2.0 out of 5 stars Great Idea, Poor execution., February 2, 2012

This review is from: Tekkeon MP1580 TEKCHARGE Mobile Power Pack and Battery Charger (Wireless Phone Accessory)
This product is a great idea but sadly the quality of this manufacturer's attempt is lacking.

First, the case is all plastic. The picture looks as though the silver strip might be metal but it isn't. This isn't necessarily all bad but the plastic they used feels very light weight and cheap. It is not solid feeling at all but rather is the kind of chintzy plastic feel you get with stuff that soon breaks from light use.

Second, and most importantly, it does not work with my Android phone. I purchased this for use specifically with one device and it just will not work with that device at all. I'm not sure exactly what is happening but it appears that there might be some type of communication trying to take place which goes wrong somehow and the power pack shuts off and stays off until power is cycled. If the output of the unit is shorted momentarily drawing excessive power it will shut down but then immediately recover as soon as the short is removed. I also measured the current used by my device and it is about 770mA which is well with in range. So the problem is not simply my device trying to draw too much power.

Third, it gets hot and shuts off even when not overloaded. I plugged another device in to the power pack and began to charge it. After a few minutes I noticed the LEDs on the power pack were out again. I switched it off and back on and it started working again but a short time later it did the same thing. I measured the current load of this device and it was around 750mA which again is well within spec. The unit was quite warm to the touch.

I first attempted to use the power pack with some NiMH cells but it seemed to keep shutting off from low battery when it was under load. I then used a set of fresh alkaline cells for all the tests above.

I would really like to find a quality implementation of this idea.
I really need one that works reliably.

Thank you. I am not the only with this problem. It appear its a hit or miss. Some users are saying it works why others like yourself describing exactly what happened to me. I had mines replaced twice, and ended up getting a refund instead. My phone is a blackberry bold 9700. The AC adapter draws 700mA, which is well below the limit for this mobile charger. I used the cable that came with the charger, using the microUSB adapter. My phone would charge for few seconds, and then turns off. However if you only use 2AA's out of 4 it will start charging but would make a buzz noise, and the moment you put the other 2 AA in the unit. The unit shuts off. So clearly, either their first batch are defective, or has a major design flaw in the circuitry. I dunno. I have their older model Tekkeon mp1550, and works just fine using the exact same cable. So its definitely not the phone, or the cable. Its the Unit!. I would stick with their older model for the meantime until this issue has been resolved.

Try it with different USB cables. Mine one does not worked with the Motorola stock cable. I bought a cheap one from China and it works like charm.

I have the exact same problem that other users have reported. Thank you for the advice to try a different cable; I gave it a try. This did not resolve the problem.
I tried three cables (all known good) and all manner of combination of batteries.

There simply seems to be a problem with [some of?] the units.
