Solar charger (real life)

I've had this a while, now, and use it as needed. It works as advertised. I have added a USB car charger port and a wall charger, and a 10' usb to usb mini charging cord, to make it a complete, charge anywhere kit (all fits in the pocket).
Even at near dusk, it is still charging the battery pack with @1wt. (Car charger supplied by my company is only 3/4 of 1wt. ) and just laid open on the dash, it was still working at 5:30pm on a snowy winter day. I've added clips to my pack to deploy it while walking (at reduced power due to angle) and laid it on the roof, during a power failure, to charge up the wife's phone (to her amazement
Other than being ridged, and breakable, I can find no fault with it, it works. (Red shows charging at @1wt, blue shows full charge when unplugged.)

 

Great review!.... nice watch

 

I wouldn't know as I do not have a goal zero.

 

My friend brought one of these to camp. Amazon.com: =Power Upgraded= Uritc 20000mah Car Jump Starter Booster Emergency Power Source Emergency Auto Start Power - 400 AMP Peak & Ultra-bright LED Flash Light for SOS & High Capacity Power Bank for Cellphone Tablet Laptop - UJS002 (Green): Automotive His was 24,000 mah, if I recall. He charged up five phones over the weekend with it. He never tried jump starting a vehicle though.

Anyone have any intel? Paired with a solar panel, that might be pretty good if it actually CAN jump start a truck or van.
