Petlibro vs PETKIT: for most households the PETLIBRO Granary 5L WiFi is the better buy, because it holds more food, runs on D-cell backup and carries a 24-month warranty. Pick the PETKIT Fresh Element Solo if you have a small counter, a single cat and want a 3L feeder with an app. Add a camera model only if you want to watch the bowl.
PETLIBRO Granary WiFi 5L
PETLIBRO lists 5L capacity, up to 10 meals a day, a desiccant bag with a sealing strip and USB or D-cell backup power. Its 24-month warranty beats the one-year default on many feeders. For the money it gives the most food per refill. The catch is footprint: it is the biggest unit in this guide, so measure your counter.
Check price on Amazon →You want one concrete thing: your pet fed on time when you are stuck at work, delayed on a flight or asleep. An automatic feeder does that, but a cheap one that jams or loses power is worse than a bowl. This is a researched comparison built from manufacturer pages and listings, not a field test. We computed the capacity math ourselves.
Our pick: PETLIBRO Granary 5L WiFi. It holds 5L, schedules up to 10 meals a day and has a 24-month warranty per PETLIBRO. Smaller space or single cat: PETKIT Fresh Element Solo, 3L and 1.33 kg of food. Want to see the bowl: the PETLIBRO Granary Camera. These feeders handle dry kibble only. Wet food, and anything you want to portion for a medical diet, needs a different plan.

Our picks, one by one
PETLIBRO Granary WiFi 5LOur Pick
PETLIBRO lists 5L capacity and up to 10 meals a day, with a built-in desiccant bag and sealing strip to keep kibble dry. Power is USB or DC 5V with three alkaline D batteries (not included) as backup per PETLIBRO's regional store. The AU store lists kibble sizes of 2 to 15 mm, and the warranty is 24 months. Because the hopper is larger, you refill less often, which means fewer chances to forget.
Check price on Amazon →PETLIBRO Granary Camera 5LBest With Camera
PETLIBRO's store lists a 1080P HD camera with infrared night vision, a 145 degree wide-angle lens, 5L capacity, 2.4 and 5GHz Wi-Fi and a 24-month warranty. It uses a DC 5V adapter with D-cell backup per the AU store. Because the camera shows the bowl, you see whether a cat finished the meal and whether kibble is jamming. It does not tell you why your pet is not eating. For that, call your vet.
Check price on Amazon →PETKIT Fresh Element SoloBest Compact
PETKIT lists the Solo (P570) at 3L, up to 1.33 kg of food, which it says is about 15 days for an adult cat. Retailers list up to 10 meals a day, 2.4GHz Wi-Fi plus Bluetooth, kibble under 12 mm, and a desiccant bag with a sealing strip. Power is USB plus an optional backup of five AAA alkaline batteries (not included). The app also controls portions. Freeze-dried food should stay under 20% of the portion, per listing.
Check price on Amazon →PETKIT YumShare Solo 2 (3L camera)Camera on a Small Feeder
PETKIT's YumShare line adds a camera to a 3L feeder. It is the compact camera option if the 5L Granary is too big. We list it because it is the closest PETKIT answer to the PETLIBRO camera model, but its specs are the least documented in this guide, so read the Amazon listing carefully and compare capacity and warranty with the Granary.
Check price on Amazon →The capacity table
PETKIT says its 3L hopper holds 1.33 kg of food, which gives a density of about 0.44 kg per liter. We applied that to 5L (about 2.2 kg). Real kibble varies in density, so treat this as an estimate. Daily amounts are examples only. Follow your food bag and your vet for your own pet.
| Hopper | Estimated food | Days at 60 g/day | Days at 90 g/day | Days at 250 g/day |
|---|---|---|---|---|
| PETKIT Solo 3L | 1.33 kg | 22 | 15 | 5 |
| PETLIBRO Granary 5L | about 2.2 kg | 37 | 25 | 9 |
Formula: days = hopper kg / daily grams x 1000. 5L estimate = 5 x (1.33 / 3).
You rarely need a full month of food in a hopper, and freshness drops the longer it sits. The point is the refill gap: a 5L hopper holds a medium dog's food for about a week to nine days, while the 3L one is a better match for a cat.
How we chose
We compared the PETLIBRO Granary line and the PETKIT Fresh Element Solo because both brands are sold on Amazon.com and both publish capacity, meal count and backup power. For each feeder we checked capacity, number of meals per day, how power outages are handled, kibble size limits, freshness features and warranty. We left out gravity feeders that cannot schedule, wet-food feeders and generic unbranded units. Prices are rounded. We did not find independent lab testing of jam rates for either brand, so we cannot rank them on reliability.
Set-up checklist before you trust it
- Use the right network. Join the feeder to your 2.4GHz Wi-Fi band. Both brands list 2.4GHz support, and listings disagree about 5GHz.
- Fill with your pet's own food. Different brands of kibble differ in size and shape. Check the diameter against the limit: under 12 mm for PETKIT, 2 to 15 mm on PETLIBRO's AU page.
- Insert the desiccant. Both models use a desiccant bag and sealing strip. Replace the bag on the maker's schedule so kibble stays dry and crunchy.
- Run a manual feed. Press the button and watch the portion drop. Weigh it on a kitchen scale once so you know what one portion really is.
- Load the backup batteries. Three D cells for PETLIBRO, five AAA for PETKIT. Pull the USB cable and confirm the feeder still dispenses.
