It's heavier than I'd like, but not so heavy that I can't carry it in my backpack. The real value of this battery pack is the circuitry, which is done right. The battery won't overheat, it can reliably do pass-through charging (charging a laptop and 2 USB peripherals, while also charging the battery while plugged in), and it doesn't require a manual selection of laptop voltage.
Laptops: When I tried to use the included power adapters with the Sherpa 100 on my laptop, I wasn't able to get the laptop to charge. As an IT person, I know that laptops have so many different types of adapters and voltages. The adapter fit, but I assume the voltage was not correct. So the inverter comes in handy but requires the laptop power adapter in that case.
Battery Health and Life: Some reviewers may complain about battery life or the battery not working after a short time. In terms of life there is no magic number of charges it will support for "your" device. All devices are different and require different amounts of power. The Sherpa 100 provides approximately 98wh (or about 100 watts of power for one hour), how you use it is up to you. Please also keep in mind with these batteries that you need to use them. Don't buy one, put it on the shelf, and expect it to work when you need it a year from now. The chemical structure of the batteries will crystalize if not used as directed. But this is easy to do. Leave it plugged in or in my case I pull it out and charge my various portable devices and phones with it as a means to be lazy and continue using my phone while away from an outlet.
Solar: If you plan on adding a solar panel to your kit, be sure to do your research. Check Goal Zero's web site. There are several panels available and they can be chained together depending on how much you are whiling to spend, how much space you're whiling to consume to transport them, and how long you're whiling to wait for the unit to charge. They don't clearly state so on their site, but this unit will work with two Bolder Solar 30 panels which can be chained together to charge the unit in 3.5 to 7 hours but 2 Solar 30 panels will cost more than the Sherpa 100 itself.
Aug 2016 Update:
I still have and use both the Goal Zero 8 and the Sherpa 100. I think they've both lost some of their charging power, which is expected, but they still work sufficiently for my needs. To clarify, I've used and abused both of these. I've left them in hot cars, I've failed to charge them for a couple months at a time, but they keep on going. Much more reliable than my iPhone battery! I primarily use the Sherpa 100 when by iPad runs out of power. But the Sherpa 100 has proven a must when traveling. 2 iPads, 2 iPhones 6's and a Fire Tablet and they all have to be charged. When power is short or not convenient, the Sherpa 100 gets used (frequently) on these trips. Since it has 2 USB ports with enough power to charge a tablet, this unit is gets used a fair bit.
