I've been using these for about 2 weeks now so I wanted to share my experience.
They both arrived in nice minimal packaging. Cardboard boxes. The battery bank contained the powerbank, a nice thick USB micro cable and a USB a to USB type c cable. Both are thick and should last a long time. The powerbank is a nice metal black one, with chamfered edges.
The wall adapter comes solo as the wall adapter itself. I received the black one made of plastic.
Ports- the battery has both 2 charging ports, 1 the qc 3 port and 1 regular 1amp port. Then there's 2 recharging ports, 1 microusb and 1 lightning port. I've got an iPad so if you have a lightning cable it'll actually take both the Lightning port and the qc micro USB port to recharge, speeding up the recharging process.
The wall adapter has a single USB A port, which is actually reversible so it'll take the USB end both ways. A nice touch.
Ok testing this I used both a G5 and I used the wall adapter to recharge the battery, since the battery is qc compatible for charging and recharging. The wall adapter is just as good as the oem wall adapter in charging the G5. Both chargers took about an hour to charge from a dead phone. Impressed.
Then I used the powerbank to charge the G5 using the qc3 port and included type c cable. Again it was charging the same rate, finishing at about an hour. Compared to a qc2 charger I'd say there's about a 10-15% difference due to the faster charging up to about 60-70% before trickle charging.
So for the powerbank recharging it with a normal non-qc took around 6-6.5 hours. So using the qc wall adapter it charged noticeably faster, at just over 4 hours. Then on top of that if you use both the qc charger plus a lightning cable it cuts about an hour off that. Very good results for a 10400 capacity. Was able to get over 3 charges on the G5 with room to spare. The battery has 4 lights that are blue, with the first one turning green when utilizing qc for both charging and recharging.
It's a great combo. I used the bank to charge the G5 and the extra port to charge Bluetooth headphones when needed. I like both products. Any questions let me know. Thanks!
