- Method: picks chosen from Amazon listings and brand specs; not hands-on tested; current Amazon prices are on the page; content checked 2026-09-28.
- Quick answer: Buy PETLIBRO if you feed larger kibble or want the biggest hopper: its Granary feeders hold 5 L and take kibble from 2 to 15 mm, and its camera feeder records to a microSD card without a plan. Buy PETKIT if you want a smaller 3 L feeder, face recognition for up to 15 pets on the camera model, or the longest cordless fountain run (up to 83 days per charge on the Eversweet Max 2, per PETKIT). Both brands sell their feeders' desiccant packs and their fountain filters on Amazon, and both put some camera features behind a paid plan.

## Key takeaways

- Hoppers: PETLIBRO Granary feeders hold 5 L; the PETKIT feeders here hold 3 L (12 cups), per each listing.
- Kibble: PETLIBRO says 2 to 15 mm; PETKIT says dry kibble up to 12 mm and freeze-dried up to 9 mm.
- Backup power: both run meals on batteries in an outage; PETLIBRO's camera feeder turns off Wi-Fi and the camera on batteries, and PETKIT says its camera is disabled in battery mode.
- Refills: PETLIBRO says change the feeder desiccant every two weeks and fountain filters every two weeks; PETKIT says its Filter Unit 3.0 lasts 30 days in normal mode, 60 in smart mode.
- Cordless fountains: PETKIT's Eversweet Max 2 runs up to 83 days per charge; PETLIBRO's Dockstream 2 cordless up to 30 days, each maker says, under the maker's own usage assumptions.

PETKIT and PETLIBRO make the same kinds of things, timed feeders, camera feeders and filtered fountains, and both sell them on Amazon through Amazon.com or their own stores. Buy PETLIBRO if you want a bigger 5 L hopper, larger kibble or a camera feeder that records to a memory card; buy PETKIT if you want a compact 3 L feeder, face recognition for several pets or the longest-running cordless fountain. This page compares both on the makers' own specs, then lists the refills each one runs on: desiccant packs for the feeders and filters for the fountains.

**How we chose:** we did not test these devices; specs come from each listing and each maker's product pages, and every pick was sold by Amazon.com or the brand's store and in stock on September 28, 2026.

## Feeders side by side

| Feeder | Hopper | Portions (per listing) | Kibble size (per maker) | Backup power (per maker) | Camera | Sold by | Amazon price |
|---|---|---|---|---|---|---|---|
| [PETKIT 3L Wi-Fi](https://petprooflab.com/food-feeding/petkit-vs-petlibro#product-B0CFV52Z1N) | 3 L (12 cups) | Up to 10 meals, 1–5 × 1/10 cup | Dry under 12 mm; freeze-dried to 9 mm | Batteries (not included) | No | PETKIT-US | see the current Amazon price on the page |
| [PETKIT 3L with Camera](https://petprooflab.com/food-feeding/petkit-vs-petlibro#product-B0GSYQ95J1) | 3 L | 1–5 portions per meal | Up to 12 mm (PETKIT page) | Battery backup; camera off | 1080p, 140° | PETKIT-US | see the current Amazon price on the page |
| [PETLIBRO Granary 5L Wi-Fi](https://petprooflab.com/food-feeding/petkit-vs-petlibro#product-B09S8WMJY9) | 5 L | Up to 10 meals, 1–48 × 1/12 cup | 2–15 mm | 3 D batteries (not included) | No | Amazon.com | see the current Amazon price on the page |
| [PETLIBRO Granary 5L Camera](https://petprooflab.com/food-feeding/petkit-vs-petlibro#product-B0B5ZGGWBQ) | 5 L | Up to 10 meals, 1–50 portions | 2–15 mm | D batteries; camera and Wi-Fi off | 1080p, 145° | Amazon.com | see the current Amazon price on the page |

Kibble limits and backup details come from PETLIBRO's pages for the [Granary Wi-Fi feeder](https://petlibro.com/products/petlibro-5g-wifi-automatic-pet-feeder) and [Granary camera feeder](https://petlibro.com/products/granary-smart-camera-feeder-for-pet), and PETKIT's pages for the [Fresh Element Solo](https://www.petkit.com/products/fresh-element-solo) and [YumShare Solo 2](https://www.petkit.com/products/yumshare-solo-2-automatic-feeder-with-camera), its 3 L non-camera and camera feeders.

## Hopper size and kibble limits

**PETLIBRO's Granary** feeders hold 5 L. PETLIBRO lists the Granary Wi-Fi as model PLAF103 with "Allowed Kibble Sized: 2-15mm," and gives the same 2 to 15 mm range for the camera model. Each portion is "about 20ml/10g ≈ 1/12 cup," it says, and the feeders are for dry food only: asked whether the Granary works with wet food, PETLIBRO answers "No."

**PETKIT's** 3 L feeders are smaller. PETKIT says its 3 L hopper stores "about 1.33kg (2.9lbs) of food, which is enough to feed an adult cat for 15 days," and asks you to "avoid dry kibble with a diameter over 12mm (0.47in) or freeze-dried kibble with a diameter over 9mm." Portions are 1/10 cup on the non-camera listing, and PETKIT's comparison chart gives 1 to 5 portions of 10 to 50 g per meal on its single-hopper feeders.

