Quick answer: PETKIT identifies the US EverSweet Max 2 UVC as model P4116. It has a built-in rechargeable battery and uses a USB power cable; the wall adapter is not included. PETKIT’s US Max 2 UVC bundle identifies the matching filter format as Filter Unit RECT. Do not substitute Filter Unit 3.0 P4161: PETKIT lists P4161 for other fountains, not P4116. The Japan-market P4171 reference is regional evidence and does not establish a US standalone package code. (PETKIT Max 2 UVC, US bundle, P4161 page)
This guide focuses on the exact Max 2 UVC generation and the buying checks that follow from its cordless design. For a wider comparison, see our water fountains guide and filters and parts guide.

Confirm the model
The reviewed US product page identifies the fountain as P4116 and distinguishes EverSweet Max 2 UVC from Max 2 and Max. PETKIT’s manuals index also lists these as separate model names. Check the label and keep the full name, including “2” and “UVC,” when looking for a manual, replacement part or listing. A retailer’s shorthand such as “Max” may not preserve the generation or UVC suffix. (PETKIT product page, manual downloads)
The product page gives a 3 L / 101 oz capacity and dimensions of 10.43 × 6.73 × 7.51 inches. These are useful fit checks for a counter or floor location; they do not describe how often a particular household will refill the fountain.
Cordless use and power
PETKIT lists a built-in lithium battery and USB power cable, with the adapter not included. That gives you two different placement decisions: whether the location is convenient for charging, and whether you have the appropriate USB power source available. Do not assume a wall adapter comes in the box. (PETKIT product page)
PETKIT advertises three operating modes and up to 83 days of battery use. Treat that runtime as the manufacturer’s claim rather than a measured result for every setting or household. The same page describes Bluetooth app connection; Bluetooth should not be confused with Wi-Fi or remote internet access. If you need to check or change a setting, plan to use the supported connection range and app instructions for this exact fountain.
A practical setup check is to identify a stable, easy-to-clean location, confirm how you will recharge it, and keep the power cable away from chewing or splashing. The official page describes the unit as cordless-capable; it does not mean the fountain never needs charging.
The filter boundary
Filter naming is the easiest place to buy the wrong accessory. PETKIT’s P4161 page names Filter Unit 3.0 and lists EverSweet 3 Pro, EverSweet 3 Pro (UVC), EverSweet Solo 2 and EverSweet Solo SE. The list does not name Max 2 UVC or P4116. (PETKIT Filter Unit 3.0 page)
For Max 2 UVC, PETKIT’s US bundle identifies Filter Unit RECT as compatible with Max 2 Cordless/UVC. That confirms the format for the bundle’s Max 2 UVC pairing, but it does not prove that every standalone regional package, seller title or part number is identical. Match the exact model label and package description at checkout. (PETKIT US Max 2 UVC bundle)
PETKIT Japan lists P4171 with Max 2 in its regional catalog. That is helpful regional compatibility evidence, but it does not establish that P4171 is the US standalone SKU or that a US listing with that code is the right package. (PETKIT Japan P4171 listing)
The safe decision is therefore specific: do not buy P4161 for P4116 by model-family resemblance. Look for PETKIT’s US Filter Unit RECT description and verify the exact package against Max 2 UVC before ordering. The official page gives a four-week filter replacement interval; treat this as PETKIT’s recommendation, not a guarantee of a fixed lifespan. (PETKIT product page)
Care and advertised features
PETKIT describes a UVC feature and stainless-steel water-contact components on the product page. Those are product descriptions, not independent measurements of water quality or health outcomes. Follow the manual’s cleaning and part-replacement schedule, and do not treat UVC as a substitute for routine washing or fresh water.
The manufacturer advertises an up-to-four-week filter interval. Your purchase decision should center on whether the exact replacement format is available to you and whether you can follow the cleaning routine, rather than assuming a particular consumable cost or lifespan.
Who it may fit
This fountain may suit someone who wants the option to place a fountain away from a permanent outlet and is comfortable maintaining a rechargeable device. It may be a poor fit if you need a model with a confirmed US wall adapter in the box, Wi-Fi-based remote access, or a replacement filter code verified from a standalone US package before purchase.
Use the exact model number P4116 when comparing offers. Check the fountain dimensions, intended placement, recharge plan and replacement-filter description. For broader part selection, our filters and parts page explains why an exact model match matters.
