That is an impossibility! that is 900 Ah in that pack when an auto battery is 60 to 90 Ah.
I read a bit farther and found this:
Manufacturer's Nominal Capacity: 900,000mAh; Actual capacity: ~15000-18000mAh

That is only 15 to 18 Ah which is not beyond the realm of possibility but still higher than I would bet. Then I found this:

Note: 900000 mah is a theoretical capacity from the company.You can charge 3-6 times(depending on your phones conversion rate) at one go.we guarantee 3-4 times of charging capability.

How many mAh does it take to charge a phone? Multiply that by tree and you have a good idea of the actual capacity of the charge pack.
The solar panel is "rated" at 1.2 watts which is 1200 mW or 240mA. It would take 62.5 hours of direct sunlight to charge your charger with the solar panel after using it. (2.6 days of noontime sun)
Beware of outrageous claims and read the fine print.

Since I know how much power 900 Ah is (see below), I had to have a look too.
I figured out how they got the "theoretical" mAH number. They are talking about over the lifetime of the unit.
Let's say it will charge with 1500 mAH and supply that, and it can be recharged 600 times. This equals their outrageous 900,000 mAH rating.

Here's a 900 Ah battery. It weighs 3,120 pounds and a used one costs $3,700:

On topic: @jimLE , The unit you got will probably work great for charging a phone out in the wilderness. Plenty of reviews from lots of happy buyers.

unless i have to leave due severe storm or what ever.i'll be using it at home.even then i'll be using it to keep up with the weather reports.and maybe listen to some music.and it'll be good for camp outs as well..any how.we will see how it works out and try out the different functions.
 
in the 2nd pic is of the 2 chargers i have.the one on the lefy.I've had for at least 4 or 5 years. if not longer.and it has to be pluged in to be recharged.and good for up to 23hr23hr's to 25hr's for phone recharging only.the other one is my new one.it can be recharged by plugging into a outlet or usb port.or Solar panel.the other pic is of my bathroom window. it face's south.that allows me to recharge it there.and i can.seeing how i have.we had a planned power outage 2 or 3 day's after i got it.on account oncor electric replaced power line's. the solar charger practily paid for it self that day.power was off 4 to 5 hour's that day.i made at least 3 calls to friends.i used my phone to set it up where i recive email's. and text message's about outages in my area.that includes making phone calls and getting onto the internet alike.in which the charger and phone alike remained charged up the whole time.i can plug my phone and the charge that requires power into my. solar charger.in which all 3 will get recharged at the same time.but only when there's ample sunlight.it turn's out to be a great buy for me.

I have a similar unit that I use with my LabRadar chronograph. It is rated at 15000 mAH (15 amp hours) and It lasts all day at the range and has never gotten below 3/4 charge. I charge it on USB and it takes about 3 hours after a full day at the range. The unit can run on a single 9 volt battery but it won't last even two hours on a NiCad battery. It takes a bit of power to send out dopler radar beams fast enough to record velocities at less than a yard apart tracking a bullet at 3100 fps. The battery is great for that and since I don't have a portable phone that is all it is used for.
