How Long Should the KaiBot Battery Last?

How long should the battery on my KaiBot last?

How long KaiBots battery lasts depends on a couple of factors 

Screen-free mode :  This mode uses the least amount of battery and KaiBot will last the longest.
Apps - Bluetooth :  Once you pair KaiBot with any of the companion apps like Kainundrum, Market Math, Literacy Kitchen etc battery usage is significantly reduced.
Battery runtime

There are two versions of KaiBot 

How to tell the difference between version A & B is by looking at the battery capacity, printed on the battery (refer to  image below)

Version A - 500mAh                                                                    Version B- 300mAh 

KaiBot 500mAh and 300mAh batteries













Charge via USB cable
Charging via a mains powered adapter 5v 1.0A provides a reliable method to charge your KaiBots. 
  1. Use a Mains Power Adapter: 5v 1.0A or greater, refer to picture below.
  2. Micro USB or USB C: depending on your KaiBot version  
  3. Charge time: Charge for 1hr to get 80% charge

Charge via Charge Dock

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)

  • 3 docks → 5V, 2.0A (or higher)
  • 4 docks → 5V, 2.0A (or higher)

  • 5–6 docks → 5V, 3.0A (or higher)

Key Notes:

  • 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.


3 KaiBot Charging Docks requiring 1.5A
Charge via Charge Case (1-10 KaiBots)

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.

  • Warning
    Do not charge KaiBots with the case closed or zipped up, as this may cause overheating and is a fire hazard.

Notes
Avoid using low power USB ports for charging such as Laptop, PC and desktop USB ports as they may not provide enough current

Charging Tips


📘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.


📘Long term storage: Charge KaiBots for 30 minutes, before storing for several months, to keep the battery healthy.

📘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.
