There is nothing as reassuring as having a power bank that can keep your devices up for long hours in the absence of electricity. This reassurance is what the Sherpa 100AC offers. The power bank has an incredible battery capacity for a power bank. It has a 25,600mAh battery which converts to about 94.7Wh.

This means you can use this power bank as a carry-on item for air travels, rather than go with bigger units that won’t be allowed on airplanes (the threshold according to the FAAOpens in a new tab. is 100Wh for carry-on, rechargeable lithium batteries). The Sherpa 100AC comes with multiple ports for charging numerous gadgets at the same time. It also has multiple recharging options, meaning that you are not tied to a single charging method. 

The term “power bank” may be a bit confusing when compared to the Yeti 200X, which is technically a “portable power station” or “solar generator”.

A power bank can be anywhere from 5,000mAh to 30,000mAh or larger in battery capacity. They are typically rectangular in shape and are only used to charge up small devices via USB connections. A solar generator typically has at least a 100Wh battery, but the majority of solar generators range from 500Wh to more than 5,000Wh. These systems can be charged via solar panels and will be able to power several different high-powered appliances and devices.

The Sherpa 100AC powers anything from smartphones to laptops and camera batteries.

In summary, the Sherpa 100AC is a powerful yet lightweight power bank that can keep your devices charged for long periods of time. The Sherpa 100AC is unique because it incorporates a single AC port within its output array. This is a very uncommon feature, as nearly all power banks have only USB or DC-capable outputs.

The most important features of these two systems are their batteries and input/output ports. In that regard, the specifications of both the Sherpa 100AC and Yeti 200X are listed below.

However, the Yeti 200X has a longer cycle life than the Sherpa 100AC with its 500 cycles to 80% capacity.

Yeti 200X vs Sherpa 100AC – Charging Duration and Mechanism

Battery charging icons

Portable power stations and battery banks do not produce electricity. They store the electricity produced from different sources. The process of storing electricity in these systems’ batteries is simply known as charging or recharging. 

From its definition, it is clear that charging is an important feature of both of these products as it affects its ability to adequately power any gadget or device. Therefore, it is important to consider the charging methods available for the power stations under review.

Charging the Yeti 200X

There are three major charging options for the 200X. They include charging from the wall, from solar panels, and from the car. The wall charging method involves the use of a 60W power supply cable, which charges the Yeti 200X in four hours. Should you want to reduce this duration to half, you can use the Yeti X 120W Power SupplyOpens in a new tab.

The solar charging option allows for various sizes of solar panels to be used with the 200X. The capacity of the solar panel(s) determines the charging duration.

For instance, it takes 11-22 hours to fully charge the Yeti 200X when using the Nomad 20 solar panel. The Nomad 50 and Boulder 50 each take about 4-8 hours to charge the power station. The Nomad 100 solar panel takes about 2-4 hours to fully charge the 200X.

Finally, the car charging option involves plugging the power station into the 12V outlet of your car. The cable designated for this purpose is the Yeti Lithium 12V Car Charging CableOpens in a new tab.. The usage of another cable for car charging is dangerous and can damage the solar generator.

Charging the Sherpa 100AC

The Sherpa 100AC equally has the same three charging options: solar, wall, and car charging.

The Goal Zero Sherpa 45W wall chargerOpens in a new tab. completes the recharging process in three hours. The wall charger is not included with the Sherpa 100AC or 100PD power banks. It has a USB-C output (45W max) and a USB-A output (12W max).

The duration for the solar charging options, in this case, also depends on the size of the solar panels. For instance, the Nomad 20 charges the 100AC in 7.5-15 hours. The Nomad 50 and Boulder 50 will take 3-6 hours to charge the Sherpa up.

You can also use the 60W USB-C PD cable to complete the charge in 2.5 hours. However, the use of a USB type-A charging cable extends the charging duration to about nine hours.

Lastly, the car charging option takes three hours to complete the full recharging of the Sherpa.

Verdict – Charging Duration & Mechanism

Both of the products under review have the same charging options. While the Sherpa 100AC charging durations are shorter than that of the Yeti 200X, the longer charging duration of the Yeti 200X can easily be attributed to its higher battery capacity. 

Output Ports – Yeti 200X vs Sherpa 100AC

One of the features of an impressive portable power station or power bank is its ability to charge numerous gadgets simultaneously. The higher the number of ports, the more gadgets you can charge at the same time.
