Meet Ultra, the purifier

that smiles back! 

Thanks for choosing the 

Steripen Ultra and 

congratulations on your 

purchase of the world’s most 

advanced portable 

UV water purifier!

Ultra is built to be simple, 

straightforward and safe. If 

after reading this guide you 

have any questions, please 

don’t hesitate to email us 

[email protected]. We love 

hearing from you! 

Thanks again and happy trails 

from your friends at Steripen!

P.S. Don’t forget to recycle the 

packaging!

If Ultra’s battery is charged, you are carefully following the 

operating instructions and Ultra still isn’t working, it might need 

professional repair work. Either bring Ultra to your local dealer or 

get in touch with us at 1-888-826-6234. Do not try to fix Ultra 

yourself. 

The water is safe to drink!

Ultra’s bulb has around 75% of 

its life left (approximately 6,000 

treatments) and its battery is 

roughly 75% full.

The treatment was successful 

but Ultra’s UV bulb is near the 

end of its life and has fewer 

than 100 treatments left.

Getting to know Ultra

Ultra’s Anatomy

It’s cold out and Ultra needs to warm 

up. A treatment will take a little extra 

time while the bulb reaches the right 

temperature. This feature adds a few 

seconds to ensure safe treatment.

Ultra didn’t have enough power in its 

battery to safely treat the water. 

Charge and try again.

Easy to Use 

Before using

Charge battery.

From a wall outlet or computer’s 

USB port.

Step 1 

Push button. 

1x      for 1 liter, 

2x      for 0.5 liter.

Step 2 

Place lamp in water. 

Submerge metal sensor pins.

Step 3 

Stir until you see the smile.

Dry bottle mouth before 

enjoying.

Ultra wasn’t in the water long enough 

to make it safe. Make sure the water 

sensors stay fully submerged 

throughout the whole treatment.

Ultra couldn’t treat the water because 

either the lamp is completely used up 

or it has been damaged.

Ultra’s USB-rechargeability offers a variety of recharging 

choices. Power up from an electrical outlet, a computer’s 

USB port or a portable solar panel. 

Ultra Charging Options 

From a solar charger 

(depends on charger)

Connect Ultra to a solar charger via the USB cord and 

position the solar charger so that it is 

directly 

exposed to 

the sun. Reposition the solar charger during the day for 

best performance. 

From a computer 

(3-5 hours)

Plug the USB end of the included cord into a computer’s 

USB port and connect Ultra via the micro USB end of the 

cord. Make sure that the computer is connected to a power 

source and doesn’t go to sleep during charging.

From an outlet 

(2-3 hours)

Attach the USB cord to a wall adapter’s USB port and plug 

both into a wall outlet. Plug the cord’s micro USB end into 

Ultra’s micro USB port and place it on a secure surface.
