Power Bank benchmarks

This is a personal test for 5 different power banks that I buy:No brand 2200mA power bank

  • ROMOSS Sense 9 25000mA;
  • TP-LINK TL-PB15600 15600mA;
  • EC Technology PB-EC001 16000mA;
  • MediaRange MR751 5200mA;
  • No brand 2200mA.

This test here all done with:KCX-017 USB Power Meter

  • To meter the consumption I use a power meter KCX-017;
  • For charging Charger 5V, 3A;
  • For discharging I use a tablet Chuwi Hi10Pro (Android and Windows 10 tablet) that charges with a USB charging (playing YouTube HD/Full HD videos to drain the battery).

CHUWI Hi10 ProI’ve tested 5 different power banks, 4 of them Chinese (ROMOSS Sense 9, TP-LINK TL-PB15600, EC Technology PB-EC001, and a simple powerbank with a 18650 battery) and one german (MediaRange MR751). All were tested with the same KCX-017 USB meter and add the amount of 20 mA per hour of consumption in my measures.

When I was charging I use the KCX-017 to measure the Voltage and the current of the circuit with the same AC/DC power adapter that can give 5V 3A.

Testing PowerBanks

I’ve measured the time and the TOP power provided when I’ve charge the power banks and here is the results:

Final results and opinion:

romoss sense 9 power bankThe most efficient was the one with the highest capacity with almost 66% of efficiency (ROMOSS Sense 9). Meanwhile, the one who charges faster the equipment that it is plugged and charges faster it (capacity vs time) is the TP-LINK TL-PB15600 who makes the winner of these tests.

Unboxing and review TP-LINK HS110 (long test)


This was my first Unboxing and Review that I made. I’ve unboxing and test the SmartPlug TP-LINK HS110 with energy monitoring. I hope it will be usefull for you.


After 2 weeks of testing, I strongly recommended this product:


I recomend and give a 5 stars (5/5) for this product.

Samsung Gio (GT-S5660) CM9 – Android 4.0.4

Samsung Galaxy Giocm9After I try to update to CM11 (Android 4.4.2) and see that is not working properly (KitKat is too big for this phone) I decided to install CM9 (Android 4.0.4 IceCream Sandwich) instead.

First you need to know that with this process you will avoid the warranty for your device, and you will do it on your own… I can’t be responsible for the damage that it will eventually do to your device.

I tested in my old device that I brought in 2011 with success. Only the camera doesn’t work.


1 – Root your Gio With Gingerbread 2.3.3:
  1. Download: Update.zip
  2. Copy ZIP file to your SD-card
  3. Turn off your phone
  4. Now, you will have to switch ON your device in the recovery Mode which can be done by holding the Middle button and then Power ON the device by pressing the Power ON button.
  5. In recovery mode, you will see the option called “apply update from SD Card”, select this option and then you will see that the list of files will come from which you will have to select the file which is named as Update.zip
  6. Wait a few seconds (MAX 5 minutes!)
  7. Your phone is rooted


2 – Install ClockworkMod Recovery

The next obvious step after rooting an Android device is flashing a custom Recovery Image. A custom recovery not only helps you flash custom ROMs, but it lets you take backups of your current ROM so in case you mess up with your device, you can easily revert back to the working firmware. The widely popular ClockworkMod Recovery’s available for the Galaxy Gio and the guide below shows how you can install it on your device. Here you go:

  1. You must have rooted your device before doing this procedure.
  2. This will replace your current recovery with the CWM Recovery.
  3. Download the ClockworkMod Recovery CWM 5.0 v2 and copy to the Root (not in any folder) of your SD card
  4. Put your phone in recovery Mode(press: Home button + Power button toghether)
  5. In recovery mode, select the downloaded file “apply update from SD Card”(Use Volume keys to navigate and home button for enter).
  6. Search for the file downloaded “.zip” on your SD-card
  7. Run the update
  8. Reboot

You’ve successfully installed the ClockworkMod Recovery on your device and you should be able to flash custom ROMs and Mods right away!


3 – Flash a CM9 – Android 4.0.4
  1. From this page download the CM 9 firmware file. The password for rar file is www.androidpt.com
  2. Save the Android 4.0.4 OS (cm_9_final3gio-ota-eng.zip) on your computer – just place the file on desktop without unzipping it.
  3. Now, connect your handset with the PC by plugging in the USB cord.
  4. Then transfer the downloaded files from desktop on your phone’s SD card.
  5. Remove the USB cable; the computer is no longer useful.
  6. Turn off your Galaxy Gio.
  7. Enter your Android device in recovery mode.
  8. From recovery select “wipe data factory reset”.
  9. Now return to main menu of recovery.
  10. Up next you have to select “install zip from SD card” followed by “choose zip from SD card”.
  11. Select the cm_9_final3gio-ota-eng.zip; flash the update on your Samsung Galaxy Gio.
  12. Then from the main menu of recovery you need to select “reboot system now” and you are done.

Perfect. You have learned how to safely update your Samsung Galaxy Gio to Android 4.0.4 OS. CM9 custom ROM firmware has been installed on your Android device, so you are done for now. Just give it a try and test the new software.
