Compact, yet just as powerful

Let me first start by saying that the newest iteration of the Sherpa50 is superior in almost all respects to the old Sherpa 50. Be that the smaller form factor, the use of Li-ion over Li-Po, and the products adaptability to your everyday life. The new Sherpa50 has almost everything. To make this review a little more readable to the masses, I'll start out with my impressions of this device, and the results of months of stress testing I imparted on this battery pack.

Let me first start by saying that the newest iteration of the Sherpa50 is superior in almost all respects to the old Sherpa 50. Be that the smaller form factor, the use of Li-ion over Li-Po, and the products adaptability to your everyday life. The new Sherpa50 has almost everything. To make this review a little more readable to the masses, I'll start out with my impressions of this device, and the results of months of stress testing I imparted on this battery pack. And once the basics are out of the way, I'll lay down some of the technical information which people like me will find important. Based on how I rated this product, I'm sure you can guess I'm quite happy with the Sherpa50's performance and form factor. Having extensively used the older (and much larger) brother to the new Sherpa50, the newest version leaves my school bag, and backpack lighter, and with more space. Yes, the new Sherpa50 is half the weight, and takes up only 48% of the volume of the older version. This may not be important for everyone, but I don't have to tell those who backpack, or have to haul things on their person (bag, purse, pocket, whatever) how important a pound+ savings can be. Normally such an accomplishment comes at a cost, but not this time. So, what are some of the changes made? The biggest would be the changeover to laptop cells (6x 18650's, vs. 3 large LiPo's), and a much more compact circuit design. But GoalZero didn't just stop by making the product smaller; they added a beefier USB port (1.5A vs 0.5A, and yes, this thing charges iPads, and Smartphone's with ease), a cleaver attachable inverter (sold separately, though worth picking up), the addition of a laptop port (you can't use the laptop and 12v port simultaneously), and an LED light. The new Sherpa50 now comes with a regulated 12v port to keep some of your electronics happier. And I found total output to be fairly consistent with varying loads. But I did notice that the new design is a little less efficient when charging under solar power (requires more solar energy to acquire the same state of charge). There are also more apparent safeties built into this model. For the most part, these are good, because they not only protect you from a failure, but also extend the life of the device by limiting the amount of damage you can do to the cells. But under heavy loads, especially while charging from solar, I could trigger the thermal safety cut-off, completely disconnecting any external charge coming in. The older version of the Sherpa50 was less temperate on this issue, but on the same note, the older version appears to be degrading faster when it comes to maintaining maximum capacity. So, how has the new battery worked for me? Well, its main use has been powering my laptop (through the use of the attachable inverter) on an almost daily basis. In many instances I've used the new Sherpa50, with a few Nomad13's, to keep my laptop powered throughout the day without a plug in sight. Using the Sherpa50 to power your iPad (or other tablet) basically equates to 10-20hrs of use (depending on model) before even touching your internal battery. And if keeping your phone charged for days away from the city is important, well, look no further. So, here comes the technical stuff. First, I'd like to talk about the advertised capacity. Under a 1C discharge, initial capacity showed 51wh (±1.8wh), which is slightly above those quoted by the company (the original Sherpa50 only gave 43wh under similar testing). And with close to 60-70 discharge cycles now on this pack, it still shows a capacity of 47wh. Though data on the specific LG cells used by GoalZero are unavailable, similar models show an expected drop-off of 80% after 300 cycles, putting my results closely in line of a linear model. Cells come in a standard series parallel (3-3.7v series, 2 sets in parallel) configuration, using quality cells. Because the cells are charged to about 90% of their total capacity, there will be some degradation over the long haul (the ideal standard is to only use 65% of total capacity for longest life). But having designed/built a battery pack under similar parameters as GoalZero for the solar car of our University, we found longevity of the cells to be only a minor issue. To wrap up this review, the new Sherpa50 follows in the footsteps of its older brother. But the newest offering gives you more features in a lighter, smaller form factor, making this battery perfect for almost everything. Capacity in my testing has also increased by 18%, while battery safeties are maintaining that capacity longer. I really liked the old Sherpa50, but this new one I just love, that's about all I can say.

Not good enough.

