Nitecore NB10000 Gen4 (Gen 4) Ultralight 10000mAh Power Bank Review

A cable that stays with the bank is harder to forget at the previous stop. The Nitecore NB10000 Gen4 (Gen 4) Ultralight 10000mAh Power Bank uses a lanyard-style USB-C cable, combining a carrying detail with the connection needed to make the battery useful.

Small Details Around Daily Carry

Nitecore lists a weight of 4.94 ounces for the 10,000mAh unit. That makes it worth comparing for a small pack, though I'd check how the lanyard cable sits with the rest of the gear. A carrying loop is convenient only when it doesn't snag or put stress on the connection.

• Capacity: 10,000mAh.
• Connections: Two USB-C ports.
• Listed maximum: Up to 22.5W fast charging.
• Protection: IPX7.

Two Ports Need a Shared-Power Check

A phone and another small device can be connected together, but the maximum ratings need to be read with the combined-output rules. I'd confirm the charging protocols and use cables suited to each device.

Pass-through charging is also described. That may simplify a stop with limited outlets, as the bank can replenish while supplying a device under the supported arrangement. It doesn't remove the input source's power limit.

Status Without a Full Display

Illuminated ports and a knock-to-wake function provide a different way to check the battery. I'd want to know how easy those indicators are to interpret in daylight and whether they can be mistaken for more precise measurements than they provide.

The IPX7 rating is useful, but keep the specified wet-use and charging restrictions in mind. A protected enclosure doesn't mean wet connectors should be plugged in casually.

This review is based on manufacturer information. I'd compare Gen4 for someone prioritizing a light 10,000mAh reserve and mostly USB-C equipment. If an older USB-A device is central to the kit, include the appropriate adapter in the comparison.
