Also, your laptop computer gets 31 full recharges from the power station. Regarding powerful appliance, you can run a 42-inch LED TV for 14 hours and a full-sized refrigerator for 28 hours straight.

Verdict: It is clear and without any doubt that the Yeti 1500X has a better output capacity when compared to that of the Yeti 1400. The reason for this is the fact that the Yeti 1500X battery supplies higher electricity than Yeti 1400.

Size and Portability

The size of a solar generator matters a lot. It determines how well you can carry and handle them, especially when using them for camping or other outdoor activities. Imagine going hiking with a solar generator that’s very heavy.

The Yeti 1400 weighs about 44lbs, which measures as 20kg. While that is a sizable weight, it can still be easily carried short distances. It also comes with two handle straps, which rest atop the power station. These handles make it a bit easier to carry the power station around.

As stated by its manufacturer, the weight of the Yeti 1500X, Goal Zero, is 45.67lbs, which measures as 20.7 kg. Similar to the Yeti 1400, the power station comes with straps for handling and carriage.

Verdict: The weight difference between the two power stations is almost negligible, as they measure almost the same weight.

Battery Type

The type of battery running in a power station influences its efficiency and output. This is why most users consider power stations using lithium-ion batteries as superior to those using lead-acid batteries.

The Yeti 1400 uses a lithium-ion battery. There are three battery cells in the power station, each with a single cell capacity of 140Ah at 3.6V. The total pack capacity is 421Ah at 10.8V. Also, the battery has a lifecycle of 500 cycles with an 80% capacity. The shelf life of the battery pack ranges from 3 to 6 months. The battery gets protection from overcharging and related damages through features like low battery protection and a PWM charge controller.

On the other hand, the Yeti 1500X also uses the same type of battery as the Yeti 1400. In fact, the similarities between their batteries continue to the single-cell and total pack capacity and lifecycles. The Yeti 1500X also mimics the lifecycle and discharge capacity of the Yeti 1400.

This is not very surprising, seeing as the two power stations are products of the same manufacturer. The only difference is that the yeti 1500X is protected by MPPT charging technology rather than PWM as used by the Yeti 1400.

Verdict: As with the size and weight feature, there are barely any differences between the batteries in these power stations.

Charging Mechanism and Duration

Solar power stations do not produce electricity by themselves; they require a means of charging and replenishing the electrical energy stored in their batteries. This is why considering the charging system and the duration of a power station is important.

For the Yeti 1400, there are three methods of charging. These methods include charging via a solar panel, AC electricity, and car battery using a 12V port. The solar panel charging method requires the use of a solar panel, and the charging duration depends on the solar panel capacity in use.

The maximum combination of two Boulder 200 Briefcase solar panels to charge the power station will take 5 to 10 hours. Using the AC electricity through a wall charger rated 5A, you will need to wait 25 hours to get a fully-charged power station. Most importantly, the Yeti 1400 uses a PWM charging technology to protect and enhance this power station’s charging system.

It should not surprise you again that the Yeti 1500X shares the same charging methods as its predecessor. However, there are slight differences when it comes to the charging duration. As the Yeti 1500X has an MPPT charge controller, its charging time is slightly faster than that of the Yeti 1400 power station.

The Yeti 1500X power station takes about 4-8 hours to charge when connected to two Boulder 200 Briefcase panels. And, since the 1500X allows for up to 600W of solar input, you can use three Boulder 200 solar panels to charge the battery in 3-6 hours! This improvement in solar input capability brings a much faster charge to the 1500X when using its maximum solar input. The duration for AC/wall charging depends on the capacity of the wall charger.

A wall charger rated 120W charges the solar power station for 14 hours while a charger rated 230W charges for 7 hours.

Verdict: Both power stations use the same charging methods, but the Yeti 1500X, although having a larger battery capacity than the 1400, charges at a faster rate because of its MPPT charge controller and up to 600W of solar input. The Yeti 1400 Lithium charges slower than the Yeti 1500X due to its PWM charge controller and 360W maximum of solar input.

Durability and Warranty

For most parts, solar power stations are used outdoors, where they get exposed to weather elements. Thus, solar generators must be durable and rugged.

When discussing power stations’ durability, a vital point to consider is the lifecycle of the generator’s battery. A single lifecycle is the time taken to fully drain the battery before recharging. The Yeti 1400 has 500 cycles, which implies that the battery can last for well over a year if the battery is used from full capacity to zero every day. Comparatively, the Yeti 1500X also has the same lifecycle.

Another point that we should consider is the warranty period given on the products. And as with the lifecycles, both products have the same warranty period of 24 months.

Verdict: Both power stations are equally durable if the battery’s lifecycles and product’s warranty period is important to you.


Inverters help power stations work more efficiently and last longer. The Yeti 1400 uses a 1500W continuous inverter with a peak capacity of 3000W. This inverter ensures that the solar power station can power appliances that draw about 1500W of electrical power for some time without any issue.

As stated earlier, the Yeti 1500X has a larger inverter and battery capacity as the Yeti 1400 power station. It also possesses advanced surge management that shuts the inverter down if you run appliances drawing over 1500W for a long period.

Verdict: The Yeti 1500X has a larger inverter (2000W continuous, 3500W surge) than the Yeti 1400 Lithium (1500W continuous, 3000W surge). This makes the Yeti 1500X a great option if you intend to use it for larger appliances.

RV Connectivity

The beauty of a portable power station is the ability to use it for outdoor activities and RV camping. However, none of the two power stations under review have a designated RV connection point. However, a 12V charging port allows you to connect the power station to an RV input.

Verdict: Both power stations do not have inbuilt RV connectivity capacity.

Number of Ports

Having multiple ports on the body of a power station increases its usability. It means that you can connect numerous devices and appliances to the power station at the same time.

The Yeti 1400 features ten different ports for various uses. These ports include 3 USB ports (one type A, one type C, and a PD port), two charging ports (one for power pole and another normal 18mm charging port), and many others. The Yeti 1500X shares the same number and types of ports as its predecessor.

Verdict: There are no differences between the number and types of ports available on both power stations.


The cost of purchase is one of the essential factors to consider when comparing two or more power stations. Apart from affecting your finances, it helps you understand if the purchase is a good economic decision by comparing the power station’s features and benefits to its cost.

The price tag on the Yeti 1400 is $1899.95, according to Goal Zero.
