Portable power supplies are not only used for outdoor leisure activities such as camping and sleeping in the car, but in recent years, portable power supplies have become commonplace in every household as a disaster prevention measure. The latest models in 2026 have made remarkable advances, such as increasing the capacity and output of batteries, dramatically improving charging speeds, and using safer and longer-lasting battery materials. This time, we will introduce how to choose and compare the latest portable power supplies.
Currently, the most important keyword when choosing a portable power source is “lithium iron phosphate battery.” Compared to conventional ternary lithium-ion batteries, they are highly safe with extremely low risk of fire, and have an extremely long lifespan of approximately 3,000 charge/discharge cycles (compared to approximately 500 with conventional batteries). It is calculated that it can be used for more than 10 years, so if you are planning to purchase it now, it is no exaggeration to say that the model that uses lithium iron phosphate is the only choice.
As a guideline for capacity, we recommend a middle-class battery with a capacity of 500Wh to 700Wh, which is easy to handle for 1 night or 2 days of camping, sleeping in a car, or short-term power outage measures. It can charge your smartphone dozens of times and keep things like electric blankets and small fans running throughout the night. If you want to perform full-scale disaster prevention or run home appliances with high power consumption such as microwave ovens and hair dryers, you will need a large capacity model of 1000Wh to 1500Wh. However, since it weighs over 10 kg, you will need to be careful when carrying it.
As for manufacturers, three major brands are leading the market: Jackery, EcoFlow, and BLUETTI. For example, EcoFlow’s latest model has overwhelmingly fast charging technology that allows it to be fully charged from an outlet in just over an hour. BLUETTI, on the other hand, has its own strengths, such as being modular and allowing the battery to be expanded later.
Please choose the latest portable power supply that can be used safely for a long time according to your purpose and budget.
