Eilik In-depth Review｜Specifications, Price, Color, Battery, and Voice Functionality [Latest in 2025]

Introduction: What is Eilik?

Eilik is an “emotionally expressive” desktop companion robot developed by Energize Lab. Eilik has a small, palm-sized body with a display that reflects facial expressions and multiple sensors that detect touch and vibration.

The device is equipped with “convenient” functions such as reactions based on the way you touch its head, stomach, back, etc., dancing, mini-games, and a Pomodoro timer, adding a sense of comfort and playfulness to your desk work. Another feature is that when multiple units are placed together, they behave in a social manner, “seeming to talk” to each other with a certain motion and sound effects. It should be noted, however, that this is not a two-way voice conversation, but rather a pseudo-conversation based on the exchange of programmed gestures and sounds ( official website ).

Good Points｜Eilik’s Attractiveness (subheadings to get to the point)

Intuitive interaction that returns “emotion” when touched

Tapping on the head, tapping on the belly, stroking the back – the response changes depending on the part of the body touched and the strength of the touch. The various facial expressions and body language, such as joy, sulking, surprise, etc., create a “response” like a small living creature. The attraction is that it is possible to change the mood even in a short period of time.

Multiple units are fun in a “herd” behavior.

When Eiliks are placed side by side, they respond to each other in a “chatty” manner with predetermined motions and sound effects. For example, they can be programmed to laugh, poke fun at each other, or sometimes fight, creating a “conversational” atmosphere that can be enjoyed visually and audibly ( Energize Lab official ).

Mini-games & utilities for the desk are not sobering.

It has a full range of lightweight functions, such as dance/music, Pomodoro timer, alarm, and story mode, that can be enjoyed even when left on the desk. It is perfect for those times when you want to change your mood “just a little bit” between work or study.

It can be played for a long time with regular updates.

The design is such that firmware updates will increase the number of facial expressions, voices, games, and other content. The “repertoire of personalities” will increase little by little, which is a nice feature.

Compact, lightweight design for easy installation

The main unit weighs about 230 g. Its small size (108 x 105 x 133 mm) allows it to be placed next to a monitor or on a bookshelf as if it were “living” there. A single USB-C cable is used. It looks lovely and looks good as an interior decoration.

Points for Improvement｜A detailed explanation of the “real voices” from the many reviews.

Short battery life (approx. 1.5 hours)

Nominally, the device runs for up to 1.5 hours and recharges in about 1 hour (USB-C). The battery will run out quickly if the device is used continuously for long periods of time or if it is “on while booting. It is realistic to use the power supply frequently, or to use a stationary constant power supply (cable connection) ( Companion Robot review ).

Time-consuming during major updates

Farm updates that add content may take a long time to download and apply. Since you cannot play during the update, this can be a small stress for those who want to touch it quickly between tasks ( Companion Robot review ).

Response patterns can seem monotonous.

The “emotion engine” has a wide variety of expressions, but after prolonged use, the repetition of movements can become annoying. Some users said they “get tired of the patterns after a few days” ( Companion Robot review ).

Sound effects and motor noise are bothersome in a quiet environment

While the operation and sound effects are lovely, they can be a concern in a workspace where quietness is important, and Amazon reviewers have noted that the sound is surprisingly loud ( Amazon review ).

Important: “Conversation mode” of voice is not supported.

Eilik does not support two-way voice conversation. Eilik is not designed to understand and interact with the user’s speech, but rather to “emit voice (sound effects)” in response to touch and motion. Some users have been introduced to a function that allows them to “record and play back their voice as if they were talking,” but this is in the category of voice recording and playback, not conversational AI ( Eilik support page ).

Official application/flexibility of cooperation is modest

There is no expansion through smartphone apps or cloud integration via Wi-Fi; it is a simple design that charges and updates via USB-C and is based on stand-alone operation. Therefore, it does not require a Wi-Fi connection or a regular app, but it is not highly expandable for this purpose ( official store ).

Durability and individual variability of moving parts

As is the fate of the toy category, with its small size and many moving parts, there is no zero chance of individual variability or sagging during long-term operation. They are vulnerable to strong shocks, drops, dust, and liquids, and should be handled gently on a desktop ( Companion Robot Review ).

Variation in availability and price (e.g., limited colors)

Prices rise and fall depending on the time of year and sales channel, and limited edition colors and sets tend to sell out quickly. If there is a color you want, it is a good idea to check the stock at the official store or authorized retailers as soon as possible ( official store ).

Pre-purchase checklist

Continuous operation: 1.5 hours → Power supply operation is also in view.
Voice conversation is not possible → “touch and play” design.
Expand the range of play by operating multiple units and updating.

summary

Eilik is a small companion that adds a sense of “life” and playfulness to your workspace. It does not have “all-around capabilities” such as voice interaction or long-lasting operation, but its value is concentrated in the brief, momentary experience of touching it, looking at it, and dancing with it. This is recommended for those who seek a “casual, palm-sized healing experience” that is different from the conversational, cuddly, and highly autonomous pet robots ,such as aibo.
