It's definitely not roughing it, but at least you've finally gotten away from the noise of the urban jungle. And while you're looking forward to unplugging, you do actually need to stay connected. After all, you are the responsible one. The problem is, all of your tech needs to be recharged at some point. And until Smart trees with charging stations become a thing, you're going to need a battery. Lucky for you there's the Goal Zero Sherpa 50 power pack.

From your smartphone and laptop to your electric cooler and lantern, the Sherpa 50 can charge and power them all. A dedicated laptop port allows you to charge your laptop directly from the power pack; and the 12V DC port with car adapter keeps your cooler powered so your bevvies stay cold and your hotdogs fresh. And if the Sherpa 50 runs out of juice, simply hook up a Goal Zero solar panel and charge it up.

What you need to know:

  • Direct charging: The Sherpa 50 has 3 ways to charge your devices: USB port, laptop port, and optional U.S. (sold separately) or international AC inverter (not included). The USB port has a 5V output up to 1.5A (7.5W max), regulated. The 7.4mm laptop port has a 19V output up to 5A (100W max), regulated. The U.S. AC inverter (not included) has a 110V output up to 0.7A (75W max), 60Hz, modified sine wave. The optional international AC inverter (not included) has a 220V output up to 0.35A (75W max), 50Hz, modified sine wave.
  • Charges most devices: This power pack can charge USB and 12V devices with low to medium power needs, including smartphones, action cameras, headlamps, handheld GPS units, DSLR cameras, tablets, laptops, and more. Charging a device with the Sherpa 50 takes the same amount of time to charge as it does from the wall.
  • Dedicated laptop port: A dedicated laptop port with cable and assorted connectors lets you charge your system directly from the Sherpa 50. No need to lug your laptop adapter and cables.
  • Battery capacity: This battery has a capacity of 58Wh (11V, 5,200mAh), offering lots of power for charging a variety of devices. A headlamp uses 4Wh for up to 12 charges; a smartphone uses 5 to 7Wh for up to 7 charges; a GoPro uses 5Wh for up to 9 charges; a digital camera uses 8Wh for up to 5 charges; a tablet uses 25 to 42Wh for 1 to 2 charges; and a laptop uses 50Wh for a single charge.
  • Powering the power pack: Charge the Sherpa 50 in 3 hours using the wall charger or car charger.
  • Store the sun for later: You can also use a Goal Zero solar panel to charge the Sherpa 50, but charging times will vary: Nomad 13, 8 to 16 hours; Nomad 20, 6 to 12 hours; Boulder 15, 8 to 16 hours; and Boulder 30, 4 to 8 hours (each sold separately).
  • Portable design: Compact and weighing only 0.54kg (1.2lb.), the Sherpa 50 can go with you anywhere.
  • Charge in the dark: A built-in LED light on the front makes it easy to charge your devices when it gets dark.
  • More power: The Sherpa 50 can be chained together with another Sherpa 50 power pack (sold separately), allowing your devices to charge faster.
  • Input indicators: Blue light ring on the input port lets you know that you know the Sherpa 50 is getting power, and the LCD display shows the charging status of the battery pack.

    Battery failed 1 year after purchase, goal zero would not replace it per warranty restrictions. It worked marvelously until that point. I wont be another goal zero product again.

  • Sherpa Failed Less Than 18-months After Purchase
    by John in Michigan

    I have purchased multiple Goal Zero products (Yeti 400, 4 Boulder 50s) and this Sherpa 50 in late 2015 / early 2016. I use the Yeti and Boulders on a regular basis for tailgating, camping, etc. These two products work phenomenally and I've never had an issue. However, I've had the Sherpa 50 with inverter since early 2016 and since then the unit has been nothing but problems. Initially I purchased the item to give an additional charge to my MacBook Air and iPhone when I was off the grid. The first time I used it, it only charged the MacBook Air about 1/2 way and I got about 1-2 charges off the unit. Needless to say I was disappointed in the underperforming charge of this product. I would make sure that I properly charged the unit and used the inverter properly. Still, I could not get more of a charge. This past August 2017, I went to use the unit and there was no charge in the unit. After trying to re-charge the unit (which I accomplished two-weeks prior with a full charge), the unit would not hold a charge. Disappointed.

  • Short life

    Sherpa 50 works well in many ways. The huge disadvantage is the swift drop in life/capacity. First it dropped down to charging up to 80%, this spring 2017. After the summer only 40%. I think it ought be more robust in this sense.
