◆ Appearance check
Legion Meter arrived at GIGAZINE Editorial Department.


A brief description on the back.


Legion Meter main body was in silver package.


Legion Meter body and instructions only.


The manual is written in English.

When Legion Meter is inserted in the USB port, the logo "LeGioN" appears on the display, so if you wait for a while, the voltage (V) will be displayed.

If you quickly press the action button on the display screen of the "LeGioN" logo that appears immediately after attaching LEGION Meter to the USB port, you can use the USB port on the right side without any problem because you can flip the display display upside down.


◆ I measured the charging time
Experiment at Legion Meter to quickly increase the charging speed. This time, we used the USB 3.0 port which corresponds to the output of 1.5 A maximum on the left side of Let's note CF-SX 3 as the power supply USB port.


First, let's charge the iPhone 6 without Legion Meter. The time it takes for the discharged iPhone 6's battery to charge to 99%3 hours 59 minuteswas. This number will be compared.


· Apple mode
Next, charge Legion Meter to Apple mode and start charging.


Always charged at more than 1A.


The results of charging five times in total are as follows. The fastest time · the slowest time The average time for three times that cut two time is about2 hours 12 minutes. Therefore, compared with the case without Legion Meter, "Speed ​​up by 81%It was the result that it was. It does not go up to 92% of the maximum value, but using Legion Meter seems to make a difference in speed overwhelmingly.

In addition, because it was 2 hours and 25 minutes because I used LEGION Meter while keeping the screen ON with the maximum brightness state, it seems that it can be charged at the explosion speed even when the screen is lit up.

· Android mode
I tried charging Nexus 5 in Android mode. After charging in Android mode, somehow by the end of charging4 hours 17 minutesAlso to the result. If you charge directly from the USB port without using Legion Meter3 hours 45 minutesIt was a shameful result that it is slower to use Legion Meter ......

As shown in the picture, Nexus 5 can only charge at 0.5 A or less, so the speed is not up.


I thought that Android mode might not work, I charged it in Nexus 5 + Apple mode4 hours 20 minutesAnd it was almost the same result as Android mode. As I suddenly felt it, I tried charging iPhone 6 in "Android mode"2 hours 08 minutesCharging is complete with. It was questionable whether switching between Android mode and Apple mode was meaningful ... ....

However, as I tried charging with Nexus 6, I always kept over 1A, so the explosion effect of Legion Meter seems to be fully demonstrated.


Although it may not be effective on some terminals, Legion Meter is able to say that it can be said that it is a very useful tool for people who smartphones are charged frequently from PCs, because they can increase the charging speed of smartphones almost twice. is.

Legion Meter can be purchased at the time of article creation from the following official website at $ 39.99 (about 4700 yen).
