Powershred 79Ci

This is the one category that explains the 79Ci’s whole position in our rankings. It is rated P-4 under DIN 66399 — the same security level as the top-ranked Powershred LX210 — but it reaches that level with a cross-cut, producing 5/32″ × 1½″ strips, roughly 397 particles per letter page. The micro-cut machines above it cut to the same width but a fraction of the length, turning the same page into well over 1,200 particles. Both clear the P-4 bar by particle area; the micro-cut clears it with far more margin.

For the documents a home office actually destroys — statements, tax forms, anything with an account number — P-4 cross-cut is genuinely sufficient. Reassembling 397 pieces is not a task any realistic household adversary will attempt. But “sufficient” is exactly why this scores 8.0 rather than the 9.0 the micro-cut Fellowes earn. Security carries the heaviest weight in our framework (25%) because it’s the reason you own a shredder at all, and a cross-cut simply leaves larger pieces than a micro-cut. The score reflects that gap honestly — not a flaw in the machine.

The takeaway isn’t that the 79Ci is insecure; it’s that it spends its strengths elsewhere. If maximum particle destruction is your priority, its own micro-cut sibling is the better answer. If P-4 cross-cut clears your bar — and for most home paperwork it does — then the 79Ci’s other qualities are what should decide the purchase.

Bottom line on security: Genuine P-4, but via cross-cut — larger strips than micro-cut, sufficient for home documents and the sole reason it scores 8.0. Want the finest particles? The micro-cut LX210 has the identical Fellowes tech.

This is the 79Ci’s standout, and the reason it earns a podium-caliber score in the category that matters most for whether a shredder stays in use. It runs Fellowes’ 100% Jam Proof system — the same active, thickness-sensing technology found on our #1 and #2 machines. Rather than reacting after a jam starts, it measures sheet thickness as paper enters and stops an over-stuffed pass before it binds, lighting an indicator so you can thin the stack and continue. That’s a genuinely better ownership experience than the auto-reverse every non-Fellowes machine in our lineup relies on, which only clears jams after they’ve already happened.

The hardware confidence is unusually strong here: a 2-year machine warranty and a lifetime warranty on the cutting cylinders — the longest cutter coverage of any machine we scored, and a meaningful signal given the cutters are the part that actually wears. Combined with Fellowes’ long track record and the 79Ci’s years of consistent owner feedback as a commercial-grade workhorse, that places it among the most dependable machines in the lineup, just behind the current LX-series flagships.

One ownership note applies to any cross-cut machine, the 79Ci included: the cutters benefit from periodic oiling to hold rated capacity. A lubricant sheet (or a bead of shredder oil on a sheet of paper) every bin-empty or two keeps it cutting at a full 16 sheets; skipping it is the most common reason a shredder seems to “lose” capacity within a year. It’s the cheapest reliability insurance a shredder can get.

Bottom line on reliability: Active 100% Jam Proof prevention plus a lifetime cutter warranty make this one of the most dependable machines we scored — the same jam tech as our #1, in a long-proven commercial design.

On paper the 79Ci matches our #1 pick: 16 sheets per pass, a 20-minute continuous run time, and a 6-gallon pull-out bin. Sixteen sheets handles a folded stack of mail or a stapled multi-page statement in one feed, and 20 minutes of continuous running is enough to work through a real pile — a desk drawer of old paperwork — in a single sitting rather than in stop-start bursts. As a manual workhorse, it’s well-specified.

It scores a notch below the micro-cut LX210 here despite the identical sheet, run-time, and bin numbers, and the reason is a direct consequence of the cut. Cross-cut strips pack less densely than micro-cut particles, so the 79Ci’s 6-gallon bin holds fewer shredded pages between empties than the same-size bin on a micro-cut machine — by a wide margin, a micro bin can hold roughly twice the pages. The nominal capacity is the same; the practical capacity between trips to the trash is lower, and the 8.0 reflects that real-world difference rather than the spec sheet alone.

The 79Ci is manual-feed, the right architecture for steady mail-pile duty plus periodic purges. If your job is destroying years of stored files in batches, the auto-feed AutoMax 150C (150-sheet tray) — which ties this machine’s overall score — is the better tool for unattended volume. For everything else, manual feeding is simpler and more durable.

Bottom line on capacity: Strong manual specs (16 sheets, 20 minutes), but cross-cut’s looser bin packing means fewer pages per empty than a micro machine — the reason it scores 8.0 rather than its micro sibling’s 9.0.

Value is the 79Ci’s one amber category, and the reasoning is precise. It carries a full Fellowes premium for its technology package — and that’s fair, because the Jam Proof and SafeSense systems are genuinely the best in the category. The tension is internal: the micro-cut LX210 delivers the identical technology with a finer, more secure cut, and the two often sell at comparable prices. When that’s the case, you’d take the micro-cut machine and the 79Ci becomes hard to justify on value alone.

Where the 79Ci does earn its keep is versatility and the specific buyer. Beyond paper it shreds credit cards, CDs, staples, and paper clips, so the awkward items don’t need special handling, and the lifetime cutter warranty is a real long-term asset. The value case turns on two things: whether you specifically prefer cross-cut, and whether the 79Ci is priced below the LX210 at the moment you buy. If it is — and as a long-running model it frequently is discounted — the full Fellowes tech at a lower price is a strong deal. If it isn’t, the LX210 is the better spend. That conditional is exactly what a 7.0 captures.

Bottom line on value: The same top-tier Fellowes tech as our #1, but in a cross-cut body. A good buy when it’s priced below the micro-cut LX210; otherwise the LX210 wins on the cut for similar money.

A shredder is the one office machine with a genuine injury surface, and the 79Ci carries the best safety feature in the category: Fellowes’ SafeSense technology. An electronic sensor around the paper opening shuts the cutters down the instant fingers — or a curious pet — touch the feed slot, not merely when something is physically jammed in it. Most machines rely on a narrow slot and an auto-stop switch, which is adequate but not equivalent to active touch sensing. Notably, this is a feature the otherwise-capable AutoMax 150C it ties with does not have.

For a household with young children or pets, SafeSense is the feature that justifies a Fellowes on its own, and it earns the 79Ci a strong 8.5 in a category we weight at 10% specifically for family environments. The machine also includes the conventional protections — an overheat shutoff tied to the 20-minute duty cycle, and auto-reverse to back paper out of the slot.

Bottom line on safety: SafeSense touch-sensing shutoff is the safest implementation in our lineup and a clear advantage for homes with kids or pets — and a feature the tied AutoMax 150C lacks.

A shredder loud enough to interrupt a call doesn’t get used during work hours — and a shredder that doesn’t get used is a security hole with a power cord. The 79Ci is a SilentShred model, Fellowes’ quiet-operation engineering, which keeps it noticeably below the vacuum-cleaner range of typical consumer machines (70+ decibels under load) even while working through a stack. In a shared home office, that’s the difference between shredding between meetings and saving it all for after hours.

We score Noise from quiet-operation engineering claims cross-checked against owner-reported experience under load, rather than from a single decibel figure — manufacturers are inconsistent about publishing measured numbers, so we won’t present one we can’t stand behind. On that basis the 79Ci’s SilentShred design and generally favorable owner feedback place it at a solid 8.0, among the quieter machines in the lineup and a slight step below only the very quietest micro-cut Fellowes.

Bottom line on noise: SilentShred makes the 79Ci quiet enough to run during a workday without clearing the room — a solid 8.0.
