BatteryRank review
A slim, 10,000mAh-class outdoor option for buyers who value a 155g listed weight and water-resistance rating over a higher USB-C output ceiling.
Ratings below are manufacturer-claimed. Open a reading to see its source and check date; derived comparisons are identified separately.
Use and carrying fit
Nitecore lists the NB Plus at 122.4 × 59.6 × 11.7mm, 155g ±5g, and IPX7. Its USB-C output reaches 22.5W, while a USB-A port is available for a second cable type; the maximum total output is lower when ports are shared.
What changes the choice
Although both USB-C and USB-A are listed at 22.5W individually, Nitecore gives a 15W total-output maximum. Connecting another device changes the available power budget.
Nitecore specifies 155g ±5g with accessories excluded. A carrying comparison that includes a cable or other add-ons should count those separately.
Before connecting devices
A port’s published maximum and the combined multi-port limit are separate ratings. A device can draw less than the bank’s maximum based on its own requirements and the negotiated charging profile.
Nitecore lists USB-C input at 18W maximum and USB-C output at 22.5W maximum. Refill and device-charging rates are separate limits; compatible adapters, cables, and device profiles determine the negotiated rate.
Manufacturer documentation
Manufacturer claims link to the dated source used for this exact revision. Watt-hours appear only when the OEM states them explicitly; we do not infer energy from milliamp-hours.
Exact-model questions
No. Nitecore lists 22.5W maximum for the individual USB-C and USB-A outputs, with a separate combined total-output limit of 15W.
Nitecore specifies 10,000mAh at 3.85V, or 38.5Wh, and separately lists 5,600mAh at 5V as rated output energy. We use 38.5Wh when comparing rated battery energy per gram.
