Client Critiques
The charger has a fixed plug for North American outlets. The input is rated 100-240VAC, 50-60Hz. The output is rated four.2VDC, 350mA (it is about 4.6VDC open circuit). There is an LED that lights dark yellow throughout charge, and green when charge is full and when no battery is connected.
The LED truly starts to become a lighter yellow when the battery reaches four.1V, a lighter yellow-green at four.15V, and is green at four.2V. If you only charge to 4.1V, you will get even more cycles but if you charge to four.2V, you get a longer flight time - it fundamentally averages out.
In the course of my testing, this charger only put out its rated output on incredibly discharged batteries and just for a minute. It is normally only placing out about 250mA after five minutes, with the battery at about three.87V. The battery will reach 4.1V just after about 40 minutes. It takes one more 15 minutes to reach 4.2V, which may give you an added minute flight time.
So you can see why I am a small dubious about many people claiming that this charges their battery in 15-20 minutes. If accurate, I have to assume their batteries are old and only give a couple of minutes flight time. I normally get about 7-8 minutes.
Still, this will charge the battery 20-40 minutes faster than the USB cable charger, and the LED gives a trustworthy indication of when the battery is filly charged. I am only giving it 3-stars mainly because the output is weak (which is quite possibly fantastic for a single 150mAh battery - I use 2 in parallel for 300mAh, with a 1.five hour charge time, and a 15-16 minute flight time), and it would be nice if the voltage was restricted to 4.2V to minimize overcharging the battery.
I also measured the USB cable charger. It puts out about 250mA max, and the open circuit voltage is about 4.6V. The battery reaches 4.1V in about 60 minutes, and four.2V in about 85 minutes. The USB plug will begin an occasional dim blink at about 3.93V and 35 minutes a dim glow/blink at about 3.96V and 40 minutes and a dim glow at about three.99V and 45 minutes. The glow will get brighter as the voltage increases. Following about 2 hours, the battery voltage is 4.3V and climbing.
With either the wall plug charger, or the USB cable charger, considering the fact that they each have an open circuit voltage of 4.6V, I can only assume the battery will maintain increasing in voltage until the safety circuit in the battery cuts off the charge. This may perhaps ultimately shield the battery from failure, but is nevertheless not fantastic to charge LiPo batteries more than 4.2V. Do not leave the battery on either charger for extended periods.
This charger is terrific. When I charge with the USB it takes about 1hr. This charger cuts it down to about 20-25 minutes. This truely lets you use your helicopter additional. Well worth it and a fantastic addition to the S107
