Goal Zero  Sherpa 100AC Power Bank

Now, admittedly an OCD person when it comes to "backups" of every type, I have many different "power banks" and solar panels...Although mostly Goal Zero. My place looks like a Goal Zero showroom. I tested the DJI Phantom 4 Pro drone battery against two other types of, supposedly higher capacity, power banks: The "Suaoki S270 Portable Power Station 150Wh Quiet Gas Free Camping Generator QC3.0 UPS Lithium Power Supply", rated at 150Wh and "max 100W, peak power 150W". After a few minutes of charging the DJI drone battery, the Suaoki Shut down completely. I restarted the S270 and again, after a few minutes, it shut down completely. While the S270 has several 12V, USB and 2 110V AC outlets, it does not have a Qi 5W wireless charger like the Sherpa 110AC does, not is it as compact as the Sherpa 110AC or have an informative display like the Sherpa 110AC does. Next, I tested it against a iPrigent "Portable Solar Generator Power Source - 41600mAh 154Wh" which claims to have a 120 Watt inverter output. When I attempted to charger the DJI Phantom 4 Pro battery, it shut down in less than a minute. The iPrigent has a single 110 v output port/receptacle and two USB ports. The input port is a DC 19 volt, 2 Amp socket that charges the unit from an AC-adapter or solar panel. It lacks any "informative display" and simply states it remaining capacity with a series of 4 tiny blue LEDs. Now back to the Goal Zero Sherpa 100AC: It is compact and high quality throughout. For input (recharging it) it has a standard 8mm Goal Zero input receptacle and two Type C connectors, each rated at 60 Watts each. The Type C connector is 2 way so it can be used for input (recharging) and output (charging something else). It can be recharged with a 12v car adapter as well. The Sherpa 100AC has 2 USB ports rated at 2.4 Ams each, and 1 110 volt AC receptacle . It has a wireless Qi 5 Watt charging pad for phones that have Qi compatible wireless charging, as with the latest iPhones and many Android devices and tablets. I used the Sherpa 100AC to wireless-charge my nearly dead iPhone X, which took between 2 and 3 hours and only consumed 22% of the Sherpa 100AC's capacity. I'm a photographer, using drones, Matterport Systems and conventional still and video equipment. I almost "live" on battery and solar power. The Sherpa 100AC is now my favorite all-around device when I need its capacity. For higher capacity demands I rely on the Goal Zero Yeti 400 Lithium and Yeti 1400 Lithium. In my opinion, the Goal Zero Nomad 28 Plus is the most convenient way to charge the Sherpa 100AC when sun is available. When you want remote or backup power, "usually reliable" is not an option. As a matter of fact, I consider "usually reliable" an oxymoron. I have found this Sherpa 100AC to be "reliable" as in "completely reliable", which is what you want. If you're considering a Power Bank of this capacity, look no further and get the Goal Zero Sherpa 100AC. I doubt that you'd have any second-thoughts!

I don't know why R.E.I./Goal Zero is selling a 25,000 m A h battery with NO 120 VOLT AC CHARGER!!!! UNLESS YOU HAVE A SPARE PHONE CHARGER LAYING AROUND, GOOD LUCK :) If you want to charge this thing, you need to use your existing Cell Phone charger (what a nice touch for a $250 battery, huh?), or buy their solar panels. Both options will take you at least a full day (two days by sunlight, assuming no clouds and optimal panel placement) to charge this unit. IF R.E.I. would simply stock the 120 Volt AC charger, not only would they get the $30 up sell, you'd be able to charge this to 100% in around 3-5 hours. If you ask an R.E.I. associate about this AC charger, they will look at you as if you've lost your mind. "Who would want to charge this thing in a few hours when you can use solar panels and wait a few days?" It has great options, including pass through charging which is important (you can charge the battery while charging other devices). But the fact that R.E.I. is selling this unit without the AC chargers to go with them means a one star rating today. Work on it. Both R.E.I. and Goal Zero. You know better than to sell a product without the accessories that go with it.
