When I looked at the specs at first, I was in disbelief. A 30w usb-c charger… I needed exactly that. And this ~20000mAh size was exactly what I wanted. I wanted this to charge both my laptop and my iPhone at fast-charging speeds. I did not need quick-charge, but that was still a plus. "SmartID" was useful for legacy iPhone charging (before iPhone 8, as the newer iPhones charge slightly faster via the USB-C port). Finally, I found the lightning-in port to be a major plus for charging the device, as I have dozens upon dozens of lightning cables.
I preferred this device over most other similar chargers as it does not include a micro-usb port. Those can sometimes get unnerving, considering how few micro-usb cables I use. The lightning port is very convenient.
After the purchase, I took a closer look at the specifications. All ports exacted my expectations, except for the lightning port. I found the issue to be that the lightning cable charged too slow. I know 10 watts is near the 12 watt ceiling for lightning, but the unit is still >17% slower than what it could achieve via standard iPad chargers. Another cool, but niche feature would be if the lightning port allowed for 29 watt charging (input) like on the iPad Pro models (so you could charge the iClever portable charger very fast like with USB-c). Sadly, I expect few people would/could take advantage of this, so the only real port flaw (if even a flaw) was that the lightning port could not charge at 12 watts.
The flashlight feature I found interesting, and potentially useful. However, given that iPhones have much brighter flashlights than the on the charger, I found the feature somewhat redundant.
What I loved about the device was the USB-C port. It is simply amazing to charge *and* discharge the unit at 30 watts from a single port. This is one of the best uses of USB-C I’ve seen to date. I love it! This is exactly what USB-C was made for! I have seen some other chargers match this design, but it does not discount how convenient it is for consumers (such as myself).
The battery indicator button I found could get difficult to find when the portable charger was not plugged to anything. However, I am not sure if there is a better place to put the button. I like the black color that blends with the surrounding black case, but sadly this makes it harder to find the button itself in certain cases.
So far, the only technical issue I’ve had with the charger is that the charger does not automatically charge any device. This is not an issue; you simply have to press the indicator button, unplug, and re-plug your cord into the portable charger. Though I can see this as a potential positive in some cases, it is not convenient when you leave something charging... but then you realize it wasn't charging. Besides that, I have had no negative experiences with the device whatsoever. The charger charges very fast no matter what you throw at it. The 30 watt USB-C port does not seem to charge as fast as marketed, but this should not cause too much of a difference. This could also be a fluke in my cable... I have not professionally tested it.
Overall, I rate this a 5/5, simply because it fills a certain gap in the range of portable chargers. It is not like any other portable charger. It takes on a new niche in the portable charger market. A niche, especially for Apple fans, wanting to charge both their phones and laptops (like the Macbook) simultaneously, while being able to charge the charger with already-existing lightning cables. This device is tremendously helpful for me.
