Purchased this unit for a Yeti 500 as the Boulder 100 Briefcase, while providing excellent power is heavy. Today, June 7th, at 4pm US/Central in Dallas TX, on a full sun day (no clouds at all) I am getting 38W (as shown on the Yeti 500 display). BUT, the Boulder Briefcase 100 is providing 71W (best I've gotten from the Boulder is 91W). Checking at different times and conditions, the Nomad seems pegged at a hair over 50% of the output of the Boulder (panels sitting side by side for the comparison). I will probably keep the Nomad as I got it on sale, and it's still something for camping to charge phone, etc, but it doesn't not match the Boulder briefcase. I'm giving it a "Fair" rating as the price is high and the output is so low compared to the Boulder Briefcase (max 45W? compared to Boulder 100 at 90W?). The build quality is excellent, and the unit is far lighter and easier to carry than the Boulder suitcase. I just wish Goal Zero would be upfront that the Boulder units appear to be heavier but provide a higher level of output consistently than the Nomads. No one should have to buy 2 different units to test to figure this out. Or call this unit the "Nomad 45" and sell it for half the price.
Easy to hook up straight out of the box, I will give them that.
I am at sea level and charging a Yeti 500x on a fully sunny day in California. 100w Nomad panels, topping out at 55w (per the display on my Yeti 500x). I know, the other reviews told you and me about this already.
I got curious, so I pulled out my multi meter. I checked the voltage (DC) at the 8mm output connection on the panels and got a reading of 20.65v, which is within the advertised range. Cool. I then checked the amperage with my multi meter set for DC and got a reading of 3.78 amps. Well you know, I am not an electrician or an electrical engineer or anything, but I am pretty sure 20.65v x 3.78 amps should equal approximately 78 watts. Seems dumb that if the panels can put out that kind of wattage, the manufacturer would want it to show up when you plug it into the “power station” of the same brand. Instead I only see 55w, which seems a bit low, even if there is some drop for the controller in the Yeti.
Anyways, I attached pics with my multi meter display visible for reference. Just sucks for the price. But again, the other reviews told me so.
I have been using Goal Zero products for years as backup at home and for camping. Will be using this with my Yeti 400 for camping. Excellent quality and durability. Will definitely continue to use Goal Zero products in the future.
Rating this as one star b/c the fact is that it can't get 100 watts, so it shouldn't be priced and sold like that. Like others, I've tried it high elevation, no clouds, direct line to full sun - several times - and never seen it above 61.It's portable and convenient, yes. But again: if you pay for 100 W, that's what you should get.
