Zanflare C4 LCD Display Speedy Universal Smart Battery Charger,Battery Capacity Analyzer for Rechargeable Batteries, aa Battery Charger, 18650 Battery Charger

The Zanflare C4 is Zanflare's entry into the Battery Charger market. The C4 is a 4 bay multi-functional smart charger which can charge and analyze NiMH, NiCd and Li-Ion batteries. The C4 is great for anyone looking to upgrade from their non-analyzing chargers. User Interface and Modes Each slot can operate completely independently (for example, slot 1 can be set to charge, slot 2 can be set to Fast Test and slot 3 can be set to Normal Test). In order to set different modes for each slot, you have to insert each battery one-at-a-time, set the mode and then wait a few seconds before inserting the next battery. Each slot can also have separate a current setting. The mode and current is set within 10 seconds of a battery being inserted. Operation: * When battery is inserted, press MODE within 10 seconds to rotate through the modes (Charge, Fast Test and Normal Test). * When battery is inserted, press CURRENT within 10 seconds to rotate through the current options (300/500/700/1000mA for Charge and 300/500mA for Test). 500mA is default. * Once charging/analysis has started, press the individual buttons (1, 2, 3 and 4) to rotate through the display for each slot. Modes: * CHARGE - Basic battery charge mode (300/500/700/1000mA) * FAST TEST - Discharge then re-charge and measure capacity (300/500mA) * NORMAL TEST - Charge, discharge than re-charge and measure capacity (300/500mA) Display: Each also has it's own individual display and can display: * mA - Charge/Discharge Current (Shows the setting, it does not fluctuate in real-time) * V - Voltage * mAh - Cumulative charge * mR - Internal Resistance * Time - Cumulative charge/analysis time Summary and Conclusion The C4 is a nice analyzing charger both in terms of function and appearance. It supports up to 4 18650s simultaneously and can charge up to 2 26650s simultaneously (non-adjacent slots). It can also support charging NiMH and NiCd so this makes it a good universal/family charger. It can also fit protected cells up to about 72mm in length although longer and wider cells like GAs feel cramped and tight. It does not support LiFePo or C/D cells. I like the charge and discharge current options (300/500/700/1000mA for Charge and 300/500mA for Test). I know that some people prefer chargers that can support more than 2A+ for charging or 1A for discharging. However, I prefer charging/discharging my cells at lower speeds for better longevity and less heat. I normally charge my 18650s at 500mA regardless of charger used. The 300mA charging option is also great for people charging smaller cells like 14500s. The charger has good size and ventilation and does not need a built-in fan. When charging 4 cells at 500mA, the charger gets warm. When charging 4 cells at 1A, the charger gets very warm (but not overly hot). If someone wanted to add cooling for heavy use, you could set this until on top of a cheap laptop fan since there are a lot of vents on the bottom. I like the display options and the ability to view actual voltage on top of accumulated charge. I also like that there is individual information for each cell so that I can monitor voltage for all 4 cells at the same time. However, I would prefer if the unit/interface was not "upside down" (design preference). I like that the unit is powered with a proper wall/car plug and not USB-powered. The sliders move well (not too stiff or too sloppy). The power bank functionality works well and charges my phone pretty quickly even on one cell (1A charge). Using cells as a power bank is also a good way to discharge cells (either for storage or testing) without "wasting" energy. My unit terminates charge around 4.16V and the voltage accuracy is within 0.3V when removing cells and measuring them with a voltmeter.

This is an excellent device! It's the best battery charger out there, in this price range...imo. I had a very basic charger before buying this; it basically charged the AA or AAA nimh batteries...nothing else. Plus, I could only charge either 2 or 4 batteries at a time. With this, I'm not limited. 1, 2, 3, or all 4 at a time. I finally NEEDED a charger that was more versatile & told me what I want to know about the the batteries. Well, this charger does it all really. It's great knowing the voltage, charging time, capacity, etc. No having to wonder about the status of the batteries you're charging! Very happy & impressed with this! Seems to be well built, & great quality. The display is very clear & easy to read too. I've been charging at 500 ma...& 300 ma, to be easier on the batteries. The default setting is 500 ma. I'm really into recharging my AA & AAA nimh batteries. Much better & really saves money. I was just tossing regular batteries in the trash can, which is wasteful in the long run. This is definitely the way to go! Thanks for making a great charger like this! Next, an upgrade on the battery tester I'm using. I know exactly the one I want too, from DIYlful. I included some photos. It really shows how consistent this charges. The Duracell did very well. I wasn't even aware they were 2500 maH. Nice.

I live this charger. I have bought more expensive ones, and it does not do what this one does. I tried to rejuvenate almost dead cells with other chargers, and they would not do it. I then put them in this one and used the NOR test, and vola, it brought them back to life. It does have three modes, charge, fast test, and NOR test. Charge does what it says, it charges them, and pretty good also. However, it does not rejuvenate them. Fast test..I used it but I don't think it has much use. Maybe to see what the current capacity is, but I think that it is better to use the NOR test. Nor test. It charges the battery, then discharges it to see what the rate is, wiping out any memory effects, and then charges it again. It does this for 3 cycles and leaves you with a full battery. I tested several batteries this way, and even though they said 5000 ma, they really were less than 1500. I tested brand new IMREN batteries, they said 3500 ma, and all were at least that, if not a little more. But all were within 5 % or less than what they stated. So now I know what batteries to purchase also. They are a little more expensive, but then you get two to three times the battery also. The display is easy to read for me, and the unit is easy to use. It says End when done. You can adjust the charge/discharge current. You also have a dedicated button for reading each of the batteries, not like other chargers that you must cycle through.

Awesome Units When I clicked Buy I thought I was Only Getting 1 unit But it was for 2 .. I have am using this to test/check 18650 Batteries and it works Well .. took a while to figure out the menu .. press buttons .. done .. Very Easy to Figure out..

Very dissapointed. For a universal charger, it does not charge D type or 9 vrechargebale batteries. and the USB ouput does not work with NiMh batteries. If you're hoping to use this in conjunction with high capacity 2800mAh NiMh batteries to charge your mobile device, look elsewhere. Overall, unless you want to specially charge lithium ion batteries, this is not the best option.

Excellent battery charges and testers. These are invaluable tools for use in cell harvesting and testing large quantity of batteries. NiCad, Nimh, Li-ion.

Facil pour la prise en main .3 charge 300ma 500ma 1A et 2 fonction de testeur normal et rapide je ne pouvais pas donne plus de cinq etoile

too big, lcd display need to be better
