Solar technology is improving as a whole.
So i decided to upgrade to the 100 watt panel.
On the far upper end of the spectrum we added the powertraveller falcon with an impressive 40 watt capacity.

I purchased the anker powerport 21 watt and aukey 20 watt portable solar chargers within the last week.
Both three panel fold outs were arranged in nearly identical positions on a small table in my back yard.
The foldaway stand of the nomad 20 makes it easy to set it up hang or lay it down in the best possible way.
The goal zero nomad 20 solar panel is a lightweight foldable 20 watt usb solar panel which in combination with a power bank is capable of powering smartphones action cameras and other usb devices.
The anker has delivered a durable well made product.
While each panel performed well their metric ratings.
Poweriq delivers the charging speed up to 2 4 amps per port or 3 amps overall under direct sunlight.
During a week long power outage last year i used the battery to watch the evening news and to recharge lights and things and with the 20 watt panel i was loosing about 10 20 battery charge per day.
