@JohnO Thanks for reaching out!
The lineup of Goal Zero products is a great way to get power to places that don't normally have it, whether that's far from the grid while camping, or close to home during a power outage. The Goal Zero 1000 paired with Boulder Briefcase solar panels is a great place to start, particularly if you are hoping to power bigger items like tools.
In terms of durability and longevity of the batteries, if you follow the manufacturer's guidelines of keeping the unit continuously plugged in, when possible, and help maintain the battery by allowing it to drain to 50% and recharging it (3-4 times per year) you should be able to rely on this product for power for many years to come.
Some other considerations:
The unit is portable, however, at 40 pounds that is still a good amount of weight to carry for anything other than a short distance. You'll want to keep this in mind when you think about 'off-grid' projects and whether you have a 4-wheeler or other motorized access to your site. Goal Zero does sell a Yeti Lithium Portable Power Station Roll Cart if you're looking for an easier way to move the unit.
If you are purchasing solar panels to charge your unit, you'll want to consider the following stats:
Wall Charger (5A): 18 Hours
Nomad 50: 31-62 Hours
Boulder 50: 31-62 Hours
Boulder 100: 15-30 Hours
Boulder 100 Briefcase: 15-30 Hours
Nomad 100: 15-30 Hours
Boulder 200 Briefcase: 8-16 Hours
Boulder 100 x 3: 5-10 Hours
Boulder 200 Briefcase x 2: 4-8 Hours
Boulder 200 Briefcase x 3: 3-6 Hours
If you plan on linking multiple Boulder Briefcases and/or you want some more flexibility in where you place the solar panels, you'll want to look at Goal Zero Accessories for extension cables and adapters to make it work. You can also call Yeti at 1-888-794-6250 and talk through your plans and how to best optimize for your power needs.
Hope this helps!
