The ACEFAST M14 is a high-capacity 20,000mAh power bank built for fast, convenient charging. It delivers up to 22.5W from either the USB-C (port or built-in cable) or USB-A port, supports the latest standards (PD3.0/PPS/QC4+ and more), and shows exact battery percentage on a LED digital display. You can recharge it quickly via 18W USB-C input, and even use pass-through charging to power your phone while the bank tops up. Durable flame-retardant PC housing and multi-protection electronics make it a reliable everyday backup for Android and iPhone users in Bangladesh.
