Quick Summary
The Nelko P21 is a portable Bluetooth label maker in white for printing labels to help with organising storage, office items, home items and more. It uses direct thermal printing and is stated as monochrome, so it prints black text only.
The compact format is described as half the weight and size of a traditional label maker, and it is designed to work with the Nelko app on iOS and Android phones via Bluetooth.
Who It Is Best For
This label maker suits buyers who want a small, wireless printer for everyday labelling on a phone. It is aimed at organising clothes, food storage, cosmetics, mailings, notebooks, price tags, reminder tags, classroom items and personal items.
It is also worth checking app compatibility before ordering, especially if you use Android 14 or plan to use a computer, because the unit is stated as not working with computers.

What To Know Before You Buy
Confirm that you plan to print from a phone, because the unit is stated as not working with computers. Check your Android version if relevant, as Android 14 compatibility is specifically flagged in the description. The printer is monochrome, so it prints black text only, and continuous label tapes are not supported.
Use the stated label types and keep the green sticker on the back of the label strip intact to avoid affecting print quality. A charging adapter is not included, and the product should not be used with a fast charging adapter.
