use of this product.

To use this product comfortably

● Hydrogen is not generated even though you turn on the power

switch.

Please charge if blue LED goes off before the specified time.

If hydrogen can’ t be generated even though blue LED is turned on, it might 

be due to low hardness water such as pure water (reverse osmosis water). 

Please change the water to tap water and confirm once again that hydrogen is 

generated.

● LED does not “turn on” or there is no “beep” sound even though

youturn on the power switch.

Just wait for 4 minutes after poring tap water or mineral water

available on the market!Hydrogen water can be generated even

while charging.

It might be out of battery. Please charge once again and turn on the power 

switch.

●It can’ t be charged (red LED does not turn on)

Please check that AC adapter is properly plugged into the outlet.

Please check that USB code is properly plugged into AC adapter and USB 

supported devices.

Please check that USB code is properly plugged into cable entry of the socket 

with correct direction.

The product can’ t be charged in case there is no electricity in the outlet or in 

case USB supported device is not turned on.

Voltage may get insufficient if you use other than the supplied AD adapter.

LED blinks in red or does not turn on if charging voltage is insufficient. In that 

case, please change the port to plug in.

●Water leaks

Please contact us or the shop where you purchased this product if

you still have the problem.

Please check if cap and socket are closed properly.

※Water may remain in the gap between body glass and socket. This is not water 

leakage so please wipe off properly.

Dissolved hydrogen decreases over the time.

Please use “10 second regeneration function” to retrieve dissolved hydrogen

if more than one hour passed since generation.

※Hydrogen concentration may be low when regenerating after a few hours.

4 minute generation by double pressing is recommended if more than 4 hours 

passed since generation.

Troubleshooting

How to assemble and use the product

Product Standards

10 second regenerating function

1

 Assemble body glass and socket properly 

and remove the outside lid.

Pour your desired amount of water (within 

450ml) and double press the switch button. 

Hydrogen water generation starts in 3 

seconds.

2

 There is a “beep” sound and LED blinks 

twice in blue before hydrogen (bubble) is 

generated from electrode plate.

3

 There is a “beep” sound 4 minutes after 

generation and it is completed if blue LED 

turns off. Please enjoy fresh hydrogen water.

1)1 Hydrogen generation starts in 3 

seconds after pressing the power 

switch once.

Please make sure to remove the 

outside rid when regenerating as well.
2)There is a “beep” sound and LED in 

the center of generator blinks in blue 

before hydrogen (bubble) is generated 

from electrode plate.

There is a “beep” sound in 10 seconds 

and it is completed if blue LED turns off.

Please charge the product before use.

Please wash the product once before use although cleaning 

and hydrogen generation test are conducted before shipment.

Mineral and the smell of chlorine may accumulate in a top lid 

depending on the type of water and the environment of tap 

water. If you mind the smell, you can pour water into a cup to 

enjoy the tasty hydrogen water.

The container is 100°C heat-resistant, but using hot water of 

over 50°C makes the body glass hot and may result in danger.

Concentration may vary depending on water quality. High 

hardness water can generate more concentrated hydrogen 

water.

Low hardness water like pure water (reverse osmosis water) 

may result in less concentrated hydrogen water.

Please wash the inside every day to ensure a hygienic use of 

the product.

Pouring more than 450ml water and generating with an outside 

lid closed may cause explosion by high pressure and result in 

danger. Please make sure to remove an outside lid when 

generating hydrogen water.

Press and hold the power 

switch for more than 3 

seconds. You hear a “beep” 

sound and the power will off.
