FAQs
Q1: How many charges can a power bank provide?
It depends on capacity, device battery size, and efficiency. A 20,000 mAh bank might give 4–5 full smartphone charges, depending on energy conversion losses.
Q2: Can I charge the power bank and my phone simultaneously?
Some models support pass‑through charging; check the specific product features.
Q3: Are these safe for air travel?
Yes, as long as the capacity is within airline regulations (usually under 100 Wh). Always check airline policies.
Q4: What’s the difference between PD and QC?
Power Delivery (PD) and Quick Charge (QC) are fast-charging protocols; PD is more universal and modern, QC is common in many devices.
Q5: Do these support USB‑C and USB‑A devices?
Yes—many banks include both output types to cover diverse device types.
Q6: Will the output voltage drop as it's used?
Some voltage drop is natural as battery depletes, but good banks keep output stable until near depletion.
Q7: How many ports can I use simultaneously?
You can use multiple ports, though total wattage is shared among them — performance may reduce if overloaded.
Q8: Does fast charging wear out batteries faster?
Modern devices manage charging curves; occasional fast charging normally doesn’t cause significant battery wear.
Q9: How do I maintain my power bank’s health?
Avoid full discharges, keep in moderate temperature, and cycle usage periodically.
Q10: What’s the warranty or return policy?
Gorilla Cases supports standard returns and warranty on power banks; check individual product pages for details.
