To help you decide, I tested the efficiency, in a variety of scenarios, of the best portable power stations from Jackery, Oupes, EcoFlow, Anker, Goal Zero, Grecell, Bluetti, Dakota Lithium, Lion Energy, Vtoman, and Ugreen. What to Know Before Purchasing a Portable Power Station [pdf]
These applications are differentiated by two main categories: those that require large amounts of energy in the long term, and those that require high power, i.e., high rates of energy transfer. [pdf]
[FAQS about What are the two major categories of energy storage power supplies ]
The current relevant standard for power supplies is EN61204-3: 2000. This covers the EMC requirements for power supply units with DC output (s) of up to 200V, at power levels up to 30kW, and operating from AC or DC source voltages of up to 600V. The "EN" refers to Euro Norm or European standard. [pdf]
