Ocoopa hand warmer Q&A

Q1:Is hand warmer having flashing red then blue lights when switched on?

A1: If blinks blue and red light,you have to recharge it asap.

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

 

Q2:How long do rechargeable hand warmer last?

A2: Due to different battery power.

5200mAh: 2-3 hours charging can support 4-6 hours.

7800mAh: 4-5 hours charging can support 8-12 hours.

10000mAh: 7-8hours charging can support 8-15hours.

  9000mAh: 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: Hand warmer 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: Hand warmer 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 send you a replacement or refund you order amount.

 

Q7: My hand warmer 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

 

Q10:Why does the third blue light keep flashing no matter how long hand warmer is charged?

 The third blue light will keep flashing, even when fully charged, and will not turn solid state,the blue light will automatically go off when fully charged.You can double click the button, the three blue lights on means the hand warmer is fully charged.

 

Q11: What is the function of the hand warmer three charging ports.

 The three interfaces are type C, USB A and micro, the USB A interface is used for output, it can charge your phone, the type C and micro interfaces  is used for input, it can charge the hand warmer.

 

Q12:  How can I tell the color of hand warmers without opening the box?

You can tell by the model number on the back of the box, like:OC-118-BK-DE, there will be color abbreviations on the model number, the BK is black, BU is blue, O is orange, P is pink.

 

Q13.Can I use the same plug I use to charge my cell phone?

It depends on the specifications of your cell phone charger. Generally speaking, the 5V 2A charger can charge all models of our hand warmers. If your hand warmer is a quick-charge version, like A9 ,H01PD, you can also charge your hand warmer with the 9V 2A charger, it will charge faster.

 

Q14.Is the voltage for a regular plug in the U.S. OK for charging? (seems the brochure references inconsistent info on this)

In the United States, the voltage of a normal plug can be charged. If your hand warmer cannot be charged, please contact us again or send an email to our official website. We will help you.

 

Q15.Why won’t the hand warmer work after I see the 3 dots from charging it? (They leave it plugged in trying to turn it on)

There may be two reasons for this, the wrong way of use or defective hand warmer. If you fully charged your hand warmer (double click the button to show three blue lights)and press the button for about five seconds, the hand warmer does not light a fixed red light and gets hot, then you should receive a defective unit, please contact our official website, we will replace it for you.
Q16:Hand warmer No Charger Cord?
