Devices charge slowly or are not full in the morning

Many devices at once: The charging electronics share the power between all devices. During the day charging takes longer; overnight there is normally enough time.
USB or USB-C PD: Models with USB-C PD charge faster than models with USB-A. Your version is shown on the product page and in the data sheet.
Cables: Use cables that support fast charging. Damaged or very long cables charge more slowly.
Devices in use: Updates or running apps slow down charging. Charge them in sleep mode.
Heat: Tablets charge more slowly when they are warm. Keep the ventilation openings free.
Power at night: Check whether the socket is switched off at night (timer, building control).
