The Anker power core II 20000 mAh comes in two matte colors – black and a very cool looking white with four blue LED indicators. The matte finish ensures that the outer surface remains fingerprint free and looks subtly beautiful as well.

The power bank has a dual layer design. The inner metal shell provides protection and ruggedness while the outer polycarbonate layer ensures a smooth outer surface that does not scratch other items in your bag.

ANKER POWER VOLTAGE BOOST REVIEW

Anker claims that the voltage boost feature senses the resistance of the cable and increase current accordingly. However, this feature is important when you are charging your device using long cables as such cables have high resistance that wastes current and leads to slower charging eventually.

The reason why i always recommend users to use shorter and high quality cables, is as a result that they make your power bank charge last longer and charge your device faster, Anker power voltage Boost will take care of one of these issues by increasing current to charge your device faster.

INPUT & OUTPUT

Anker PowerCore II 20000 is one of the few portable chargers to feature two input ports. The high capacity power bank offers two micro USB input ports rated at 5V/2A each for recharging its batteries.

With supports for up to 4 Amperes input current, the Anker PowerCore II 20000 can fully charge in under 6 hours.

Dual input charge is a feature that is exclusive in power banks with more than 20,000 mAh capacity, but the PowerCore II 20000 is taking advantage of it. You can either use two individual chargers or a multi-port charger to charge-up the power bank.

Meanwhile, the Anker PowerCore II 20000 offers three USB output ports. Each of the ports can support up to 3 Amps. However, the total power output of the portable charger is capped at 6 Amps.

This means the ports can deliver the 3 Amperes maximum current only when one or two of the ports are in use. When all the three USB output ports of the power bank are in use, each one can deliver a still impressive 2 Amperes.

The power bank can charge your smartphone multiple times before requiring a recharge during the course of the day.
