CBWOIHELP 308 Black Ink Cartridge, 308XL replacement

CBWOIHELP 308 Black Ink Cartridge is a black 308XL replacement cartridge for selected HP DeskJet and Envy printers. Its claimed yield is up to 730 pages at 5% A4 coverage, but the listing conflicts on whether the pack contains black only or black and colour cartridges.

What to know before buying

Listing details to confirm

The listing conflicts on product identity and pack contents: it is titled as a black replacement and highlights one item, yet the explicit box list names both a black and a colour cartridge. It also calls the cartridge both a replacement/remanufactured compatible product and “Genuine”, and its compatibility lists vary. Confirm the selected pack, cartridge type and exact printer model before buying. The 730-page claim is stated at 5% A4 coverage.

Who is it for?

A good fit for

  • Owners of a listed HP DeskJet or Envy model who need a black 308/308XL replacement for everyday documents.
  • Buyers who want a stated page-yield figure and are willing to confirm the exact model and package contents.

Less suited to

  • Anyone who needs a confirmed black-only pack or a confirmed colour cartridge without resolving the listing’s conflicting contents.
  • Printers not identified in the listing’s compatibility information.

Ratings are mostly in the five-star category, with a smaller one-star share, but the available aggregate data does not explain buyers’ experiences or establish how the cartridge performs. It is not enough to confirm the claimed yield, printer recognition or compatibility, so check the product and pack details against your printer needs.

Frequently asked questions

Which printers is this cartridge listed for?

The listing names selected HP DeskJet 2900 and 4300 series and Envy 6100 and 6500 series models, with a shorter model list elsewhere. Check your exact printer model against the full listing before ordering.

How many pages does it claim to print?

The listing claims up to 730 black pages at 5% A4 coverage. Page coverage affects actual yield.

Is this a black-only cartridge pack?

The title and item highlight point to one black cartridge, but the explicit box contents list names one black and one colour cartridge. The actual selected pack is therefore unclear.

Is the cartridge genuine or remanufactured?

The details label it “Genuine”, while a feature describes it as a remanufactured replacement. The listing does not settle the cartridge type.
