    Involvement Level: Expert (understands the inner workings)

    Pros: -Cheap -Only 1 operating mode (I like it) -small footprint, its easy to fit into a case

    Cons: -High working temperature -Current regulation is not very good. -The wires that come with the unit are too thin -Only 1 operating mode (for those who like more options)

    Other: I have some reservations with this product, but it is cheap, so I'll give it a try. If you want a cheap driver that works, this is for you.

    Involvement Level: Expert (understands the inner workings)

    Pros: ++ One mode. + Very easy to install + Presoldered wires are nice, i didn't even cut them + Cheap

    Cons: I can't see none. Probably someone would want more modes, but i like the only mode very much.

    Other: I would recommend that if you are looking to upgrade your multi mode flashlight into single mode one, or if you are just repairing an old and damaged circuit board. The price is good. The board itself is very simple so, there is not much to go wrong with it.

  • Great value driver

    posted by mervin82 on 19:30:55 G6T 19/06/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Well-priced is probably the best pro about this product! Buy it in bulk and it is even cheaper. Despite the low price, it works as advertised with no flashing, low/hi function. Also received the item in less than a week.

    Cons: The driver size is 16.7mm, not a big problem if you can file it down to 16mm.

    Other: Buy this driver if you do not need gimmicky modes, but a cheap single mode driver with 1 watt output

    Involvement Level: Expert (understands the inner workings)

    Pros: Exactly as described, just dropped in, runs an x-re r2 perfectly well, long run times. I am a novice when it comes to electronics, but found it easy to use. I have some other cheap torches that i am thinking of upgrading with this cree board.

    Cons: Could be slightly brighter but that would compromise run time. Not really a downside, more of an observation.

    Other: Buy it! Worth a go at the price, nothing to loose!!

    posted by Josh101 on 19:22:13 G3T 12/03/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: A good small driver for your projects or repairs. The output is relatively stable, but if your looking for a good driver go for these.

    Cons: Was shipped in a plastic bag, as a result one of the two I ordered was damaged. A chunk was missing from the Inductor, but it still worked. Not the safest but... Wires are on the small side and bending them too many times will cause them to snap. New wires can be soldered on.

    Other: If you need a cheap driver why not?

  • Decent driver

    posted by mundaire on 09:44:28 G3T 05/03/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Decent, though I would have preferred the connecting wires to have a bit more 'substance' to them.

    Cons: No instructions came with the unit, so best be prepared with a multimeter to double check the circuit before you get out your soldering iron!

    Other: Cheap & effective boost driver for anyone looking to convert/ build a AA or 2xAA flashlight. I'd recommend it, so long as you know what you are doing!

  • cheap boost converter

    posted by dingran2009 on 00:15:14 G3T 01/03/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Very low price. Use it for cree Q3 light, and works fine. Eyeballing it is brighter than old dead board.

    Cons: Generate a lot of heat with 14500 battery. No idea how long it will last or if it is better than old dead driver.

    Other: Cheap and works! I found most drivers for AA/14500 die pretty soon with 14500 batteries. 500 charatersssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss

  • Smallest Boost Converter i could find

    posted by Hexacat on 10:46:54 G12T 08/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Cheap and small Boost driver. Output seems regulated only between 1,8 V and 3 V, output current is ~600mA, output Power ~1,7W. Efficency was about 70-76%.

    Cons: Not realy regulated outside of the operating range. Also does not work regulated with higher Output voltage.

    Other: Measured it with a Cree XM-L in the Lab (4x Agilent 34401 for Input and Output Voltage/Current and Tektronix TDS220 for the output Waveform) Maybe you can find my Tables in the Customer Photos

  • Excellent 1-2 AA/AAA driver

    posted by relic38 on 19:38:36 G12T 05/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - Good boost driver for 1 AA or 2 AA/AA cells, may be too much current for 1 AAA. - Small, fits in some AA flashlights - Will run up to 4.2V, unregulated (even 4.5V, but gets rather hot) - Simple resistor change to adjust output current

    Cons: - Unregulated above 3.0V. Drive current is determined by the LED used and any resistance in the circuit. Can be a problem for low wattage LEDs.

    Other: It's a no-brainer if you are looking for a driver up to 3V (2AA). It may not be the best Li-Ion driver, since it is unregulated at that voltage.

  • good driver for two AA or Lithium-ion

    posted by yrnkrn on 03:29:09 G12T 04/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: While this driver works from 1V to 4.2V, its efficiency is terrible when voltage is lower than 2.4V. This problem is common with such drivers, as I noted on my review of SKU 128084. Also, current is not really regulated outside the 2-3V range (noted correctly in the description). I measured this data: http://i50.tinypic.com/3517qt5.jpg

    Cons: I ordered three boards, one arrived short circuit due to bad soldering of the black wire. I fixed it.

    Other: good driver for two AA or Lithium-ion
