So I'm confused, this is an indiegogo fund raiser that funded in December of 2015. They raised almost $650,000 and they are still taking donations? Okay whatever, I think I must have that wrong, it seems odd to me. I'm not sure why a company that appears to be as big as ienergy is running an indiegogo.

Anyway,

I am far from an expert but.....

One thing I can say is I own a Goal Zero Yeti 1250. I never take it with me because it's too damn heavy to move. So weight is a huge issue that needs to be dealt with some how. Lead acid vs Li-ION could be a good thing, the one graphic shows 20lbs vs 103lbs for the same price basically. That would be awesome.

The second thing I can tell you is the solar panel makes a huge difference in how fast the system recharges. $169 for a 50watt panel (I assume Predator50 is a 50w panel) is outrageously over priced. You can buy a Grape Solar 100w panel for about $130 everyday of the week. If you watch you can buy them for $100 from Amazon and HomeDepot on sale.

At best most solar panels are only about 30% efficient and that's under excellent conditions (proper angle, temp, sun tracking, clear sky, etc.) By the time rookies in real life set them up you are lucky to get 20% of the rated wattage and you have to keep moving them to track the sun if you want to keep that high of output for more than about 30 minutes.

So one 50 watt panel will take well over 40+ hours of direct daylight to fully charge that 1100 Whr unit. At 100% efficiency, 1100/50 = 22 hours
At 30% efficiency 1100/15 = 73 hours, you get the idea.

The "Bronze System" that claims 24 hour recharge time with one panel is just flat wrong.....(Keep in mind that's going to be daylight hours only)

Also, these type of units have a max input because the batteries can only take a recharge so fast. The max input is probably around 300w. At 300w in put the battery could charge in 3-4 hours, but to get that 300 watts in you would need about 1000-1200 watts worth of solar panels

In the end, that indiegogo site, really doesn't give enough technical info on any of the products. I can't tell if a Predator 50 is 50 watts, 12v or what?? A quick google search says it is 50w, but even the ienergy website doesn't list the voltage, amperage or what type of connectors it has......
