This mobile phone charger is the same as using a 1 amp wall charger. How many hours it will take to charge your phone depends on both the capacity of your phone battery and the depletion of the charge. Example, if your battery requires 2000mamps and it is completely empty, it will take approximately 2 hours to charge your phone.

This Power Bank Charger is small and easy to carry.

The Power Bank 4000mah will charge all mobile phones using the the micro-USB connector or the Apple Lightning connector. It will not charge phones using the C connector.

One can also use it for 5V to power development boards.

  • Input voltage: 5V @ 1 amp.
  • Output voltage: 5V @ 1 amp.
  • Certifications: CE, RoHS & FCC.
  • Size: 104.5mm x 68.65mm x 9.7mm or 4.1" x 2.68" x 3.875".

    Yes!

    What does 4000mAhr mean?

    mAh means milliamp hours (1000 milliamps = 1 amp) 4000 mAh = 4 Amp hour. This means that it will discharge 1 amp for 4 hours. This is the measure of available current inside the Power Bank that can be delivered for one hour. For most mobile batteries the use lithium cobalt electrodes, this number should be multiplied by .8 or 80% because the phone will shut off and show empty when the battery voltage falls to 3.0 VDC. Therefore, the deliverable current is actually 2080 mamps. The shut down voltage of 3 VDC leaves a little charge in the battery for emergency mode a well as enough voltage so the charging circuit can read the battery.
