    • Super small and works perfect.
Review Image by B Franklin
Worked perfect for my cyberbrick controller. It takes 3 AAA which at a rechargable rate = 3.6v. It seems like the controller will work with around 4v or up. Soldered this inline with the battery pack and pretty solid 5v output, at least enough for a hobby project. The small size is a huge plus.

    • Works as advertised - may need a pull down resistor if application is "high" frequency
Review Image by Annette Davis
Review Image by Annette Davis
Works well, however it takes about a quarter of a second for voltage to fall off when boosting 0.8V to 5V. This can be fixed with a pull down resistor. I am using this to take a 0.8V signal and boost it to 5V so that an arduino can trigger off the 5V signal (input must be over 3V for arduino to read high). The thing I'm measuring rotates up to 6k RPM so I need a signal to go from on to off in a few milliseconds. The voltage would not fall off quick enough on this for the arduino to read low before the next cycle starts, so I had to add a 1k pulldown resistor between ground and the 5V line so that the voltage falls off quick enough. Now works great with this addition. Nothing is getting noticeably hot. I haven't ran this for any meaningful time so no telling if it'll last, but so far this is a cheap simple solution to triggering arduino with low voltage levels. ... show more

    • Worked for 1S lipo, for RC receiver + 2 sub micro servos.
I purchased this to use with FlySky receiver and 2 tiny sub micro 5g servos. boosting voltage from 2.4 to 5v. It did indeed boost the voltage enough to power the RC receiver. However, it could not power the servos when trying to step up from only 2.4v ( two NiMh batteries ) the servos would not move and the voltage dropped from 5v to 1v when trying to use the servos. This booster is only rated for 480ma. However, using it with a 1S lipo at 3.7v worked just fine.... it is only rated for 480ma so technically my RX and 2 servos may draw more than 480ma but it worked fine on a 40 minute test. For low power applications, it seemed to work well, at the right price and great low weight ( good for RC planes ) at only 1g. However I will probably look for a similar light weight booster rated for 2 amps, as I'm worried this one is rated for only half an amp. ... show more

    • Really Tiny 5V Boost Converter, Very Low Power Operation Possible
I bought these to use with 3.7-4.2 V lithium ion batteries for projects where I needed 5V to run older electronics, specifically liquid crystal displays (LCDs). They are really tiny and easy to add to even the smallest project box. They have a significant current capability, but all of my applications are in the battery-operated, micro power range. Without an illuminating LED, most LCDs are in the sub-milliamp range unless updated at high rates. This boost converter uses a small inductor to generate a voltage above the input voltage. By themselves, these controllers draw a minimum no-load current of a few milliamps. I added a 2.5 mH hand-wound toroid inductor to the input wire to augment the inductance on the board, along with a 100 uF capacitor on the output for noise filtering. This dropped the no-load operating current to a fraction of a milliamp. That allowed using the LCD with about a milliamp of added current draw to the battery. There are probably a lot of other applications for these that involve higher currents, but small size and the possibility of very low quiescent current was why I bought them. ... show more

    • Great boosters
All 5 boosters worked just fine. Tested them as a Joule Thief with a green LED and 5.1K series resistor (draws around 0.5mA at 5V) as a load. All boosters managed to turn the LED on with as little as 0.52V on the input. And the maximum draw on the input was about 7mA which happens when the input voltage is on the low end (0.52V). At higher input voltages the input current to the booster is lower. ... show more

    • Small enough to fit d-cell flashlights
I use these to boost the voltage on several d-cell flashlights when used with led bulbs. Tight fit but it can be done.

    • Easy to use and they basically work. HOWEVER - Very inefficient.
I used these devices (I am not using them any more) to take power from an 18650 battery and generate 5V for target devices. They are super-simple to use (just 3-wires), and they worked well out of the box. The 5V is stable and clean (add a few caps, downstream, of course). They are not at all efficient. Best case, when the input voltage is 4.5V+ (fully charged battery), they yielded about 84% efficiency. However (and this dramatic a drop was surprising to me), the efficiency drops as the input voltage drops. With 2.8V going in (like when a battery is nearing exhaustion), the efficiency is 44%. Around 2.8V they get a little wonky and won't up-convert voltage much below that. So this means that as your battery drains, the efficiency drops, requiring more and more power from the battery to satisfy a constant load, for example. It's an accelerating cycle that drains the battery really quickly. That's too bad, since these are tiny, easy to deploy units with a relatively clean output. They're kind-of battery killers, though. Modern DC/DC converters should be able to maintain 90%+ efficiency over their full range of input voltages. For non-battery powered applications where power does not matter, or your load is very, very light, and all you need to do is convert a voltage between about 3V-5V to a stable 5.0V output, they'd probably be OK. ... show more
