I bought the Snug Lite 1-Port Home Charger with Type-C Cable (2.1A) in January 2026. The delivery was fast, and the charger is still working perfectly.

If the product is imported, delivery may take longer. However, if it’s a local product, delivery is usually much faster. I'm happy with their service.
