Simple To Use Everything I Needed Came With ThisI use this mainly for keeping my phone charged while at work. I can plug in without ever needing to worry about leaving my phone when leaving the room. If I go, I take the phone and Sherpa with me. I have used it to charge camera batteries, AA batteries, my laptop. And when I had contractors working around my yard, I brought the Sherpa out when their radio battery pack died. Not only did the Sherpa power their radio, it also charged the battery pack at the same time. They were very impressed. I bought it for backpacking trips, but have not yet tried it in the field. Soon though, very soon.

Great chargerGot the Sherpa 50 for an Asia business trip. The Sherpa 50 has given me some great piece of mind. I wasn't worried about not having enough juice for my laptop and cell phone. My cell is my life line and I've been in those situations where every drop of power counts. So cool not to have that anxiety. It also charged my laptop and phone really quickly. I don't know how they do this, but it seemed to just discharge the batteries and charge the phone and laptop really fast. I used the direct laptop port with my Lenovo and it worked like a charm. Got a few people asking about it too. I'm looking forward to taking it out backpacking to power up my phone, camera and laptop. Should be great.

Failed due to moisture in tent after 2 expeditionI paired this unit with the 20 watt panel at base camp and it worked like a champ on a successfull K2 expedition (very rugged approach and variable weather). I just completed a successful Annapurna expedition and it died half way through. I always keep the Sherpa 50 out of the weather in my vestibule but condensation in the tent triggered one of the temperature sensors and shut it down. It has not recovered. I know this isn't water proof. I'm an electrical engineer and not affraid to take it apart but the 2nd temp sensor is elusive without a hardware diagram. It has been a great system and very rugged but I'm sad to lose something this expensive on it's second expedition.

One year ownership reviewSo, it's been just over a year since I bought my Sherpa 50 from Cal's Sporting Armory online. My Sherpa 50 has performed well over all for the first year, but now the built-in LED light is really dim and not useful. And the switch for the 12V/Laptop outputs doesn't function properly anymore, when switched to the OFF position either the 12V or Laptop light illuminates so basically the switch has gone bad.
With that stated I'd recommend buying this product however I'd highly recommend buying a retailers 1 or 2 year extended warranty/replacement plan because you're out of luck after the Goal Zero one year warranty expires.

DME - CPAP ExperienceI purchased the Sherpa 50 for its compact size and ability to add an inverter right to the pack it's self, no need to carry 2 separate items. While camping our Generator went down and so did the only 12v inverter we had. Suffering from Sleep Apnea is life or death, well I remembered I had our Sherpa 50 in the bag, it gave me @ 4 hours of run time, not quite a full night sleep but better than nothing. Gave it a full charge the next day and only got about 3 the next night worked well, but seemed to need just a bit more. Really like the USB / and flash light / wish the LED had a bit harder switch, got bumped and came on several times. Needs a switch like the one on the inverter / flat and a bit harder to switch on..

Charge it all!I have owned the Sherpa 50 battery pack, and Nomad 13 for about 9 months now, and this thing will charge anything!
I spend alot of time filming in remote places, such as Southeast Alaska, Grand Canyon, Desert Southwest.
It can charge my cameras, computer, and even my Phantom Gopro Drone!
I recommend this product to anyone that has electronics to use in the backcountry.
I even use the battery back in airports and while traveling to give my gadgets a bit extra juice between outlets.

Power for amateur radio Field DayField 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.

Sherpa 50 Saved The DayVery useful and handy to have in many situations. Travel, around the house, backpacking, motorcycle camping. My truck broke down in western Kansas just as a blizzard was coming through. The freeway was closed up ahead and I had no way to get to a hotel on my own. My phone was just about dead so I plugged into the Sherpa 50 and was able to alert my family as well as contact the local Sheriff's office for a ride to a hotel 30 miles down the road. At worst my life was in danger, at best it would have been a truly awful night in below freezing temperatures inside my truck. Goal Zero products have come in handy plenty of times, but this time I was truly grateful to have the Sherpa 50 along for the ride.
