EnergyCell Portable Charger & Wireless Charger
Why does my power bank deliver less capacity than expected?
Actual usable capacity is affected by cell conversion losses, circuit efficiency, cable loss, ambient temperature, usage habits, and battery aging. Typically, 60-70% of the nominal capacity is normal.
Can the power bank operate in high-temperature environments?
We recommend using the power bank within 0°C to 40°C (32°F to 104°F). Extreme temperatures may affect battery performance and safety.
Can I bring the power bank on a plane?
Yes. With a capacity of 44.4Wh, this power bank complies with the International Air Transport Association (IATA) regulation (=99Wh).
Is it compatible with iPhone 15 and 16 series?
Yes, it is compatible with both series. However, you'll need to purchase an additional USB-C cable separately. The cable included with the product is designed for charging the power bank itself and is incompatible with iPhone 15 and 16 series.
Is the power bank made of safe materials?
Our power bank uses high-quality materials, undergoes rigorous safety testing, and holds RoHS, CE, and FCC certifications, meeting international safety standards.
