FAQ
Frequently Asked Questions
Find quick answers to the most common questions about AISNI products and charging.
Yes. AISNI iPhone chargers are MFi (Made for iPhone/iPad) certified by Apple, which means they meet Apple's strict safety and performance standards. Each charger includes multi-layer protection against over-voltage, over-current, over-temperature, and short-circuit conditions. Your iPhone and its battery are in safe hands.
AISNI 20W chargers are approximately 3× faster than standard 5W adapters. Our 45W GaN chargers for Samsung can charge a Galaxy S24 from 0 to 57% in approximately 30 minutes — a full charge in under 90 minutes. The exact speed depends on your device model and its supported charging protocols.
Our 20W USB-C chargers are compatible with iPhone 15, 16, and 17 series, iPad Pro, iPad Air, and any USB-C device up to 20W. The MFi 2-Pack also works perfectly with iPhone 11, 12, 13, and 14 series. The 45W GaN charger is optimized for Samsung Galaxy S-series (S23/S24/S25/S26) and supports any USB-C device up to 45W — including laptops.
GaN (Gallium Nitride) is a semiconductor material more efficient than traditional silicon used in older chargers. GaN chargers run significantly cooler, waste less energy as heat, and can deliver more power from a smaller, lighter package. In practical terms: a 45W GaN charger can be barely larger than a standard phone charger, while outputting enough power to fast-charge a laptop.
Yes. AISNI Technology LLC is headquartered in San Jose, California. Our customer support team is available Monday through Friday, 9AM to 6PM PST. You can reach us at [email protected] and expect a response within 24 business hours. We are committed to resolving every issue quickly and professionally.
AISNI cables are engineered to withstand over 10,000 bend cycles — equivalent to years of daily use. We use premium materials and reinforced strain relief at both connector ends to prevent the fraying that makes cheap cables fail within weeks. Our cables are built to match the lifespan of your devices.
Every AISNI charger includes the charging cable — no hidden additional purchases needed. The 3-Pack includes 3 charger blocks + 3 USB-C cables (6FT each). The MFi 2-Pack includes 2 charger blocks + 2 USB-C cables (10FT each). The Samsung 45W 2-Pack includes 2 charger blocks + 2 USB-C cables (6FT each). Everything you need is in the box.
Yes, completely safely. Your iPhone has built-in charging circuits that regulate exactly how much power it draws. When connected to a 45W charger, your iPhone will automatically negotiate via USB-C Power Delivery to draw only the wattage it's designed to accept (20W for modern iPhones). The higher capacity of the 45W charger simply means it can handle the load without getting warm, while also being able to simultaneously charge a laptop or tablet.
