Review of COOLSELL double sided micro USB cable


I bought a few of double sided micro USB cable from COOLSELL. I’m not sure they have any patent for making this, but it is little bit expensive than normal micro USB cables.


It is really easy to plug to any device to micro USB port, sure it is works and charges over 1A. So I have to check with USB power current meter and my battery exhausted LG GPro to charge in 5V 2A power supplier.


All COOLSELL cables charged my phone in 5V(+/-10%) 1.3~1.4A. Maybe not works as over 1.8A means LG GPro protecting over current in minimal battery state. So I have tested with Xiaomi micro USB cable, again.


It seems almost same with COOLSELL. V and A measured as same, and there’s nothing at any problems. Good molding each end of cable – USB and micro USB ports, and coated with fabric material may increase durability but decrease softness and bending.

Price may almost 2 to 4 USD with difference of length. I was bought one 30cm and two of 120cm with different colors. Comfort to plug any side, it is really lovely.

I hope price going down for more, to buying more in under 10 USD, but I think it is little bit expensive than other sellers.

COOLSELL 3 in 1 USB Charging Cable


I bought a cable from AliExpress for charging my many devices from one power source ( mostly portable battery ) and it arrived in 2 weeks later.


My oredering option was 50cm for carrying easily. Cable provides cable tie for easily carrying in my pocket or bag.


This cable support 3 different ports: iOS lightning, micro USB, USB-C at once. These ports are used in both for charging, not for data transfer – Don’t use it for data transfering at two or three devices.


Specially micro USB cable is not as similar most of one sided. It is supporting both side to be charged or data transfer in any side you want as like iOS lightning cable or USB-C type.

Now I tested 5V 2A charger with this cable. Stand-by voltage is mostly 5V 2A and upto +10% ( max 5.5V 2.2A ) in charging. Measurement used Keweisi (it also from AliExpress) USB power checker.


Actually I don’t have USB-C type device, so I tested with my wife’s iPhone6s and nVidia Shield tablet for how many current loaded from charger.


But it seems not for fully supporting quick charge at 2A. It only loads around 5V 1A current. It seems double sided micro USB port not supports over 1A power current as next test for only charging nVidia shield tablet.


It checked as real charging current load as under 500mAh. So I changed cable to other for charging loads.


As checked result, Coolsell 3 in 1 USB cable is not supports 2A charging speed. It is little bit negative feature for fully supporting quick charge. But it will be nice for price consider unsder 5 USD per unit and supporting multiple device charging from one power source as like Xiaomi battery.

I will use it for my Xiaomi 1000A battery for charging my iPhone and Android devices. But could not be recommened for supporting quick charge.
