Power Source
Always use a mains power adapter for the fastest and most reliable charging.
Each dock requires at least 0.5A of current.
When chaining docks together, make sure your adapter can supply enough current for all of them.
Power Adapter Requirements
1 - 2 docks → 5V, 1.0A (or higher)
4 docks → 5V, 2.0A (or higher)
5–6 docks → 5V, 3.0A (or higher)
Docks can be nested (daisy-chained) together.
Charging is faster in the first hour (the battery fills quickly, then slows down for the top-up).
For best results, avoid under-powered adapters — low current can cause slower charging or inconsistent performance.
The KaiBot Charge Case can charge 1 to 10 KaiBots at the same time.
Inside the case, there are 2 USB-A cables—each one connects to a chain of 5 nested Charge Docks.
The case uses a mains-powered USB power supply with 2 USB-A outputs, each capable of delivering 2 amps.
This means that a chain of 5 docks (charging 5 KaiBots) will draw the full 2A output if all robots are completely flat.
Flexibility
You can replace the mains adapter with a power bank for portable charging.


📘If KaiBot is completely flat, switch it off, and refer to charging via USB cable section, leave on charge for around 2 hours to restore battery condition.
📘KaiBot can also be charged when switched off. Again, push KaiBot onto the dock, and he’ll switch on and start charging or use the included charging cable.
📘When KaiBot is full, he will move away from the dock and stop charging. If KaiBot is full, he will not automatically navigate to the charging dock when placed on the purple charge tile.
📘Nap time, If you don’t keep KaiBot entertained, he’ll start getting sleepy. After 10 minutes of inactivity, he’ll turn off the screen and go into a light sleep to conserve battery. To wake him up, just move him around on a coding card or tile. After 30 mins of inactivity, KaiBot goes into a deep sleep and can only be woken by switching it off and back on again. In the deep sleep mode, the battery from a full charge can last around 2 days.
📘KaiBot making funny noises, clicking and not switching on correctly? KaiBot’s battery is exhausted and needs a good 2-hour charge. Even if the battery says full, leave KaiBot on charge for a couple of hours when this happens.
📘Not charging. If the charging dock does not have power (green LED) then KaiBot will fail to dock and charge.
📘Not docking correctly: If the charging dock is not aligned correctly to the purple tile, then KaiBot might fail to dock correctly.
📘Note: Magnets located inside the dock, purple charge tile and Kai-Tiles should help align up, but you might have to correct it slightly for better docking.
