## Before you buy

- The manufacturer states that the four built-in cables and four additional ports can charge up to six devices at once, and that the USB-C and iPhone cables support 20W PD/QC fast charging. Actual charging depends on device compatibility and use. It also advises using low-current mode for headphones and watches, carrying the power bank in hand luggage rather than checked baggage, and stopping use if its temperature exceeds 45°C. The maker says some warmth during charging is normal.