In practice: a cat on small kibble is fine with either. A large-breed dog kibble near 15 mm points to PETLIBRO, and so does a meal that needs more than five portions. Whichever you buy, weigh one portion of your own food, because a portion is a volume and kibbles differ. Our [automatic pet feeder guide](https://petprooflab.com/food-feeding/automatic-pet-feeders) explains how to check a feeder's portions against the amount your vet gives you, and how much to feed is a question for your vet, not the feeder ([why we say that](https://petprooflab.com/about#veterinary)).


## Power cuts, Wi-Fi and the camera

Both brands keep meals coming on batteries, but not everything else.

- **PETLIBRO Granary Wi-Fi:** "The USB adapter and battery backup ensure that even if there is a power outage, the feeder will continue to feed your pet," per PETLIBRO, using three alkaline D batteries you buy separately.
- **PETLIBRO Granary camera:** PETLIBRO says to use batteries only in emergencies, and that on batteries "the WiFi function, camera function, record button and reset button, are all disabled to extend battery life, while meal schedules will be carried out normally." It also says not to use rechargeable batteries.
- **PETKIT Fresh Element Solo:** "After installing five AAA batteries, the feeder will still dispense food according to the feeding schedule," per PETKIT, with the batteries sold separately.
- **PETKIT YumShare Solo 2:** PETKIT's page promises "14-Day Power Backup" and notes "Camera disabled in battery mode." The same page lists five AAA batteries in its specs and four D batteries in its FAQ, so check the manual in the box before you buy batteries.

So in an outage, neither camera feeder keeps streaming. Plan on a person checking in if you will be away overnight.


## Cameras and what needs a subscription

**PETLIBRO's Granary camera feeder** has a 1080p camera with a 145° lens and infrared night vision, and it "supports up to 256GB micro SD card (package not included) or Video Cloud (paid subscription)," per the listing. PETLIBRO adds that Video Cloud works with that feeder only and that each feeder needs its own subscription. Its newer Granary 2 Vision goes further on AI: PETLIBRO's page says a Petlibro Care subscription is required for alerts about changes in eating habits, and a Video Cloud AI subscription for recording and playback.

**PETKIT's camera feeder** has a 1080p camera with a 140° view, infrared night vision and face recognition for "up to 15 pets," per the listing. Its listing says "videos can be saved on secure cloud storage for easy viewing anytime (Certain services need to be purchased in the app)," and PETKIT's listing for its dual-hopper camera feeder advertises "free live streaming." The 3 L listing does not mention a memory card slot.

Both let you cut the camera: PETKIT's listing says you can set the camera's operating time and disable voice recording in the app. If a camera feeder is really about watching the room, compare it with a standalone camera in our [pet camera guide](https://petprooflab.com/home-beds/pet-cameras).

## Fountains side by side

| Fountain | Capacity | Power | Pump | Filter and interval (per maker) | Sold by | Amazon price |
|---|---|---|---|---|---|---|
| [PETKIT Eversweet Solo 2](https://petprooflab.com/food-feeding/petkit-vs-petlibro#product-B0B3RWF653) | 2 L | USB, always plugged in | Wireless pump | Filter Unit 3.0; every 4 weeks (Solo 2 FAQ) | PETKIT-US | see the current Amazon price on the page |
| [PETKIT Eversweet Max 2 Cordless](https://petprooflab.com/food-feeding/petkit-vs-petlibro#product-B0FHQC19RV) | 3 L | 5,000 mAh battery or USB | Wireless pump | Filter Unit RECT; every 2–4 weeks | PETKIT-US | see the current Amazon price on the page |
| [PETLIBRO Dockstream 2 Plug-In](https://petprooflab.com/food-feeding/petkit-vs-petlibro#product-B0FDKQGRCK) | 3 L | Adapter | Pump-free rotor | Dockstream filter; every 2 weeks | Amazon.com | see the current Amazon price on the page |
| [PETLIBRO Dockstream 2 Cordless](https://petprooflab.com/food-feeding/petkit-vs-petlibro#product-B0FDKVJNXB) | 3 L | 5,200 mAh battery | Pump-free rotor | Dockstream filter; every 2 weeks | Amazon.com | see the current Amazon price on the page |

The fountain details come from PETKIT's [Eversweet Solo 2](https://www.petkit.com/products/eversweet-solo-2) and [Eversweet Max 2](https://www.petkit.com/products/eversweet-max-2-uvc-pet-water-fountain) pages and PETLIBRO's [Dockstream 2 page](https://petlibro.com/products/dockstream-2-smart-fountain).

## Wireless pumps and cordless fountains

The two brands keep electricity out of the water in different ways.

