+# Identify your device
+
+There are basically two versions of the PortaPack. If you have one that looks like the one below, you have the H1.

+
+The H2 is a slightly improved version, but the people making this copy never published the source, hence breaking the license terms. It looks like this:
+
+[[img/device_h2.png]]
+
+The main difference are the controls and the screen, but the H2 usually has extra circuitry to manage the battery charging and powering on/off.
+
+# Power on/off
+The original H1 powers instantly when you plug a power supply to the USB port. To turn it off, just unplug it. Similar to the issues with some USB cables while [upgrading the firmware](Update-firmware), the quality of your cable might affect the performance. 
+
+To power on/off the H2, you need to hold the middle button (knob or pushbutton) for few seconds. 
+
+# Extra functionality (H2)
+## Charging
+This version can charge the internal lipo battery via the USB. There is a led indicator that turn off when the charging is done, but it might flicker. 
+
+## Battery life
+A internal battery between 1000 and 2000 mAh should last a couple of hours of use, depending for how long you are transmitting. The standby consumption is [very low](https://github.com/eried/Research/blob/master/HackRF/PortaPack/h2_standby_consumption.jpg), around 52 uA, so you do not need to worry to remove/disconnect the battery in normal circumstances.
