Nelko P21 portable Bluetooth label printer
Product description
If you want quick, neat organisation for home, office, or school, the Nelko P21 portable Bluetooth label printer is a handy way to make labels without ink or toner. It pairs with a mobile app over Bluetooth so you can design and print labels from your phone when and where you need them. ✅
Key features
The Nelko Label Maker Machine with Tape, P21 is designed to be compact and easier to carry than traditional label makers, so it suits everyday tasks where a label helps you stay organised. It prints monochrome black text, making it a straightforward option for lists, identification, and storage labels. 📦
Bluetooth printing is handled via the Nelko app, with templates that help you start fast. You can choose from a range of fonts and languages, then build labels with elements like QR code, barcode, materials, images, time, and borders. The printer uses direct thermal technology, so there is no ink cartridge to replace.
It also includes a built-in rechargeable battery, which is useful if you are printing around the house or away from a desktop setup. For printing quality, the manufacturer recommends using Nelko thermal label paper. Note that the monochrome printout only prints black text, and colour labels require colour pattern label tapes.
As a practical detail, label length is fixed, and the feed supports specific sizes such as 12x40mm, 15x30mm, and 15x40mm. You should also avoid tearing or destroying the green sticker on the back of the label strip because it can affect the printing effect. Finally, continuous label tapes are not supported.
Is it a good fit for your workflow, or do you mostly need simple, reliable labels on the go? That depends on whether you can work within the fixed label sizes and app based setup.

Pros
The strongest advantage of the Nelko P21 is its portability, it is built so you can slip it into a pocket and print labels whenever it suits you. Wireless Bluetooth printing removes the need to connect a computer for everyday label making, and that can save time when you are reorganising drawers, cupboards, or shelves. For schools and offices, the monochrome output can be especially useful when legibility matters more than colour.
Another practical win is the app based template system. With more than 90 fonts, 10 plus languages, and 450 plus materials available in the app, you can create labels for many common use cases without starting from scratch. The templates support multiple label styles such as QR codes, barcodes, and bordered designs, which helps for reminders, product or item identification, and storage systems.
It is also designed to avoid ink and toner by using direct thermal printing. That means fewer consumables to manage, although you still need compatible thermal label paper and, for colour label printing, colour pattern label tapes as noted by the manufacturer. 🔍
What’s included
The product listing describes the label maker as a machine with tape, but it does not confirm whether a charging adapter is included. The manufacturer also notes that the charging adapter is not included and that it is not suitable for a fast charging adapter, so it is worth checking what comes in the box when you receive yours. 🧾
For best results, you will also want to use the recommended Nelko thermal label paper to keep printing quality consistent.
Who it’s for
It makes sense if you want phone based label making for household storage, office organisation, classroom identification, or simple mailing and reminder labels. It may not suit you if you need multi colour printing on standard tapes, or if you prefer printing directly from a computer rather than using the Nelko app. It also may not be the best match if you rely on continuous label tapes, because continuous tapes are not supported according to the manufacturer.
If you are using an iOS device, keep in mind the manufacturer note about printing multiple copies. For P21 Nelko APP iOS users, printing multiple copies can be abnormal on iOS V2.7.0, and the manufacturer recommends updating the Nelko APP to the latest version V2.7.1. For Android, it is noted that it is not compatible with Google phones on Android 14.
