PETKIT Solo vs Dual-hopper 2: One Hopper or Two?

The short version

These two PETKIT feeders both drop dry food on a schedule into one stainless bowl. The split is the hopper, not the brand.

Fresh Element Solo (model P570, ASIN B0CFV4B369) is one 3-liter hopper and app scheduling. It joins 2.4 GHz Wi-Fi only. YumShare Dual-hopper 2 (model P592, ASIN B0GSZ98F69) is a 5-liter body split into a 2-liter hopper and a 3-liter hopper, with a portion setting for each hopper and 2.4 and 5 GHz Wi-Fi. PETKIT’s product description says the two hoppers can hold different compatible dry foods or dispense a selected mix. Both sides still empty into the same bowl. The feeder does not identify which cat eats.

Buy the Solo when one dry food and a schedule are the whole job. Buy the Dual-hopper 2 when you will actually fill both compartments for two foods or a mix. Skip both when the food is wet, or when one cat must be blocked from the bowl. A second hopper does not lock anything.

This page uses the Fresh Element Solo review and the YumShare Dual-hopper 2 review. We have not operated either feeder. Facts come from those product pages, PETKIT’s manuals, PETKIT’s October 2026 model comparison, and the two Amazon listings, which we checked on Oct 23, 2026.

Side by side

The two portion figures for the Solo do not match each other. The Amazon listing checked on Oct 21, 2026 describes about 1/10 cup. PETKIT’s product page says about 10 g, which it calls roughly 1/12 cup, and the manual says the real weight depends on the size and density of the food. Treat both as published settings, not as a weighed result. During the return window, weigh a few portions of the food you actually use.

The Dual-hopper 2 portion settings also disagree. PETKIT’s official product page lists 1–10 portions per hopper per meal. The Amazon listing states 1–5 portions, as of Oct 23, 2026. Follow the manual and the app for the feeder you have.

On freeze-dried pieces, the sources also disagree for the Solo. PETKIT’s current product page lists freeze-dried pieces up to 0.35 in (about 9 mm), next to a 0.47 in kibble limit. The P570 manual cited on the Solo review applies 12 mm to freeze-dried pieces as well. Use the manual that ships in the box, and measure the widest piece. The Dual-hopper 2 manual and product page agree with each other: kibble up to 12 mm, freeze-dried pieces up to 9 mm.

One hopper, two foods, or a mix

Start with what goes in the top, because that is the feature you cannot add later.

The Solo stores one dry food. If you rotate foods, you empty it first. There is no second compartment and no mix setting.

The Dual-hopper 2 stores two foods at once. The manual splits the 5 L unevenly: put the food you use more of in the 3 L side (hopper 02). The manual also says not to pull the partition out while food is still inside. PETKIT’s description says you can dispense from one side or release a selected mix. That mix lands in the same stainless bowl. The feeder does not identify which cat eats, and it does not keep a special food away from a cat that can reach the bowl.

A second hopper is worth having only when both compartments have a job you can name: two kibbles you already use, or kibble plus freeze-dried pieces that fit the size limit. If one side would stay empty, you are getting a larger body, not two foods.

Capacity is a refill question, not a second decision

Three liters versus five liters matters for how often you open the lid. It does not, by itself, mean you need two hoppers.

PETKIT’s Fresh Element Solo page estimates the 3 L hopper at about 1.33 kg (2.9 lb) and describes that as on the order of 15 days for one adult cat. That is a brand estimate. It changes with kibble density and with how much you actually serve. The Solo manual also says portions can shrink when the food level is low, and are most consistent when the hopper is full. Do not plan a trip around the full 15-day figure.

The Dual-hopper 2’s 5 L is 2 L plus 3 L, so the smaller side runs out first if both sides dispense every day. Refill each side on its own schedule. A larger total does not mean you can leave the feeder unchecked for longer. Our guide to choosing an automatic cat feeder shows how to turn a daily amount into portions with the Solo’s listing numbers. This page does not set a daily amount.

The Solo’s listed size, from the Amazon listing checked Oct 21, 2026, is 12.8 x 10.94 x 7.28 in. PETKIT lists the Dual-hopper 2 at 5.5 lb (2.5 kg). The dual-hopper body is the larger, heavier unit in this pair. If the feeding spot is a tight corner, measure it before you assume the 5 L model fits.

Wi-Fi, and where the camera question goes

The Solo has no camera. The Dual-hopper 2 includes one. Whether that camera is worth having is a different decision. See PETKIT camera vs no-camera feeders.

Wi-Fi still decides whether this pair can join the network you have:

• The Solo joins 2.4 GHz only. If the router offers a combined network or 5 GHz alone, sort that out before the return window closes.
• The Dual-hopper 2’s product page and manual list 2.4 GHz and 5 GHz.

If the internet drops, both are documented to keep following the schedule already saved on the feeder. The Solo manual adds that meals during an outage can log as “unknown”, only the last 10 records update after reconnect, and you cannot edit the plan while it is offline. The Dual-hopper 2 product page says the feeder still dispenses on the saved schedule without internet. You still cannot change that plan from the app until it reconnects.

Power and what the batteries actually cover

Neither feeder includes its backup batteries.

