Q: Can I get a full charge to my phone?

A: The common power bank capacity is 2200 mAh, which is the standard 18650 3.7v Li-ion battery. The standard power output is approximately 1650 mAh because it uses battery to convert 3.7v to 5v to charge your device. If your cell phone battery is 2000 mAh, it will NOT give your cell phone a full charge. Here is a list of some phones battery capacity and charge assuming you are using iStick 2200 mAh battery. If your device has larger battery, a larger charger is required.

iPhone 5 - 1440 mAh, One full charge
iPhone 5s - 1570 mAh, One full charge
iPhone 6 - 1810 mAh, 91% charge
iPhone 6+ - 2915 mAh, 57% charge
Galaxy S3 - 2100 mAh, 76% charge
Galaxy S4 - 2600 mAh, 62% charge
Galaxy S5 - 2800 mAh, 59% charge
Galzxy Note II - 3100 mAh, 52% charge
HTC One - 2300 mAh, 70% charge
Sony Xperia Z1 - 3000 mAh, 55% charge

 
 

Q: Why can't I get a full charge when device is in use while charging?

A: When you are charging and using your device at the same time, the power goes to support your device first before charging your device. In other words, the battery charger becomes the power source of your device instead of using the internal battery.

 

Q: What do the LEDs on iStick mean?

A: Each LED indicates 25% battery capacity. When the battery capacity drops below 25%, only one LED stays on. For example, if iStick only has 2% power left, one LED will stays on; however, it won't be sufficient to charge your device. Some cell phones suce as iPhone 5S will receive error message or flashing screen. To resolve this problem simply recharge your iStick again until 4 LEDs are on.

1 LED = < 25%
2 LED = < 50%
3 LED = < 75%
4 LED = < 100%

 
 

Q: How long does the iStick retain power when not in use?

A: The typical Li-ion battery loses 5% charge every month. If you don't use the iStick for 6 month, it will likely lose 25% to 30% of its battery power.

 

 
 

Q: What's the life cycle of Li-ion battery?

A: Rechargeable batteries have a limited number of charge cycles. Standard Li-ion battery has 500 charge cycles before needs to be replaced or disposed of. If you depleted the battery completely on every use, it is considered as one charge cycle. To maximize the lifecycle of battery, make sure to keep minimum 50% of battery at all time.
