Product review: Parall Ultra-Slim Wireless Charger Portable Charging Pad

I have been using Qi chargers with Nexus 5 for over a year. I love the technology, it is convenient and does not stress the micro USB connector by constantly needing to connect and disconnect it. I own several Qi chargers and through experience found several features that make some Qi Chargers work better in day to day use than others.

➀ Speed of charging

Some charger charge my phone faster than others. Speed is always important to me. I compared charging Nexus 5 with Parall Qi Charger to the same test run with the other chargers and found that it was one of the fastest. It charge the phone 7% in 10 minutes. I run the test at the same charge level, running the same apps, and keeping everything the same for an "apples to apples" comparison.

I also measured the charge rate with a current monitor. The current monitor showed ? A, which was again among the best.
current monitor: ~~~~~ 1.21A and 5.05V (Excellent)

➁ The size of the sweet spot
This is an area where the charger did not perform as well as the others. It has a very small sweet spot. I show this in the video for a better illustration of what I mean. I show both the phone on the charger and the current monitor which shows the rate at which the phone is charging. When it is perfectly aligned it draws an optimal charge. If the phone is moved a little bit the charging drops from an optimal rate to lower rate, and when it is moved a little more it draw no current and then the charger turns off. So if you accidentally brush against the phone and it moves it may stop charging. This is particularly important if you have small kids or pets who may touch things.

➂ How well the phone stays on the Qi charger

The phone can be easily knocked off the sweet spot of the charger unintentionally. The charges that handle those unintentional bumps best are the ones that have non-slippery finish. Parall has a very shiny and slick surface. It looks very nice but not ideal for creating friction. In addition the size of the charger is smaller than Nexus 5 which it slightly harder to align it perfectly.

My trick for charging on the go: When I need to charge the phone on the go (i.e. when it cannot lay flat) I double wrap a rubber band around the phone and the charger. This keeps the phone on a sweet spot charging in a pocket/purse. I like it better than having a micro USB connector which can be damaged if the phone/battery are jarred. The rubber band trick works very well with this Qi Charger because it is square and thin.

➃ How easy it is to see that the phone is charging

I like being able to see a visual indicator that the phone is charging. If the phones stops charging I like having a quick way of telling this without having to look at the phone charging status. Nexus 5 is 5.43" x 2.72" x .34" in size, Parall charger is 4.875" x 2.25" x 0.25" so Parall is smaller than Nexus 5. The indicator lights are faily large but can be seen only if I look under the phone.

➄ Is the battery using standard cables

I like the chargers that use a standard micro USB cable, so I don't need to worry about losing a special cable. Parall uses the standard micro USB cable. Excellent!

Bottom line? I thought it was good. Its thinness and shape makes the battery work well with my rubber band trick and that is very important to me for charging on the go. The charging is speedy. The small sweet spot is smaller than I like and requires extra attention to make sure the phone is aligned well.
