Real‑World Performance & Limitations (Based on Teardown / Tests)

While manufacturer claims are useful, independent tests and teardown reviews give insights into actual behavior and limitations. Some of the observed behavior includes:

• The QC 3.0 port is realized via an internal boost converter from 5 V; when multiple ports are under heavy load, the QC port may not maintain its highest voltage/current output. Lygte-info

• The USB standard ports tend to share current; heavy loads may cause voltage drops or interference between outputs. Lygte-info

• The display does not always show actual voltages on non-QC ports — e.g. it may always show ~5.2 V even under varying loads. Lygte-info

• Under full load (e.g. trying to draw near 40 W across ports), the unit becomes warm (measured up to ~80 °C in some internal parts). Lygte-info

• The wireless (Qi) function is weaker and sometimes has difficulty maintaining consistent charging current under load. Lygte-info

• The overload protection seems to kick in around 8.5 A of total current across outputs (which is beyond spec) — when that happens, the unit may stop or flicker. Lygte-info

Overall, the unit performs decently under moderate loads, but pushing all ports near maximum simultaneously reveals limitations in real output stability, heat, and regulation.

Use Cases & Suitability

This kind of charger is best suited for the following scenarios:

• Charging multiple low- to moderate-power devices simultaneously (phones, tablets, cameras, wearables)

• Environments where a single consolidated charger is more convenient than multiple adapters

• Use cases where a somewhat lower priority on ultra-fast charging on all ports is acceptable

• For travel or shared workstations where many devices need charging

However, it may not be ideal if:

• You expect full 3A+ fast charging simultaneously on many devices

• You have devices that demand very tight voltage regulation

• Thermal dissipation is a concern (in hot climates)
