Redefining Portability—Egretech Portable Power Station

Why did Egretech choose portable as a market entry point?

As portable energy storage gradually becomes accepted in the market, we have been continuously exploring various application scenarios such as outdoor travel, self-driving camping, power outages, and home backup power. Taking camping as an example, the heavy camping equipment burdens outdoor travel. Saying goodbye to complicated charger accessories, a portable and easy-to-use outdoor power source that supports multiple charging ports can bring consumers a more relaxing outdoor experience.

Through research, we found that in the energy storage market, apart from home use, a large portion of customers consider it a must-have item for travel, RV tourism, and short-term outdoor off-grid experiences. Therefore, customers fantasize about smaller, lighter, and higher-capacity energy storage products.

In our own use, we also believe that portability and easy storage are important factors in real-life scenarios.

What efforts have we made to make it smaller, lighter, and thinner?

After determining our requirements, we extensively explored and attempted to lightweight and miniaturize in the small and medium capacity segments. In the end, we achieved the ultimate utilization of space through various means, resulting in a power density of our product that is over twice as high as unidirectional inverters in the market. Compared to similar capacity competitors, our product is generally 20% lighter and 40% smaller (some models can even achieve 40% lighter and 70% smaller).

The secrets behind this are:

1. The unique topology of a resonant-controlled high-frequency bidirectional inverter that maintains a compact structure while still possessing bidirectional inversion capabilities.

2. Customized special components that enable the semiconductor packaging of the product to become more planar. At the same time, wide bandgap semiconductor components help break through and achieve high-frequency inversion designs.

3. Our research and development team has an average work experience of more than 8 years, with a rich background in automotive power system design, allowing them to optimize space utilization through internal component stacking in limited spaces.

4. The use of automotive-grade VDA battery modules that can adapt to cyclic utilization architecture.

Most products on the market, for example, a 300W product, have dimensions of approximately 11 inches in length, 7-9 inches in width, and 7 inches in height. The weight is usually between 7-10 pounds. On the other hand, Egretech's Plume300W has dimensions of 10.4 inches in length, 9.5 inches in width, and 1.96 inches in height, with a weight of 4.7 pounds, which is half the weight of other brands. This makes it easier to carry and store.

What impact does a more convenient power station have on our lives?

Portable energy storage power supplies can be used as mobile "charging stations" for outdoor activities such as camping and hiking, as well as "emergency power sources" for home power outages and emergency preparedness.

These products fill the gap between power banks and fuel generators and can support short, medium, and long-term power usage based on different capacity models. They offer enduring battery life and also support green power generation.

Taking the outdoor scenario as an example, during outdoor activities such as camping and hiking, running out of power can cause many problems, even if cooking, outdoor movie screenings, and drone photography are reluctantly sacrificed. People still worry about emergency power needs. Unlike power banks, outdoor power sources can meet more of users' electricity needs. They are lighter than fuel generators, can be carried by a single person, are portable, and easy to use (no wiring required). These sustainable power sources for outdoor use enable users to explore more outdoor power scenarios and unlock more activities during their trips.
