A quick note here, the Tekkeon is an small rechargeable, external lithium polymer battery. It goes hand in hand with the Cradlepoint routers, but can power other 5V devices, with its 25.9 Wh output power.

This past week, I decided I was going to check it out. In preparation, I placed the unit(s) on charge overnight. When I got to work on Friday, I attached the PHS300 to the TekCharge and powered up the router. I noted the time at 08:51. I admit the unit got somewhat light usage through the day, and when I powered it off at 14:52, the battery indicator on the Tekkeon had only dropped a couple of bars / lights.

After I got home, I fired it up again. That was at 17:37. I used the unit to continue to power the PHS300 and Franklin Wireless CDU-680 combo. My 17″ MBP was the only device using the wireless, but had more moderate usage while I surfed, ran some speedtests, sent some emails, and other general internet activities.

I hadn’t paid close enough attention, but somewhere later in the evening, I had exhausted the Tekkeon battery and the PHS300 was running on internal power. I turned the PHS300 off at 23:42, and disconnected it from the Tekkion in order to recharge the battery pack over night.

At 08:23 this morning, I once again powered up the PHS300. I left it disconnected from the Tekkeon to try and get an idea of overall total battery run time. The unit finally shut off at 09:39. This was after heavy use running Remote Desktop, performing server admin “stuff”, and other general internet activities.

All in all, it adds up like this:

This is a whopping 15 hours and 21 minutes of total use! That far exceeds what is advertised, and in my opinion might not be a true test, but it was realistic. I didn’t use the unit continuously, but in real world scenarios, this may be typical. For example, in a power outage, or for portable use, you likely wouldn’t be running continuously anyway. A larger issue would probably be your laptop battery giving up the ghost long before the Tekkeon/PHS300 combo.

The other item that may be different than your situation is my generally excellent RSSI. In the office, it varies, but is around -70dBm. However, here at home, I currently enjoy about -57 to as good as -51dBm. I also can achieve almost 2.7Mbps downloads with the CDU-680, that gives my 3Mbps DSL connection a run for its money. So the stronger signal, I’m sure, helps by requiring less power, and thus increases battery life.

All in all, I am thoroughly impressed with the performance. I’ll be looking to give the battery powered router another test, under less ideal conditions.  I’ll also devote some time to try and do a continuous run from power on to exhausting both the Tekkeon and the internal PHS300 batteries.

Certainly stay tuned for future updates.

Today, I did the first test of the new router on battery power. From initial power on, until the device shut off, it was a full two hours and forty minutes! Wow, the original device only got up to 2:20 or so, after I had cycled the battery three times.

Impressive performance. I looked to see if anything was different, but the router is set to broadcast at “medium” power, just as was the first one.

Maybe there really was something defective with the first one from the beginning. Time will tell, and I will report further as I continue to use the PHS300.

Decided to give it a try… Results are with the ACS “Internet Key”, and below, my “new” Motorola KRZR K1mb tethered to the MBP.

This result is using the KRZR (wow, 2006/7 technology comes to Alaska!) The download speed really isn’t bad, but sure wouldn’t want to have to endure large uploads at this rate. At least it’s easy to do, and the unlimited data and messaging plan with the phone is only $15.