The Solo runs from a DC 5 V USB adapter. PETKIT’s product page says the adapter is not included and calls for 5 V 1 A output. Backup is five AAA alkaline batteries, also sold separately. The manual says to install them while the hopper is empty, and that with no batteries fitted a power cut stops the feeder until mains power returns. PETKIT’s October 2026 comparison lists backup of up to 7 days for this model. That is a brand figure. This site has not timed an outage.

The Dual-hopper 2’s specs list a DC 6 V adapter and four alkaline D batteries. The batteries are stated as not included. Confirm on the live listing whether the adapter is in the box for this ASIN; a PETKIT bundle page that pairs this feeder with a fountain lists an adapter, and that bundle is a different purchase. With the four D batteries installed, PETKIT’s product page says the feeder still follows the saved schedule during a power cut. The same October 2026 comparison lists backup of up to 60 days. Again, that is PETKIT’s figure, not a duration measured here. The P592 manual says the camera indicator is off in battery mode, and it does not say whether video still works on batteries.

A full hopper and fresh batteries are still not a substitute for a person checking in. Either feeder can jam, and neither one notices a bowl that has tipped. For a trip longer than a short weekend, arrange a visit. If a feeder you already own stops releasing food, the automatic cat feeder not dispensing food guide walks through PETKIT’s own checks, including the separate feed buttons on the Dual-hopper 2.

If you would rather have no adapter, no batteries, and no app, that is a gravity feeder, not either of these. The gravity feeder vs automatic cat feeder comparison sets the Gardner Pet gravity set against the Fresh Element Solo.

Cleaning: one food path or two

Both formats need a wash. The difference is how many parts you handle and what must stay dry.

On the Solo, the manual says the food container, silicone dispenser paddles, lid, and stainless bowl can be washed with a little soap, rinsed, and dried. The main unit, which holds the motor, must not get wet. A desiccant packet sits in the lid; the manual has you install it at setup and take the used packet out when you clean. There is no camera housing to work around.

On the Dual-hopper 2, PETKIT’s product page says the unit is detachable for cleaning and lists a 304 stainless bowl and a fresh-lock lid. The manual’s take-apart order, shared with the other camera model in PETKIT’s troubleshooting notes, is: unplug, remove the desiccant and the bowl, release the PUSH buttons, lift the hopper, pull the dispensing vanes, and open the impeller cover to clear wedged kibble. Let the parts dry fully before they go back. The main unit still must not get wet. The camera-model notes warn that hard tools can scratch the plastic and affect the sensor, so use a sponge or soft cloth inside the hopper. Do not pull the center partition while food is still in either side.

Two hoppers mean two food paths to inspect. One jammed or empty side can look like a dead feeder if you only press one button. More parts do not mean the Dual-hopper 2 stays cleaner. They mean the cleaning job is longer. This site has not timed either routine.

More than one cat

“Multi-cat” is four different jobs, and these two feeders cover only some of them.

• More storage. The 5 L body holds more than the 3 L body. That is refill frequency, not access control.
• Two foods. Only the Dual-hopper 2 stores two compatible dry foods at once. They still meet in one bowl.
• A log, not a lock. Meal records do not stop a second cat from eating, and they do not split the bowl into two dishes.
• A cat kept out of the bowl. Neither feeder documents a gate, a microchip door, or a collar lock.

If one cat must be kept away from the food, look at a selective-access bowl instead. The RFID cat feeder buying guide explains collar-tag and microchip lids, and the HEAPETS RFID feeder review covers one model built for that job. A timed PETKIT dispenser and a selective bowl solve different problems. Some homes use both.

The wider set of timed PETKIT feeders is on the automatic cat feeder shortlist.

Availability and what to add

Check each live listing for the current seller and stock before buying.

• Fresh Element Solo (B0CFV4B369): Add a 5 V 1 A USB adapter if you do not have a spare, plus five AAA batteries for backup.
• YumShare Dual-hopper 2 (B0GSZ98F69): Add four D batteries. Confirm whether a power adapter is in this ASIN’s box.

The Dual-hopper 2 adds a second compartment, more capacity, and dual-band Wi-Fi. The extra hardware makes sense only when you will use both hoppers. The Solo is not the right feeder if you need two foods, and the Dual-hopper 2 is not the right feeder if one hopper already covers the routine.

Which feeder fits

• Choose the Fresh Element Solo if you serve one compatible dry food, you want meals on a schedule, you can join 2.4 GHz Wi-Fi, and you will fit five AAA batteries.
• Choose the YumShare Dual-hopper 2 if you will keep two compatible dry foods (or a mix that fits the size limits) in the two hoppers, and you will fit four D batteries.
• Do not buy the dual-hopper body for a camera alone. If you already know you want video and only one food, that is the YumShare Solo, not either product in the table above.
• Choose a gravity feeder instead if the cat already does fine with food left out and you want no power and no app. See the gravity comparison.

When neither fits

Skip both of these feeders when:

• The routine depends on wet food, chilled portions, or pieces larger than the stated limit. Both manuals are for dry food.
• One cat must be physically kept out of another’s food. A second hopper does not do that.
• You cannot name a use for the second hopper. Buying the Dual-hopper 2 and then leaving one side empty gives you a Solo’s job in a bigger body.
• You will not install backup batteries, or the only network you can offer the Solo is 5 GHz.
• You plan to be away for days with nobody looking in. Neither machine replaces a visit.