**PETKIT** uses what it calls a wireless pump: on the Solo 2, "there are no wires inside the water pump fountain body, only one USB power cable on the base," and the body lifts off the powered base for filling. The Solo 2 must stay plugged in to run. The **Eversweet Max 2** adds a battery: "5000mAh high-capacity battery, service life up to 83 days," and PETKIT says "except for the battery pack, all other parts are dishwasher safe." In sensor mode, water runs for one minute when a pet comes within 3.94 inches.

**PETLIBRO's Dockstream 2** has no pump in the tank at all. PETLIBRO says a small magnetic rotor sits in the bottom of the tank and a magnetic driver in the base spins it, so "no wires are submerged in water." The cordless version gives "up to 30 days of battery life on a single charge," and PETLIBRO's footnote says that figure is "based on usage by a single pet in sensor-activated flow mode." Both Dockstream 2 versions weigh the water to track how much your pet drinks.

Treat both battery figures as each maker's best case: more pets, or continuous flow, will run a battery down sooner.


## The refills each brand runs on

This is the part you keep buying after the device itself.

| Refill | PETKIT | PETLIBRO |
|---|---|---|
| Feeder desiccant | Silica gel packs, 5 per pack ([Amazon](https://petprooflab.com/food-feeding/petkit-vs-petlibro), sold by PETKIT-US); the app sends a replacement reminder | Desiccant bags ([Amazon](https://petprooflab.com/food-feeding/petkit-vs-petlibro), sold by Amazon.com); change every 2 weeks, per PETLIBRO |
| Fountain filter | Filter Unit 3.0 (Solo, Solo 2, Solo SE, 3 Pro): 30 days normal mode, 60 days smart mode. Filter Unit RECT (Max): every 2–4 weeks | Dockstream filters: every 2 weeks for one pet, more often for several |
| Before fitting a filter | Soak at least 10 minutes, then reset the fountain | Soak 5 minutes, rinse 30 seconds |
| Fountain cleaning | Weekly in summer, every 2 to 3 weeks otherwise | Quick wipe weekly, full wash with dish soap |

PETLIBRO answers the desiccant question directly: "It is recommended to change the desiccant bag every 2 weeks to prevent mold growth," on its Granary pages; its desiccant listing on Amazon says "once every half month." PETKIT describes its desiccant as premium silica gel that "absorbs moisture to protect every kibble" and lists desiccant replacement among the feeder's app notifications, but its desiccant page gives no interval.

On filters, PETLIBRO's [filter guidance](https://petlibro.com/pages/how-often-should-i-change-the-filters) says "every two weeks" for one pet. PETKIT's [Filter Unit 3.0 page](https://www.petkit.com/products/filter) says "Replace every 60 days in smart mode and 30 days in normal mode," while its Eversweet Solo 2 FAQ says every four weeks, so four weeks is the safe reading. Our [fountain filter guide](https://petprooflab.com/food-feeding/fountain-filters-and-replacement-parts) lists which filter fits which fountain for both brands and three others.


## Who each brand suits

- **Buy PETLIBRO** for a large hopper, kibble up to 15 mm, a camera feeder that records to a memory card, or a fountain that measures intake by weight. Expect to change feeder desiccant and fountain filters every two weeks.
- **Buy PETKIT** for a compact feeder, face recognition across up to 15 pets, or a cordless fountain that PETKIT rates for up to 83 days per charge. Its filters last longer between changes, per PETKIT, but its feeders take smaller kibble.
- **Either** if you have one cat on ordinary kibble; then pick on the app you prefer and whether you want a camera at all.

For more fountains, see our [cat water fountain guide](https://petprooflab.com/food-feeding/cat-water-fountains) and our [Catit Flower vs PETLIBRO fountain comparison](https://petprooflab.com/food-feeding/catit-flower-vs-petlibro-fountain).

**Recalls:** we found no FDA or CPSC recall of either brand on our [pet recall page](https://petprooflab.com/recalls) or in the [CPSC recall database](https://www.cpsc.gov/Recalls) on September 29, 2026.

## Frequently Asked Questions

### Is PETKIT or PETLIBRO better for large kibble?

PETLIBRO. It lists kibble from 2 to 15 mm for its Granary feeders; PETKIT asks you to avoid dry kibble over 12 mm and freeze-dried pieces over 9 mm.

### Do PETKIT and PETLIBRO camera feeders need a subscription?

Not for live video. PETLIBRO's Granary camera feeder records to a microSD card or to its paid Video Cloud; PETKIT's listing says cloud storage and certain other services are paid in its app.

### Do the feeders work in a power outage?

Yes, on batteries you buy separately, but only the feeding schedule keeps running. PETLIBRO says its camera and Wi-Fi switch off on batteries, and PETKIT says its camera is disabled in battery mode.

### How often do I replace the desiccant in a PETLIBRO feeder?

Every two weeks, per PETLIBRO, "to prevent mold growth." PETKIT's feeders remind you in the app but its desiccant page gives no interval.

### Which cordless fountain lasts longer on a charge?

PETKIT rates the Eversweet Max 2 for up to 83 days; PETLIBRO rates the Dockstream 2 cordless for up to 30 days with one pet in sensor mode. Neither figure is ours.
