 76 of these power banks on your generator.

Not sure what your goal is, but have you looked at solar chargers?

It would also depend on what they call fully discharged and the condition/age of the battery. But it is definitely not the generator that is causing the long time.

I think your doing pretty good from what Anker says themselves.

I tend to avoid gas generators for any purpose so I can't really say more than that on this subject except to agree on a better USB charger/cord if needed--that will make a difference if the Anker can withstand being charged any faster. It has safety features in place on its end for overloads and overheating an such from what I read.

I seriously doubt a generator has anything to do with the issue...but like I said, i'm not familiar enough to speak on that end of things.

I am using a 25' 16 gauge extension cord plus I also have a 6' 16 gauge swively ring style extension cord with 6 outlet plugs plugged into that (the 25' extension cord). I am using a RAVPower USB 4 port wall charger.

RAVPower 4 port wall charger

It says the input is 1.2 A Max, and the output is 40W total.
Also has iSmart. Looked it up and got this:

An iSmart 2.0 charger optimizes its output to both devices that are plugged in. You get an even charge distribution, so your devices power up quickly and efficiently. What's more, you can charge any two devices together. ... then you don't have to think about which device you're charging where.Mar 29, 2019
So, could the extra long 31' of 'two' extension cords be a problem?

I do not believe you have a problem.
Do this test before you blame the generator or the cords.
Plug it into a normal wall receptacle and see how long it takes. Make sure the discharge state the same as when you try it with the generator.
It is the only way to know for sure.

I do not know the exact Anker you have as I could not find a 20000 with a 6 hour charge time,
The following is from a 26800 unit
—a full recharge takes just over 6 hours while using both input ports (wall charger not included)

Do not have access to a wall outlet. Living off grid.
This is the device:

Anker 20000 power bank

Might have been mistaken about the 6 hours. Found this on Best Buy website:

Best Buy question and answer

Would the fast charger make a difference?

I found something similar on another site. You need an optional fast charger to get the quick charge.
