1.       How do I know which powerbank suits my device?
Depending on individual needs and requirements, there are several general criteria to consider when selecting a powerbank:
a) Capacity
For example if your phone battery is 1500mAh and is 0% now, a powerbank with 2200mAh can charge your phone 1 time.  If your phone battery is 3000mAh and is 0% now, a powerbank with 2200mAh will not be able to charge your phone to full because the phone battery capacity is higher than the powerbank.  If you require a powerbank that is able to charge your phone several times, you need a powerbank with higher capacity.
b) Number of output
1 output to charge 1 device, 2 outputs to charge 2 devices.
c) Output specification
1A-1.5A output is generally for smartphones, 1.5A-2.0A output is generally for tablets.

2.       How long do I need to charge the powerbank for the first time and subsequent time?/ How many times can a powerbank charge my phone?
a) Yoobao powerbank is already pre-charged and ready to use.
b) Re-charging time depends on the capacity of the powerbank, remaining power in the powerbank and the power supply.
   Example:
-Powerbank: 13000mAh (0% remaining)
-Power Supply/ Input: 1000mA plug
-Calculation: 13000mAh/ 800mA = minimum 16.25 hours
  (Why 800mA? An estimate of 20% power is consumed during the charging/ discharging process)

c) Similar formula applies to calculate number of times a powerbank can charge a phone.
   Example:
-Powerbank: 10000mAh (full at 90%)
-Phone Battery: 1500mAh
-Calculation: (10000mAh x 90% x 80%) / 1500mAh = up to 5 times
  (Why 90%? Assuming the power bank is well maintained in good working condition and can conserve up to 90% power)
(Why 80%? An estimate of 20% power is consumed during the charging/ discharging process)

* Note that the calculation is based on normal condition whereby the powerbank or device (phone/ tablet) is not in use during charging process. A running device generally consumes power therefore if your device is actively in use during the charging process, the charging performance may not meet the expectation.
* The above calculations are examples made simple for easy reference. Accuracy may vary.

3.       Powerbank unable to charge my tablet?
a) We recommend powerbank with 2A output to charge tablets.  While some tablets can accept lower input (1A or 1.5A), the charging is slower and sometimes can only be charged when the tablet is in sleep mode.
b) Some tablet’s cables might not be compatible with power bank due to different cable chipset design. For Samsung Galaxy Tab in particular, we recommend using the cable and connector meant for power bank (comes with some power banks, also available for separate purchase at MDC Gadget Store).

4.       Powerbank battery drained off very fast?
a) Generally, a well maintained powerbank can retain up to 80-90% of its original capacity.  Please check your device (phone/ tablet) original battery capacity and the powerbank capacity.  Please also see answer 1.a. above.
b) The number of times a powerbank can charge your device very much depends on the capacity of both the powerbank and the device.  Examples of calculation shown in answer 2 above.
c) Please do not attach cables to the powerbank when not in use.

5.       Unable to turn on my powerbank?
a) It is possible that your powerbank is fully drained.  Please charge your powerbank.  The indicator will start blinking when the powerbank receives sufficient power.
b) It is possible that your powerbank went into sleep mode.  The powerbank will automatically cut-off the power and go into sleep mode when it detects possibility of over-charge/ over-discharge/ short-circuit.  This is sometimes due to faulty cable issue.  Please activate the “sleeping” powerbank by charging it with its wall plug (3-pin plug) and use a good condition cable.

6.       What is the lifespan of the powerbank?
Generally, a properly maintained powerbank can retain up to 80-90% of its original capacity at 400-500 charge and discharge cycle (charge then discharge = 1 cycle, regardless of whether you charge/ discharge it partially or fully).  Until your power bank no longer holds sufficient charge to meet your needs, you may choose to purchase a new one.
