PS71 and PS72 2Hour Power


1. What is 2 Hour Power?
2 Hour Power is a Rayovac portable power charger that runs on one lithium CR123A battery and you can use it to charge Apple 30-pin or Micro USB powered devices, namely mobile phones. Rayovac 2 Hour Power comes in two models: Apple 30-pin and Micro USB.
2. What does “2 Hour Power” mean?
2 hour power means that when using one new Lithium CR123A battery, the 2 Hour Power charger will charge your smart phone to a level which allows for 2 hours of extended talk time (based on iPhone 4S and Samsung Galaxy S II models). Results may vary by device.
3. Which devices will 2 Hour Power charge?
Rayovac 2 Hour Power comes in two models: Apple 30-pin and Micro USB. The Apple 30-pin version chargers iPhone 4S, 4, 3GS, 3G, and iPod. The Micro USB version charges Samsung, Blackberry, Nokia, LG, HTC, Motorola, and most other micro-USB powered phones.
4. Does 2 Hour Power charge tablets?
No. 2 Hour Power does not provide enough battery power to effectively charge tablets.
5. How long does it take 2 Hour Power to charge my device?
2 Hour Power will start charging your device as soon as it is plugged in. Most devices can be used while being charged. 2 Hour Power will continue to charge your devices until the lithium CR123A battery is depleted. The amount of charge provided to your device varies as well as the time it takes to charge your device. Most smart phones will receive 30% charge from one lithium CR123A battery. The time to charge varies by device. It takes about 30-40 minutes to charge a smart phone an extra 30% (based on iPhone 4S and Samsung Galaxy S II models). You can stop charging at any time to save remaining battery charge.
6. Why is my phone not turning on right away when plugged into the 2 Hour Power charger?
When your phone is completely dead (at 0% charge), it will take approximately four minutes for it to “wake up” and turn on. This is normal and happens when using other charging devices such as the wall charger that comes with most phones.
7. Why isn’t my phone charging when I plug the 2 Hour Power into my device?
The 2 Hour Power Micro USB model has an on/off switch. Move the switch to the “on” position to begin charging your phone. If your phone is still not charging, make sure the CR123A battery is not completely drained.
8. Why doesn’t the 2 Hour Power Apple 30 pin model have an on/off switch like the Micro USB model has?
There is no on/off switch needed for the Apple 30 pin model. The 2 Hour Power Apple 30 pin model will start charging once it is plugged into your device and it will stop charging once it is removed from your device.
9. Will 2 Hour Power give all my electronics the same amount of charge?
No, the amount of charge will vary by device. The 2 Hour Power will give most smart phones 30% charge from one lithium CR123A battery. 2 Hour Power will continue to charge your device until the lithium CR123A battery is depleted.
10. Is the lithium CR123A battery still draining in the 2 Hour Power when it is not plugged into my phone?
The Apple 30-pin 2 Hour Power model is turned on as soon as it is plugged into your device to charge and will begin to drain. When the Apple 30-pin 2 Hour Power model is not plugged into a device to charge, the lithium battery will not drain. The Micro USB 2 Hour Power model has an on/off switch. When the switch is in the on position, the lithium CR123A battery will begin to drain. When the switch is in the off position, the lithium battery will not drain. 
11. Can I use part of the 2 Hour Power charge at one time and save the rest for later or for a different device?
Yes. You can stop charging your device at any time and continue to use the 2 Hour Power later or with a different device. Simply disconnect the 2 Hour Power tip from your device to stop charging. Make sure to move the on/off switch on the Micro USB version to the off position so the lithium CR123A battery does not continue to drain.
12. How do I know how much power is left in the 2 Hour Power charger?
There are no battery charge indicators on the 2 Hour Power. The charger takes about 30-40 minutes to charge a smart phone approximately 30% and then the battery will be depleted and needs to be replaced. You can remove the charger from your device at any time to save remaining battery charge.
13. What type of battery does the 2 Hour Power use?
2 Hour Power runs on one lithium CR123A battery. 2 Hour Power will continue to charge your devices until the one lithium CR123A battery is depleted. Rayovac lithium CR123A batteries have a 10 year shelf life.
14. Can I use rechargeable CR123A batteries in the 2 Hour Power?
Rechargeable batteries do not provide a high enough voltage for the 2 Hour Power to work.
