There’s nothing on the market like the Omni 20 USB-C, a sturdy and well-designed charging pack that has a 73 watt-hour (Wh)/20100 millampere-hour (mAh) capacity. Unfortunately, its particular set of features mean it works best for a specific set of users instead of most laptop owners with USB-C charging ports.
Its feature list is quite long. The Omni 20 has two USB-C and two USB Type-A ports. It can output 100 watts total from its two USB-C ports simultaneously (max 60W from each one) via Power Delivery (PD) 2.0 support, and recharge its internal batteries at a maximum of 45W total from either port or both ports at once. It also can push up to 15W from both its Type-A ports and at the same time.
That high rate of output from USB-C means it can keep most MacBook Pro models (except the highest-end model) always charging at full speed while they’re in use, as if they were plugged into AC power. And being able to charge two laptops at once at nearly full-speed rates is a bonus not found elsewhere.
