Frequently Asked Questions
How many ports and watts do I need for a study group?
Count the devices you normally want charging at once. For 4–8 phones, an 8–12 port hub with PD/QC support is fine; for 10–20 devices choose 20+ ports. Also check total wattage: higher total wattage and intelligent power distribution mean devices charge faster when many are plugged in.
Will a multi-port charger slow down my phone if many devices are plugged in?
Not necessarily. Hubs with IC detection or per-port power limits allocate power dynamically so each device gets safe current. However, if total demand exceeds the unit's wattage, charging speeds can drop — choose a higher-wattage hub or add a power bank to avoid throttling.
How can I prevent cable chaos and ownership mix-ups during group sessions?
Use labeled or color-coded cables (small adhesive tags or colored braided cables), supply a central cable basket, and assign each socket or slot a number. Keep extra short, durable cables on hand and consider having one or two power banks for people who need to move around between sessions.
