The Anker PowerCore Speed 20000 power bank boasts both a Qualcomm Quick Charge 3.0 output for up to 24W power as well as a PowerIQ output for a simultaneous 10W charging on a second device. This gives you the flexibility to get multiple devices up and running again in the least amount of time possible.
While the functional design of the PowerCore range won't win any awards for style, the internals are not to be dismissed. The cutting-edge charging and safety technology inside gives you the peace of mind to take your PowerCore with you wherever you may go so that you're never without emergency power.
This package includes a travel pouch and 60cm Micro USB cable suitable for both charging the PowerCore as well as your own devices. And of course it's compatible with iPhone and iPad using your own Lightning cables! This is one beefy battery in a very handy form factor - no matter where you go it'll fit right in!
How much mAh charge is enough?
To get a rough idea of how may times your device can be charged by a given power bank, you first need to know the battery capacity of your gadget. For example, an iPhone X has a 2716mAh battery. Double that number (5400) and divide the powerbank capacity by this amount. This gives you a very rough idea of how many full charges you could get. You can inflate this number by working in the highest efficiency zone, recharging your device from no less than 20% to no more than 80% - this will give you the most charge duration overall!
Note: The PowerCore devices should be charged from a wall charger with 2A or greater output. Charging from computers, laptops or wall chargers with 1A or less will take longer and be less efficient.
