I use the Yeti 1250 in our home in Zimbabwe.. The USG provides us a diesel generator to use when the spotty power grid cuts out, but I'd rather not pollute when I'm just running a crock pot and internet router. The Yeti sits in our kitchen to provide power to our kitchen appliances, iOS charging station, and network extender. The Yeti was my go-to plan when I heard the grid was as dodgy as it was in Nepal; even though it's better, it's still my plan, as the power can be out for up to 24 hours here. It's great as the LCD gives me live reporting of how many watts I'm getting from the boulder panels (2 panels), typically 20-40 watts in full sun, and also what my appliances draw. Apple Time Capsule: 20-25 watts. Rice Cooker: 400+ watts (have to figure out a better solution there). Kitchen aid mixer 20-60 watts (depending on speed). There are a few downsides to the product, most of which are solvable. 1. There is no included 8mm extension cable; the 6' cables exiting from the boulder panels (which are chainable, awesome!) are too short to place the panels on the roof (just one story up, and perfectly pitched) and put the Yeti on the kitchen counter inside. I'm ordering a couple 30' extension cables to fix this. At the current price-point, one would think the up-sell opportunities are there. 2. There is no 200v output! What? EVERY GZ inverter so far has had a dip switch for converting this, so I'm amazed there is not the option. I'm going to try out a local cigarette lighter ("car power" in the parlance of our times) 12v - 220v inverter and see if that works. Otherwise there is no way to power our 220v refrigerator 3. There is a 6 month warranty. Seriously? I bought this in the private pre-sale earlier in 2012, and I am just now getting this up and running, it having been delivered in our effects to post in November. My six months are long gone. Not that was that worried; this product is in the core of GZ's focus and everything else I've had* has been top notch quality. 4. Lead acid, definitely traditional and will be interesting to replace. I look forward to working with GZ on reclamation and replacement of the battery in 3-5 years. 5. The handles for the yeti (the dolly handles) are not collapsable. I removed them after placing it and put them in the pantry. When we take this on Safari, I'll just leave it in the vehicle. My bottom line: for globe trotters in long term assignments abroad with dodgy power grids (actually not that uncommon), this is a real asset. *Includes Escape 350 batteries, Escape 30w briefcase panels, Sherpa 120 power pack, Escape 150w jug, light-a-life lights, 400w inverter, sherpa inverter, fold-up 27w panel, fold-up 3.5w panel, fold-up 7w panel, guide10 and guide 10plus, boulder 15 panel..
Duracell batteries are small in size but big in power. They are always the first ones that I look for on the shelf. I am willing to spend more money to get the better quality that Duracell provides. We have a small child that has a lot of toys that take batteries. It seems the smaller toys that he has the more times they require AAAâ€™s. When we have tried to take the cheap route and but store brand or the provided batteries we have just had to replace them at a quicker rate than when we use the coppertop. Some of his toys still have the original batteries in them. Overall great battery.
The Power Tank is a great option for any astronomer who wants to take their scope further away from their vehicle than their cord can stretch. It also prevents you from depleting your car battery and possibly getting stuck somewhere in the middle of the night with a dead battery. It would probably work well for car camping for the same reason. I live in a forest and can't observe at home, so the power tank lets me get to places away from the lights of cars and buildings that my car can't get to. There's multiple voltage power outlets depending on what your device uses in addition to the two cigarette lighter outputs. The power input has multiple plug adapters to work in various countries across the world and tucks away into a compartment. The main light is great for setting up a campsite or something, but the red light is better for dark acclimation for astronomers. The radio isn't exactly spectacular, but who's really buying this thing for the on-board radio. There's even jumper cables to start a dead car. If you use a more energy-hungry telescope (or other device) the 17-amp will definitely last much longer than the smaller version. At any rate, it's a good value and because its so portable, you'll probably get a lot of use out of it. Like any battery, you should keep the unit charged as instructed in the directions to ensure long battery life.
I was so excited to receive these batteries from Duracell to try out! We got through batteries in this house like no other. Between me and my 3 year old we are always reaching for the battery drawer. I have to say I am so happy with this product! Once we popped these babies into our various items you could tell the power that is within Coppertop Batteries. I am so pleased with this product that this is the battery I will be reaching for from now on. Thank you Duracell!
