Price & Value: KNAON is more expensive, but offers broader functionality

The KNAON Bluetooth Thermal Shipping Label Printer costs $49.49, nearly double the $23.26 price of the Nelko P21. This represents a 53% price difference, making the Nelko significantly more affordable upfront. However, the KNAON’s higher cost reflects its expanded capabilities, including support for multiple thermal paper sizes and compatibility with major e-commerce platforms like Etsy, Shopify, and USPS. The Nelko, while budget-friendly, is limited to fixed-length label tapes and lacks integration with online shipping systems. For users prioritizing cost savings and simple labeling tasks, the Nelko delivers strong value. But for small businesses needing scalable, multi-platform printing, the KNAON justifies its premium with greater versatility.

Connectivity: KNAON supports multiple devices; Nelko is phone-only

The KNAON printer connects via Bluetooth and USB, enabling use with iOS, Android, Windows, Mac (including M1/M2/M3/M4), ChromeOS, and Linux. It requires the FlashLabel Pro app for mobile devices and specific drivers for computers. In contrast, the Nelko P21 only connects via Bluetooth to iOS and Android phones through its dedicated app—no computer compatibility at all. This makes the KNAON far more flexible for users working across different operating systems or needing desktop integration. The Nelko’s limitation to mobile-only connectivity restricts its utility in office or multi-device environments, despite its compact design.

Printing Flexibility: KNAON handles varied label sizes; Nelko uses fixed-length tapes

KNAON supports various thermal paper sizes, allowing users to print labels of different dimensions for diverse applications such as shipping, barcode, mailing, and name tags. This adaptability suits both professional and personal needs. The Nelko P21, however, prints only on fixed-length label tapes—specifically 14×40mm, 14×50mm, and 14×75mm—with no option for custom sizing. Additionally, it does not support continuous label tapes. While this ensures consistent results for standard stickers, it limits customization and scalability. For users who need flexibility in label dimensions, especially for business logistics, the KNAON’s variable size support provides a clear advantage.

App Features & Templates: KNAON offers more extensive content and tools

The KNAON’s FlashLabel Pro app includes over 3,000 templates, 5,000 icons, and 100+ fonts, supporting advanced features like PDF import from shipping platforms. This enables seamless integration with services like Amazon, eBay, and DHL. The Nelko app, while robust with 750+ templates, 5,500+ materials, 700+ borders, and 3,600+ icons, focuses on quick, pre-designed label creation without PDF handling. It also supports QR codes, barcodes, and images but lacks direct integration with e-commerce platforms. The KNAON’s app is designed for workflow efficiency across multiple platforms, whereas the Nelko excels in simplicity and speed for basic labeling tasks.

Portability: Both are compact, but Nelko is lighter and smaller

Both printers are portable, but the Nelko P21 is explicitly described as half the weight and size of traditional label makers, making it ultra-portable and pocket-sized. The KNAON measures 7.17 x 3.9 x 3.43 inches, which is compact but larger than the Nelko. While both fit easily in a bag, the Nelko’s reduced size and weight make it ideal for users who prioritize mobility above all else. The KNAON’s slightly bulkier form factor is justified by its broader feature set, but for on-the-go labeling without compromise, the Nelko wins on physical portability.

Battery & Power: Nelko has built-in rechargeable battery; KNAON relies on external power

The Nelko P21 features a long-lasting built-in rechargeable battery, enabling extended wireless use without needing a constant power source. No charging adapter is included, though. The KNAON, meanwhile, does not mention a built-in battery and instead supports USB connectivity, implying it must be plugged in during operation. This makes the KNAON less suitable for truly mobile printing scenarios where access to power is limited. For users who need uninterrupted printing away from outlets, the Nelko’s battery-powered design offers a significant practical benefit.

Which should you buy?

Choose the Nelko Label Maker Machine with Tape if you want a low-cost, ultra-portable solution for quick, everyday labeling at home, school, or in the office. At $23.26, it’s about 53% cheaper than the KNAON, and its compact size and built-in battery make it ideal for on-the-go use. Its app offers rich templates and creative tools, though it lacks computer compatibility and platform integration. Opt for the KNAON Bluetooth Thermal Shipping Label Printer if you run a small business requiring reliable, multi-platform label printing. At $49.49, it’s more expensive but supports USB and Bluetooth across iOS, Android, Windows, and Mac, integrates with Etsy, Shopify, USPS, and more, and handles various label sizes. Its ability to import PDF shipping labels directly into the app streamlines workflows. If your priority is versatility and scalability, the KNAON is worth the investment.
