When you connect your portable charger to your device, press the power button, your portable charger’s LED lights will turn on, indicating the amount of charge left, and your device should show that it is charging. Please make sure the device is compatible with your power pack.

You can charge your product with the AC adapter.

Most Energizer_® Power Packs have a built-in charge indicator. To activate the charge indicator, press the power button on your power pack. This will cause the LED light power meter to illuminate corresponding to the charge remaining inside the power pack. When the Energizer_® Power Pack is still charging, this light will flash, and when the power pack is fully charged, all led lights should remain illuminated.

Typically it will take up three to four hours to fully charge an Energizer_® portable charger after its initial charge. Smaller portable chargers should take less time, and larger portable chargers or external batteries may take slightly longer. For models with USB or micro USB input port, the output current from USB wall charger or PC USB port will inference charging time too.

Energizer_® products are rechargeable up to 500 times. Afterwards, the Energizer_® unit will begin to lose its ability to hold a charge. Battery cells are consuming materials; there will be a decrease in the device’s total power capacity as time goes by or after certain times of usage.

Yes, all power packs with 5V (USB) input can be charged with a USB cigarette lighter. Unfortunately, we don’t recommend using a cigarette lighter to charge our larger power packs with 19V input power.

Yes, it is possible to use our Energizer_® Power Packs as an A/C adapter for your device.

Yes, for portable charge with USB or micro USB input port, you can recharge your portable charge with any USB wall charger between 0.5A and 2A without any impact to the battery life.

No. Lithium polymer battery technology is not susceptible to any memory issues like NICAD and NIMH.

If you don’t plan on using your power pack for more than 6 months, we recommend that you store the battery with a 75% charge and recharge the battery every 3 months. If you store a battery when it is fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity, meaning it will have a shorter life.

Charging time will depend on “current (ampere)”. If device original adapter output current is close to power pack output current, then the charging time should be close to the charging time the device original adapter takes. If power pack output current is smaller, charging time could be longer. If Power pack output current is larger, whether the charging time will be faster will depend on device power design. (There could be input current limitation. ie, device takes only certain input current.)

We recommend using the power pack once your laptop or netbook battery starts getting low. XP8000/A is recommended for netbook or ultrabook that needs less than 45WH input power and XP18000/A is recommended for laptop that needs less than 90WH input power.

You can tell compatibility from laptop original charger (power supply). There should be output spec shown on laptop charger, which indicate the input power your laptop needs. Basically, the polarity of the charger needs to be positive to center; its output voltage has to be equal to XP18000/A output voltage. (XP18000A may support 8.4V, 9.3V, 9.5V, 12V, 15V, 16V and 19V by using different convert cable.) Some laptops have tolerance for input voltage. The output current is suggested to be +/- 1.5A compare with the output current of XP18000/A. The watt hour (output voltage*output current) of the charger can Not be higher than 90WH.

The XP18000/A can support the MacBook® series of laptops but will require a PC06 + an Apple MagSafe Airline Adapter. For the MacBook Pro with retina display and the MacBook Air, both use an Apple MagSafe 2.

The XP18000/A (18,000mAh @3.7V) has slightly over twice the capacity of the XP8000/A (8,000 mAh@3.7V). The XP18000/A also provides a higher power output than the XP8000/A, making it better suited to charge larger devices such as laptops.

The XP8000A and XP18000A are the only power packs that can charge three devices at the same time. The USB output is designed for 5V USB devices, such as cell phones, MP3s, and Bluetooth devices. The 12V output is for portable DVDs, portable printers, and other 12V electronic devices. The 19V is designed for laptops (XP18000A) and netbooks (XP8000A, XP18000A).

The XP18000 provides 5V/1A (USB), 10.5V/2A and 19V/3.5A output power, and XP18000A provides 5V/2A, 12V/2A and 19V/3.5A power. XP18000A is recommended for support 5V tablet. XP18000 provides 10.5V output which can support some Japan brand devices. Both models may also support 5.6V, 8.4V, 9.3V, 9.5V, 15V and 16V by using different convert cables.

Using correct voltage ensures that your product will not be damaged. Tolerance is typically around +/- 0.6V, but it will depend on device.

Electro-Magnetic Interference is an electrical disturbance that affects an electrical circuit due to electromagnetic radiation emitted from an external source (such as when you hold a cell phone close to a radio and you hear static). The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the circuit. Energizer_® patented circuit board design and parts help minimize any EMI concerns.

Electro-Magnetic Compatibility is a term used when an electronic device limits the amount of electromagnetic radiation and allows other electrical equipment to operate without fear of interference. Energizer_® Power Packs are designed with this in mind to minimize EMI.

Please check the AC adapter for the electronic device being charged to find the output voltage and amperage. The output power on device’s original adapter is the input power device needs.