Charges an iphone 5, and drops down to 20%, then I recharge for hours up to 100%, recharge the same iphone and power drops down to 80%, then I plug in my ipad to charge it, and it drops down to 10%. Its a very inconsistant battery, and the charge times are across the board. I've seen it charge my phone three or four times, and then some days I only get one charge out of it. I've plugged in my laptop for about 2 minutes then dies.

versatile !

By

from Santa Barbara, CA, United States

What really nice about this product is that it's really small and portable. I did actually buy the Sherpa 50 kit, which includes the nomad 13, the Sherpa 50, and the nomad 13. It looks cool too! Also, one thing that I didn't know I even wanted is the amount of input power this thing can recive, meaning since the Sherpa receives DC power its actually capable of receiving higher speeds of charge compared to some other powerbanks. Like ones based off of USB , they usually receive a limit of 5volts , 4 watts. The Sherpa 50 for example, takes in 32 watts peak this is awesome when using solar, because the flow of the current is much larger and therefore causing it to recharge faster than say I would my cell phone because that's also limited to say 5-7 watts. That's wat makes using the Sherpa 50 awesome, you can take much more advantage with one of the banks to collect more power, faster. I still haven't had a chance to use the inverter on it, I am honestly a little afraid to because its a modified sine wave, I'm not too sure if it'll damages my batteries. Overall its an awesome product!

Great Product

By

from Haymarket, VA, United States

I've been a fan of Goal Zero for the past few years, ever since I purchased a Sherpa 50 and two Nomad 20's for a recent trip to Nepal. The products worked flawlessly. I have since purchased Switch and Nomad 13 to add to my Goal Zero collection.

Power for amateur radio Field Day

By

from Pelham, NH, United States

Field Day is an event held annually that gives amateur radio operators a chance to test their mettle in emergency situations. My Sherpa 50 powered my radio for the 24 hour event, exceeding my highest expectations. Our team contacted hundreds of other operators nationwide with juice to spare. I have also used this system on the Boston Harbor Island national park campgrounds, seven miles out to sea. With this system I keep my phone, tablet, lights, cameras, and radio rocking all weekend. You can't beat the simplicity, reliability, and versatility. I have two, and I will get a couple more. Yes, they are that good.

I haven't used it yet, but it is a thing of beauty, and I strongly believe it will be as efficient as all my other Goal Zero products.

from Undisclosed

I got this product for Christmas I love it charged my phone my brother's phone and my dads phone and it was stil at 80% battry capacity at witch point I pluged it into a bolder 30 and it was charged to 100% in 1-2 hours. I took it on a ski trip and brought a nomad 7. it kept my phone charged on the Mountain but it was tricky to keep it at a functining temperature (30 degrees or higher). At the lodge I put my nomad in a window where it had direct sun light in 30 minits I got about 10% charge when I charged a laptop it drained the power pack fast in about 50 minutes to an hour it was at 60% and my laptop got about a 25-30% boost. I have no complaints and it was a grate gift.

Excellent portable power

By

from St. Charles, IL, United States

I own the Sherpa 50 for charging my phone or lighting up my campsite. When hooked up to a couple Goal Zero led lanterns I can cook dinner after the sun sets. I also have a Yeti 1250 and 3 Boulder 30 solar panels. All of them are great products.

Like the 'Noisy Cricket'

By

from Undisclosed

I use this unit mostly for traveling and working in Kenya. Its sweet spot is cell phones. And since everyone in the world, it would seem, now uses cell phones, the Sherpa 50/Nomad 13 is a handy combo-tool to have. The best part about this set is the size. Without the inverter, I can keep the battery in my jacket pocket, or on my dash, or just about anywhere. The panels fold up well and disappear into my backpack. The set is not only portable, but also discreet, and doesn’t attract any unwanted attention. At the same time, it charges gadgets extremely fast and my team can charge several phones or cameras a day â€" and do this for several days in a row before the Sherpa must be recharged. The main drawback is a necessary one with the speed and portability benefits: it can’t charge my computer. (For that I use the Sherpa 100.) It can, however, power my trail cameras, which is handy and saves me buying a bunch of AAs all the time. The little features make the set even more versatile. The LED is helpful for finding the flashlight you just charged, since the Sherpa is much easier to locate in the dark than a tiny headlamp. The thin metal cable is awesome for securing the unit to your tent, pack, or whatever else to make sure that wind and bumpy roads don’t bounce the thing onto a sharp rock.
