This Anker charger excels in build quality and is easily one of the best compact portable chargers available for both iPhones and Samsung and other Android phones.

Anker PowerCore II 6700 Charging
Anker PowerCore II 6700 supports a maximum charging output current of 2.4 amps. This enables it to charge both Android smartphones and iPhones at very good charging speeds. PowerCore II 6700 will charge all iPhones including the latest XS, XR, X, 8, 8 Plus etc. at speeds of zero to 50% in 40-55 minutes or at more than twice the speed of Apple stock iPhone charger (which charges at 1 amp).
The power bank will charge most Samsung and other Android phones at 2+ amp charging speeds, allowing it to charge most Android phones from zero to 50% in 50-60 minutes.
The PowerCore II 6700 has a true 6700 mAh battery capacity. This is adequate to fully charge all small-screen iPhones (8, 7, 6S, 6, 5S, SE) more than two times, and charge all the large-screen iPhones (including iPhone XS, XS Max, XR, X, 8 Plus, 7 Plus, 6s Plus) from 20% to 100% about two times. PowerCore II 6700 will charge most Samsung and other Android phones including the new Samsung Galaxy S10, S9 Plus, S9, S8 etc. from 25% to 100% about two times.
The portable charger is charged via a maximum of 2 amp input current over the micro-USB port and takes about 4 hours to get full-charged from empty.
Anker PowerCore II 6700 Design and Features
The narrow rectangular design of PowerCore II 6700 looks good and allows it to fit in easily in pockets as well as handbags. This portable charger has dimensions of 3.78 x 1.69 x 0.91 inches, which make it even smaller and lighter than Anker’s old PowerCore 5000 portable charger. PowerCore II 6700 is also smaller, lighter and faster charging than Anker’s older Astro E1 6700 portable charger.
The powerbank gets charged via a micro-USB port and has one regular USB port featuring Anker’s PowerIQ (smart device required input charging current detection and 2.4 amp maximum output) charging tech.
PowerCore II 6700 comes with 6 power LED indicators on the round power button. The outer surface of the power bank is textured and feels soft, leading to a firm grip. The feel and build quality of the powerbank is stellar though we would have preferred a slimmer design and a USB-C input port (like in the Anker Powercore Lite 10000) for charging the portable charger directly with the USB-C chargers of most samsung/LG/Android phones.
The power bank package includes a free micro-USB cable and a decent quality travel pouch.
Anker PowerCore II 6700 vs Jackery 6000 Bar / Bolt
Jackery 6000 Bolt and 6000 Bar are close competitors of PowerCore II 6700.
Anker PowerCore II 6700 has a higher output current of 2.4 amp when compared to the output current of Jackery 6000 Bolt/Bar power banks (2.1 amp). This leads to PowerCore II 6700 delivering slightly faster charging speeds for both iPhones and Android phones.
The battery capacity of the Jackery power bank is 6000 mAh and is lower than PowerCore 6700’s of 6700 mAh.
Considering all this, we can safely say that PowerCore II 6700 is a much better portable charger overall when compared to either the Jackery 6000 Bar or the Jackery 6000 Bolt, especially as all these chargers are available at comparable prices.