- Set a schedule slightly off the hour. Pets learn the sound, and a feeder at 6:00 sharp can mean a 5:45 alarm from your cat.
- Give it a 48-hour home trial before you leave for a trip.
Camera feeders: what you gain and what to check
A camera adds one useful thing: you can see that the meal landed and that your pet ate it. PETLIBRO's camera feeder lists a 1080P camera, infrared night vision and a 145 degree lens. That is enough to see the bowl and the pet, not to read a label from across the room.
There are trade-offs. A camera is another device on your home network, so use a strong, unique Wi-Fi password and keep the app updated. Video may require a cloud plan after an included period; one US listing shows three months of storage, so read the terms before you count the camera as free. A camera also does not make a pet safe. It shows you a problem, and then you still need to act or call someone. If your pet stops eating, skips meals or looks unwell on screen, contact your vet. The feeder is not a health monitor.
Multi-pet homes: the part feeders do not solve
Neither feeder in this guide recognizes individual pets. If two cats share one bowl, the faster eater wins. Two options help. Feed in separate rooms with a closed door, or use two feeders on a schedule. PETKIT sells higher-end feeders with pet recognition, but they cost more and their specs differ by listing, so we do not recommend them without a clear model name and a read of the manual. If one of your pets is on a special diet, keep the automatic feeder for the other pet and hand-feed the special diet.
Mistakes that cause empty bowls
- Filling a hopper with treats, freeze-dried chunks or oily kibble. These jam the auger.
- Skipping the backup batteries because the router and the power both seem reliable. They are, until they are not.
- Assuming the app schedule is saved in the feeder. Check the manual for what happens if Wi-Fi drops.
- Leaving a full hopper for weeks. Food goes stale even with desiccant, so refill on a routine.
- Moving the feeder to a spot where the pet can tip it over. Put it on a flat, non-slip surface or against a wall.
Power, jams and the failure that matters
The real risk with any automatic feeder is silent failure: a power cut, a lost Wi-Fi connection or a kibble jam while you are away. Plan for all three.
- Power: Both brands run on USB power and take battery backup. PETLIBRO uses three D cells and PETKIT uses five AAA, neither included. Put in fresh batteries before every trip.
- Wi-Fi: Schedules are stored in the feeder in most apps, but check the manual. A feeder that depends on the cloud to dispense is a risk when your router fails.
- Jams: Use kibble in the stated range: under 12 mm for PETKIT, about 2 to 15 mm for PETLIBRO's AU listing. Odd shapes, treats and sticky kibble jam hoppers.
- Test run: Run the feeder for a full 48 hours with your own food while you are home.
Which one for which home
- Two cats or a medium dog: PETLIBRO 5L. Note that a feeder with one bowl does not stop a bossy pet from eating the other pet's meal.
- One cat, tiny counter: PETKIT Solo.
- Anxious feeder, you want proof: PETLIBRO Camera.
- Pet on a prescription or weight-management diet: ask your vet before automating portions.
Our verdict in three rules
- If you want the most food per refill, the longest warranty we found and D-cell backup, buy the PETLIBRO Granary 5L WiFi.
- If your counter is small and you feed one cat, buy the PETKIT Fresh Element Solo. Its 3L, 1.33 kg hopper holds roughly 15 days of food at 90 g a day, which is more than any trip you should leave a pet alone for.
- If you want to see feeding happen, add a camera, but treat the video as a convenience and plan for the cloud terms.
None of these replaces a person. Water, litter and a quick look at your pet matter more than the feeder. If you travel often, pair the feeder with a neighbor or sitter who checks in, and keep our other cluster guides on litter boxes and odor in mind if your pet stays home alone for days.
One last buying tip: check the model name on the Amazon page against the names above. Both brands sell near-identical titles in different capacities and with different cameras, so a quick match of the title avoids ordering the wrong variant.
Who should NOT buy an automatic feeder
Skip it if your pet eats wet or raw food only, if you need portions that match a vet-directed diet down to the gram, or if you are gone for more than a couple of days with no one to check in. A feeder cannot notice a pet that stops eating. Do not use it to replace a pet sitter on a long trip. If your pet bolts food, a slow-feed bowl and a smaller portion are safer than a feeder that dumps a meal at once. Ask your vet about any change in appetite.

Check price on Amazon →Frequently asked questions
Is PETLIBRO or PETKIT better?
For most homes PETLIBRO's Granary 5L is better because it holds more, uses D-cell backup and carries a 24-month warranty per PETLIBRO. PETKIT's Solo is the better fit for one cat and a small counter.
Do automatic feeders work during a power outage?
Both brands accept battery backup. PETLIBRO lists three D batteries and PETKIT lists five AAA, neither included. Install fresh batteries before a trip.
Can automatic feeders handle wet food?
No. The feeders here are for dry kibble. PETKIT also allows freeze-dried food under 20% of the portion, per its listing.
How many meals can an automatic feeder dispense a day?
PETLIBRO lists up to 10 meals a day on the Granary WiFi, and retailers list up to 10 for the PETKIT Solo. Some listings say 6, so check the exact model.
How long can you leave a pet with an automatic feeder?
A feeder only solves food. Water, litter and safety checks still need a person. Many owners limit unattended time to a couple of days; ask your vet what suits your pet.
