Fellowes Powershred 79Ci
The Powershred 79Ci is a quick, quiet-for-its-class cross-cut shredder with genuinely useful safety and jam-prevention features, though buyers who need the highest privacy level should look at micro-cut models.
What we like
- +Very fast in independent testing
- +Jam Proof System measures paper thickness before shredding
- +SafeSense stops the blades when hands touch the opening
- +Runs up to 20 minutes before cooling down
- +Shreds staples, small paper clips, cards and CDs/DVDs
- +Pull-out bin with bin-full indicator and castors for moving
What could be better
- −Cross-cut P-4 security, not micro-cut
- −One lab could not reliably shred the full rated 16 sheets
- −Bin can fill quickly given the speed
- −Occasional jams on envelopes with plastic windows reported
- −Needs regular oiling like all cross-cut shredders
Best for: Small offices with one to three regular users
Visit Fellowes Brands →A good paper shredder is still essential for any office that handles contracts, payslips, bank statements or customer data. This Fellowes Powershred 79Ci review looks at one of the brand's best-known small-office cross-cut models, which Fellowes continues to sell in several regions.
We based this review on Fellowes' product pages and user manual, TechGearLab's lab testing and owner feedback. We cover security level, speed, noise, safety features and running it day to day, and point out where the 79Ci falls short.
Design and everyday use
The 79Ci is a floor-standing shredder of roughly 54 cm tall with a pull-out drawer bin, so you do not have to lift the cutting head to empty it. Castors make it easy to roll under a desk. The control panel has forward, reverse and on/off buttons plus indicator lights for overheating, bin open, bin full, paper removal and SafeSense.
A flap over the entry slot helps contain fragments when you feed cards or discs. TechGearLab rated it the easiest to use in its group, praising the bin-full light in particular because it prevents the confetti mess of an overstuffed bin.
Security level: what P-4 cross-cut means
The 79Ci cuts paper into particles of about 4 by 38 mm, which corresponds to security level P-4 under the DIN 66399 standard used in Germany and Europe. P-4 is widely recommended for sensitive personal and business documents. Fellowes says a single sheet becomes a few hundred pieces.
If you handle highly confidential data, a micro-cut shredder at P-5 or above produces much smaller particles. That was the main reason TechGearLab scored the 79Ci lower on shred quality than micro-cut rivals.
Speed, capacity and run time
Speed is the 79Ci's biggest strength. In TechGearLab's testing it shredded at a much higher rate than any other model in the group, making short work of large clear-outs. Fellowes rates the run time at up to 20 minutes, after which the machine needs about 30 minutes to cool down. That suits Fellowes' guidance of one to three users.
Fellowes rates the capacity at 16 sheets per pass of standard paper. TechGearLab could only feed 14 sheets reliably, so it is safer to feed slightly smaller stacks. Heavier paper and humidity reduce capacity further.
Jam Proof System and SafeSense
Before shredding, the 79Ci measures the thickness of what you feed it. A coloured indicator shows green when you can add more, yellow when the load is ideal and red when you have inserted too much. If a misfeed happens, the shredder pauses and corrects itself automatically. Fellowes calls this 100% jam proof when used according to the manual.
SafeSense technology stops the blades if a hand touches the paper entry, a helpful safeguard for homes and offices with children or pets. Owners generally report few jams, though TechGearLab saw occasional stoppages on envelopes containing plastic.
- Green: room for more sheets
- Yellow: optimal load
- Red: remove some sheets before continuing
Noise, energy use and maintenance
Fellowes markets SilentShred for shared spaces. TechGearLab found the noise the most consistent and easiest to tune out of the models it tested, though still noticeable. An energy-saving system includes standby and a sleep mode that switches the machine off after two minutes of inactivity.
Like all cross-cut shredders, the 79Ci needs oiling to keep its capacity and avoid noisy running. Fellowes recommends oiling each time you empty the bin. Its warranty terms differ by country, so check your local Fellowes site.
What the 79Ci should not shred, and placement tips
The manual is clear about limits. Do not feed adhesive labels, continuous form paper, transparencies, newspaper, cardboard, large paper clips, laminates, file folders, X-rays or plastics other than cards and discs. Greeting cards with sound chips or batteries are a fire risk and must never go in. Feed cards and discs one at a time, holding them by the edge, with the safety flap in position.
Fellowes designs the machine for rooms between roughly 10 and 26 degrees Celsius with moderate humidity, and it must plug straight into a grounded wall socket rather than an extension cord. Keep it in a spot where you can reach the rear power switch, and avoid placing it near heaters or water. A disconnect switch lets you stop it immediately in an emergency.
If the motor keeps running with no paper in the slot, paper dust may be covering the infrared sensors in the entry. The manual explains how to clean them.
- Shred: paper, staples, small clips, cards, CDs/DVDs
- Avoid: labels, laminates, cardboard, newspaper, large clips
- Never: cards with batteries or sound chips
Who is the Fellowes 79Ci for?
It is a strong fit for small offices, home businesses and teams that shred in batches and value speed and safety. People who want the finest particle size or who shred continuously for long periods should look at micro-cut or larger commercial models instead.

Frequently asked questions
How many sheets can the Fellowes 79Ci shred at once?
+
Fellowes rates it at up to 16 sheets of standard 75 g paper per pass. Independent testing found 14 sheets to be the reliable maximum, so feeding slightly smaller stacks avoids problems.
What security level is the Fellowes Powershred 79Ci?
+
It is a cross-cut shredder producing 4 x 38 mm particles, which is security level P-4. That is suitable for most sensitive personal and business documents.
How long can the Fellowes 79Ci run?
+
It can shred continuously for up to 20 minutes. After that it needs a cool-down period of about 30 minutes.
Can the Fellowes 79Ci shred credit cards and CDs?
+
Yes. It shreds credit cards and CDs/DVDs one at a time, as well as staples, small paper clips and junk mail. It should not be used for adhesive labels, laminates, cardboard or large clips.
How often should I oil the Fellowes 79Ci?
+
Fellowes recommends oiling it every time you empty the waste bin. Regular oiling keeps capacity up and noise down.
Is the Fellowes 79Ci really jam proof?
+
Its system measures paper thickness and reverses misfeeds automatically, and most owners report very few jams. Fellowes' claim applies when you follow the manual, and testers still saw occasional jams on some envelopes.
The Fellowes Powershred 79Ci remains one of the more capable small-office shredders. It is fast, hard to jam and safer than basic models, with sensible touches like a pull-out bin and a bin-full light. Its P-4 cross-cut particles are enough for most documents, but not for the highest security needs. If speed and convenience matter most, it is a dependable pick.
