FAQs

Tempered Glass Phone Screen Protector

1.Is higher hardness always better for a tempered glass screen protector?

A:Not exactly. The common "9H" hardness refers to the pencil hardness test standard, not the absolute hardness of the glass. Glass that is too hard tends to be more brittle and less impact-resistant.
High-quality screen protectors strike a balance between hardness, toughness and shatter resistance.

 

2.What's the difference between 2.5D and 3D product?

A:2.5D film is chamfered on the front side, with a small curve that is not smooth enough. There is a gap at the edge, so dust will accumulate. 3D film uses screen 1:1 size full-coverage glass with a rounder edge curve, which holds the screen firmly. Compared with 2.5D film, it attaches seamlessly and has a smooth touch at the edge. It features a dust-proof design, as if it is a part of the original phone.

 

3.Why do white edges appear on screen protectors?

A:White edges are mainly caused by curvature mismatch or fitting gaps, common in low-quality or non-full-screen protectors.
High-quality 3D curved protectors and precise fitting can avoid this issue.

 

4.Do you support OEM / ODM customization?

A:Yes. We support customization on size, thickness, material, privacy / matte / blue light functions, as well as packaging, logo and manual. Full test reports are provided.

 

5.What is the lead time and after-sales policy?

A:Regular inventory: 2–5 days. Custom orders: 7–15 days. 100% inspection before shipment. For quality issues, we provide 1:1 replacement service.

 

6.How long does a screen protector last?

A:It can be used for 6–12 months under normal conditions. Replace it when scratches, smudge issues, or edge damage appear.

 

7.How to choose between matte and clear?

A:Clear film is for daily use and high definition. Matte film is for gamers, fingerprint resistant and anti-glare, but slightly less clear.

Power Bank and Wireless Chargers

1.What does the rated capacity mean? How many charges can I get?
A: The labeled capacity is the total cell capacity. Due to conversion loss, circuit consumption, and voltage conversion, the actual usable output capacity is standard for the industry. It can fully charge most smartphones 2–4 times, depending on your device battery size.

2.Why does the power bank get slightly warm during charging?
A: Mild heat generation during fast charging or simultaneous dual-device charging is normal and safe. The built-in temperature control system will automatically adjust power output to prevent overheating and ensure stable performance.

 

3.Is this power bank safe for daily use?
A: Absolutely safe. Equipped with multi-layer smart protection systems, including over-charge protection, over-discharge protection, over-current protection, over-voltage protection, short-circuit protection, and temperature protection. It effectively avoids safety risks and protects your devices and the power bank itself.

 

4.Will it damage my phone battery?
A: No. The power bank features intelligent current matching and stable voltage output. It automatically adapts to your device's optimal charging current, preventing overcharging and battery damage, providing gentle and safe charging protection.
