In this day and age, I would not be surprised…

Must be for the two pack. :-/

If you look closely at the picture,it doesn’t have a micro USB port. Instead it has a super-special “mirco” USB port.

Also, the back has some interesting specs, which could be useful, as the listing is lacking anything but the physical dimensions.

The battery has a capacity of “8000mAh”
The solar panel is… “Solar Panel: 5V/200mAH”

I wonder is they meant to use “mAh” for the battery and “mAH” for the panel. They certainly shouldn’t be in the same units. Unless the solar panel will die after one hour, which might not be out of the question.

mAh is a measure of capacity. The solar panel should be measured with a rate. mA (or mW) not mAh.

Assuming they meant 200 mA at 5V, that’s 1VA, or 1 Watt.

8000mAh at 3.7v is 8Ah * 3.7V = 29.6 VA hours, or 29.6 Watt hours.

In an ideal world, with 100% efficiency and realistic specs, it would take about 30 hours to charge via solar.

Assume, say, 50% efficiency on the solar panel and 80% on the DC/DC conversions in the power pack, and you’re talking 74 hours to charge–over three days.

And don’t forget that in most places of the world, the sun doesn’t shine for about half of that time. So 6 days.

Between that and the piss-poor translation, this thing just screams, “POS!!!”

No, thanks.

super-special “mirco” USB port. Cool…I just got a new Note 7 and that must be what it takes to charge it because the regular micro USB plug doesn’t fit

So in reality after everything said this thing is useless!

Am I correct!

You are paying for a gimmick with this particular device. I love the spare battery pack concept. I use mine fairly often. I bought 2 of these https://www.amazon.com/Lepow-U-Stone-12000mAh-External-Portable/dp/B00E3GXJDC when they were on sale for like $12 each off of some deal-a-day site last year. These things have enough capacity to fully charge my phone from 0, 3 x in a row before I need to recharge them- and it charges them quickly. It holds a charge forever, so even if it sits idle in your car for 6 months, that charge will still be 90-95%. Just browse Amazon and check out the reviews before you purchase a battery pack.

This one is $11 (freeship on prime) and it’s rated at 10,000mAh, and has a lot of good reviews. https://www.amazon.com/dp/B00VWV8LD4?psc=1

Sakes alive, between this and that lousy backpack Woot discussions has saved me some heartache from buying some crap today. Thank you, random brilliant strangers!

Woot, you need to step up the quality!

I looked at buying a similar one, back last year in the spring for a 2 day Bike ride. I decided I was better off with a non solar one with over double the capacity for about the same price as a solar one. It would take several days to charge from solar.
