If not, please contact our service support team:support@ocoopa.com.

A2: 118s: 2-3 hours charging can support 4-6 hours

        A8: 4-5 hours charging can support 8-12 hours

        H01: 7-8hours charging can support 8-15hours

        A9: 3-4 hours with PD charger charging can support 8-13hours

 

Q3: What is PD charger?

A3: It is a fast charging device. It provides higher output voltage up to 9V and current up to 2A for quick-charge-enabled hand warmers like H01PD, A9PD, or phone like iPhone XS. If you do not have a PD charger, you can have a try OCOOPA PD charger:

 

Q4: Why it shows 1 green light when charging?

A4: If it shows 1 green light, it is on fast charging mode. And it will shows 3 blue light after full charge.

 

Q5: It is too hot on level 1.

A5: We have upgraded the heat setting this year and enhanced the power as we received lots of feedback saying the hand warmer is not hot enough for outdoor sports. So it may be hot when we use it indoor or when it's cold, so we suggest to use it with the portable pouch when it's not cold yet. And we think you can still try it in the next few months when it's getting colder. If you are always not satisfied with the item, you can contact our support team for a refund or replacement.

 

Q6: Not charging after a long time no use.

A6:In your case, the battery is desactived after long time no use, so I suggest you to leave it charged for 10 hours and check the indicator lights.
Please contact our support team if it does not work properly after these steps. We'll resend or refund you.

 

Q7: My product cannot heat up continuously, the temperature varies between cold and warm.

A7 :Our hand warmer has a Temperature-Control& Variable Frequency function. When the hand warmer reaches 131°F, it will stop working. Then, when the temperature goes down to 118°F, it will start working again. Unstable heating of the product is usually caused by an extremely cold environment or using your icy hand to touch our product.

 

Q8: Never charges fully or cannot charge (only one LED bulb lighting up on the LED indicator).

A8: ① The model of the charger is not compatible with our hand warmer. (Samsung’s chargers often have this issue. If this is the case, please switch to any other charger with 1.5-2A input power.)

② Charging cable has loose contacts, please try to change the charging cable. If the problem still exists after the above operations, please contact us via our email:support@ocoopa,com

 

Q9: Battery life has shortened since first purchasing it.

A9: The following  incorrect uses will shorten the battery life and use time.

① Use the product before the battery is fully charged.

② Charging after fifirst receiving the hand warmer without advanced discharging. In order to protect the battery life, please charge the product to the full capacity when empty
