Rated 4.0 out of 5 by 24 reviewers.
Rated 5.0 out of 5.0 by Meets expectations This helpful little gadget does exactly what it is supposed to do. I used it to charge my cell phone at locations where no outlet was available. It did not charge the phone to 100% but where it is written that it has to do that. Sure, there are devices on the market with better capacities but I bought this in a kit together with other TEK4 gadgets and it does his job. The best thing is that I can remove the battery pack from other TEK4 devices to charge e.g. my PDA or my cell in an emergency. This is not possible with other portable power sources. For this I give the full five stars. August 31, 2010
Rated 3.0 out of 5.0 by pretty good i like it, i use it. i have an iphone which i use the usb extension to plug in my regular phone charger. it mostly does not charge my phone up to 100%, i think it has once, but usually levels out at about 80%, which is better than 0% of coarse. i do really like the design, and look and the battery. i feel like im saving AA batteries.. very green. good to have always tucked away in the car, but i left the battery inside the device once and it drained itself of juice, i dont know why. but from now on i keep a battery and charger seperated in my glove box.

Rated 2.0 out of 5.0 by Thoughtless design. Why on earth would you put an outdated micro USB for the output on the device? it should have been a regular full sized USB output so you could plug any device's USB cable into it to charge. Yes, they included an adapter to go from Micro to standard usb, but mine lasted about a week before it got bent from sticking out and stopped working. Also, it would have been nice if it could output 5V at 1A instead of 500ma, since thats pretty much the standard now. Some inteligent redesign, and this could be a 5 star device. Holding Two tek4 cells instead of one might be an idea. July 30, 2012
Rated 5.0 out of 5.0 by Great Product! I have had this now for about a month and have used it several times recharging my cell phones when out and about and also have had fun charging my kids hand held gaming systems for them when we are away from home without their chargers. Everyone should have one of these with several of these batteries waiting in the charger at home to replace the used ones so you always have a fresh new battery waiting for you. I see all kinds of applications for this device and will definitely be buying another in the near future. April 30, 2011
Rated 1.0 out of 5.0 by Hope it works better for you! I thuoght this would be a great product for a back up for my Iphone,WRONG! I went through 3 of these before giving up. I don't know what went wrong but they quit working after 2 to 3 weeks. I love the flashlight. it works great, as well as the headphones my friend is using. I'm in a wheelchair and don't think I put more wear and tear then a construction worker. This "Tek4" brand is geared towords heavy usage, it fails horridly. I hope they can cure the problems, its a great idea. November 19, 2009
Rated 4.0 out of 5.0 by Design drawback I really like this product, however it has a fatal flaw and unless the manufacturer moves swiftly to solve it, it will not exist in a year because no one will buy it. The green adapter which is clearly the most important, as it accepts a regular USB jack, which many devices utilize. The adapter then goes to a flimsy metal part that plugs into the battery itself. This adapter is easily fatigued and broken and unless one purchases the entire set AGAIN they cannot get a replacement part. September 9, 2011
Rated 5.0 out of 5.0 by Bought 2 I'm surprised by that review, I got on here to talk about how much i love this thing. I bought one for my wife and she keeps it in her purse. She always forgets to charge her phone so she has to leave it in the car to charge when she's in the store and when I have to get a hold of her i can't. It used to get me pretty paranoid but now she can charge it in her purse and take her phone in the store with her. it's an awesome idea and it's a pretty inexpensive gift too December 7, 2009
Rated 5.0 out of 5.0 by WHEW!!!!!!!!!!!!!!!! Pressed for time and making calls from my cell that are out of this world. Have one last potential :"client"to contact when the cell says goodbye/ bleep, then silence. ( goes dead ). HOORAY for RYOBI POWER SOURCE, in which I injected its raw power source right out of/ from my briefcase, and, BAM- I am on the air-waves again and able to conclude my business. Thanks Ryobi- such a wonderful idea!! This is a MUST for ANYONE that puts their careers on the line using cell-phones. March 20, 2010
