NELKO P21 vs Brother PT-D220: Choose Your Label-Making Routine

Choose the NELKO P21 if you want to compose labels in a compatible phone app and recharge the printer. Choose the Brother PT-D220 if you want to type directly on a built-in keyboard without using a phone; you must supply its batteries or optional AC adapter. The choice is how you create labels and replenish power, not a proven difference in print quality.

The buying question

Do you want to design labels on your phone and recharge the printer, or type on the label maker and supply batteries or an AC adapter?

The P21 combines phone-app composition with rechargeable power; the PT-D220 provides a self-contained keyboard workflow but needs separately supplied power.

Quick verdict

Choose NELKO P21 if

  • Your phone is compatible with the NELKO app and you prefer designing labels there.
  • You would rather recharge the printer than keep AAA cells on hand.

Choose Brother P-touch PT-D220 if

When the recommendation changes
  • If the intended phone is incompatible, the P21 loses its workflow advantage; verify the exact phone, OS and app before buying.
  • If replacing AAA cells is unwelcome, favor the P21 recharge routine or include the PT-D220 adapter in your desk setup.

The differences that matter

Label Input Workflow

NELKO P21

Compose labels in the NELKO phone app and connect by Bluetooth. The P21 is intended for mobile printing, not computer printing.[1, 2]

Brother P-touch PT-D220

Type on a built-in QWERTY keyboard and preview on the device display; Brother specifies no mobile-device printing app.[3]

What this changes: Choose the P21 if phone-based composition suits you and your phone is compatible. Choose the PT-D220 when you want to make a label without involving a phone.[1, 2, 3]

The better fit depends on your priorities

Power Replenishment

NELKO P21

Rechargeable battery with Type-C charging.[1]

Brother P-touch PT-D220

Six AAA batteries or an optional AC adapter; neither is included.[3]

What this changes: For a bag or drawer, choose whether you would rather recharge the P21 or keep AAA cells available for the PT-D220. For a fixed desk, the PT-D220 offers optional mains power, but budget for the adapter.[1, 3]

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Compare the current offers after allowing for the power accessories you need. A higher price is justified only if that model matches the way you will actually create and power labels.

There is not enough verified price history here to recommend buying now or waiting.

Limitations

  • The selected P21 retail listing warns that it is not compatible with Google Pixel phones running Android 14 and does not work with computers. The manufacturer also describes a mobile-only workflow. Check current compatibility for your exact phone and app version before purchase.
  • NELKO support says the P21 supports continuous labels, while the selected retail listing says labels are fixed-length and continuous tape is unsupported. This conflict is unresolved for the selected unit; confirm the exact printer revision and compatible roll before ordering refills.
  • The selected P21 retail listing excludes a charging adapter. Brother excludes both the six AAA batteries and optional AC adapter from the PT-D220 package. Do not treat the PT-D220 adapter as evidence of in-device battery charging.
  • No hands-on or controlled comparative testing supports a print-quality, adhesion, battery-runtime, speed or reliability winner.

Questions shoppers ask

Can the P21 replace a computer-connected label printer?

No. NELKO describes the P21 as a mobile printer using its phone app and directs computer-printing buyers to other models. A phone app is part of this purchase, not an optional replacement for desktop software.

What should I check before ordering replacement labels?

For the P21, confirm the exact roll and printer revision: NELKO support describes continuous labels, but the selected retail listing says fixed-length labels only. That disagreement is unresolved. The PT-D220 uses the Brother TZe tape family; choose a compatible tape for the surface and job.

What needs to be added to the box for power?

The P21 selected retail listing says a charging adapter is not included. For the PT-D220, Brother says both the six AAA batteries and the optional AC adapter are sold separately. Include your preferred power source when comparing checkout totals.
