Couple of weeks ago I bought my first mobile battery charger – the Jackery Zen – and I'm thinking about returning it. This is because it doesn't work as intended for me. There are few issues and one of them is a deal breaker.
I bought the charger to charge, not only my Nexus 5 phone, but also my Plantronics BackBeat Go 2 Bluetooth headset. This charger is incapable of "normally" charging the headset. When the headset is plugged in, it would start charging, but it would stop charging momentarily. This is probably because the current draw is too low for the charger to detect that there is a device plugged into one of its ports. It works with neither of the two ports. Why I said that it cannot "normally" charge is because there is a way you can get it to work and that is by charging it together with the phone. Then it would not shut-off because the phone is draining the battery faster. I'm not sure if this is by design or there is a defect in my particular sample, but I sure am disappointed.
The next issue is that the charging USB cable that came bundled with the charger doesn't fit the headset tightly. It's loose and comes off easily, although the cheapo cable I bought from the 100 Yen ship works perfectly. Of course you have to charge both the phone and the headset simultaneously.
In addition to that, I have no idea what the power button is there for. It would automatically start charging when I plug in a device. I don't have to press the power button for that process to start. Pressing the power button would show up the LEDs to indicate how much charge is left, though I am uncertain is this is the intended behaviour. Pressing the power button again doesn't seem to turn it off either. The manual doesn't specifically say anything about this and it only indicates – in a diagram – that it is the power button. I'm lost.
Finally, the body of the case is very susceptible to scratches. Luckily I haven't scratched mine yet but I feel that it is just a matter of time. Going with one with an Aluminum body was a very bad idea.
All in all, I'm not too impressed with this purchase. The hassle I have to go through to charge the headset is a deal breaker. Therefore I have decided to return it to Amazon. I have few days before I can return it for a full refund. In fact, last night I applied for it and I have 10 days before I can return it. That won’t be an issue, but this means I can search for a new gadget to buy. Fun times!
