I get several full phone recharges out of a set of four AA batteries, as compared to about one 85% charge from the Eveready® Energizer® Energi To Go™ Instant Cell Phone Chargers charger (although I suspect that the energizer was eating my batteries if I left them in there for more than a day.)
This unit does not discharge batteries no longer how long you leave them in there, so pairing it up with low self-discharge batteries is beneficial. You'll forget you have it until you need it!
VIDEO REVIEW TRANSCRIPT:
This is the TekCharge MP1550 mobile power supply and battery charger. This unit allows you to transfer power from standard AA batteries to USB power, and also will allow you to charge rechargeable AA batteries From USB power in an emergency.
This allows you to carry emergency power for cellphones, mp3 players, or anything else which can be charged from a USB port or cable. The maximum output voltage is 5v. You can use either standard alkaline AAs, or use rechargeables to power the unit.
The device is very small and compact, only a little larger than the batteries it contains.
The device comes with a charging cable and several interchangeable tips. The retractable cable on mine arrived frayed to the point where I don't think I could depend on it to work when I need it to. You can see the stray wires poking out from the wire sheath.Read more ›
This charger uses 4 AA batteries, and can also be used to charge 4 rechargeable AA batteries. You can charger the AA batteries through the provided USB cable, then in turn, use the battery pack to charge your iPhone the other devices compatible with this charger. It serves a useful dual purpose.
Also, this is a true battery charger, not a battery extender. It actually charges the battery so you do not have to keep the charger connected to the device to use it. I would recommend this product to anyone who needs a portable USB charger for their devices.
The power unit will work as designed and will be reliable if you do not exceed the limitations of the device. Again for emphasis, do not exceed the limitations of the device and it will serve you faithfully!
(There is a Summary at the end for the main highlights)
1) Overloading the Tekkeon
Do not attach a phone or any device that will draw more than 800mAh (.8 Ah)! Yes, this means some of those Android phones with giant screens, Dual Core Tegras, etc. If your phone draws more than 800mAh it will overload the little Tekkeon and burn it out sooner or later! It was not meant to supply power for those super power hungry devices. Know the electrical specs of the device you intend to attach to it!
2) Charging rechargeable batteries in the Tekkeon
Do not attempt to recharge partially charged batteries! It very briefly touches on this in the manual and yes, they should have addressed it more. With regards to charging batteries, it appears that the Tekkeon is a simple timer charger that sends a given amount of current for a fixed amount of time and then shuts off.
If you try to recharge partially charged batteries, the batteries will get full too quickly before the Tekkeon turns off. The batteries then shed this excess energy through heat. Solution: only charge empty or near empty batteries. You should be using a smart charger (like the La Crosse BC9009 or Maha MC9000) to recharge partially charged batteries.
To be safe, I rarely use the Tekkeon to charge and instead use a smart charger.Read more ›

It dies. It's simply useless to use for anything bigger than a Bluetooth. Contrary to people who said it would work with an iPhone it will not. An iPhone draws 1000' mA. Read morePublished 4 months ago by MSC
