  • Works as it should

    Involvement Level: Expert (understands the inner workings)

    Pros: Charges as it should, seems to shut off after the batteries are full. No issue after about ten uses. No warming noticed on batteries or the device itself.

    Cons: None really, seems to work okey. Only issue was the US adapter, but bought an adapter for it.

    Other: Charges by batteries fine, been using it for some months now. No issues found so far, after about ten times charging various 18650 batteries from DX.

    Pros: a good charger for 18650 type batteries. it is build to do the job and decent quality. it can charge different types of batteries. it charges batteries fast.

    Cons: The first couple of times used it can produce a plastic smell. like a eletronic PCB board. it might be a bit difficult to get the batteries with protective pcb(sku20392) in it without scratching the top and/or bottom. it would be nice if they included a cable with or adapter with EU plug. i know you can buy an adapter but it would be nice to have it with the bundle

    Other: It is a decent charger that does what it should. it is a good purchase for the price. i have bought this with a flashlight and some batteries.

    Pros: Cheap does his job. It is possible to charge only one of the two cells. Also powerable from 12 volt.

    Cons: Gets very hot during charging. The plug head that comes with it is a 2 flat pins type....not suitable for my country. But I replaced the whole thing with a 2 pin round type, it works without any problem.

    Other: Cons is what you can expect with a charger for this price. Great charger

    Pros: Its a charger which will charge ur battery...Good thing is that it can charge many sizes. Red light turns to green when battery have been charged fully. I charged 14500 and 18600 batteries at the same time and it works. Great!

    Cons: The plug head that comes with it is a 2 flat pins type....not suitable for my country. But I replaced the whole thing with a 2 pin round type, it works without any problem.

    Other: If u need a cheap charger go for it. It looks great and does its job.

  • Nice charger that is worth its price

    posted by Finmale on 01:30:21 G9T 09/09/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: I have bought at least 10 of these charges and had never any problems with them. It is nice that you can charge also only one battery as usually only one is empty at a time.

    Cons: It could be a bit faster too, as now it takes a few hours to fully charge a 2500 mAh battery. On the other hand a fast charging usually shortens the lifetime of the battery, so this is not a real con.

    Other: Buy it and you wont be dissapointed. The rest that I'm telling you here is onlyl because they want me to write so many characters about farely simple prodct.

  • Good and effective charger for Li-cells

    posted by CoryV on 07:07:42 G8T 07/08/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Charger for multiple types of Lithium cells with two independently operating slots. Cut-off is just over 4.1 Volt, a safe charger for unprotected cells as well.

    Cons: The 12 Volt jack is placed on the side and is a little small in size. Inside, components are not well placed and the soldering is a little rough.

    Other: Overall, this charger is well worth the money!

    Pros: * It is cheap and does what is sholuld do. *Two independent unit so you can even charge two batteries with different capacity. * You can use external DC source at the side connector. This case the heat generated by the internal power supply that works on 240V AC (mains) can be eliminated. So the batteries under chargig do not get heated their life will be longer. * The power cord can be removed (changed) and you can use an other one with other type of connector (for example in Europe not the flat connector is the standard)

    Cons: Although somehow the CR123A type battery is on the list of chargeable ones and there are side (cross) places for them. What is suspicious: there are no marks for polarity (+ and -) this is because THESE CONTACTS ARE NOT CONNECTED. If you want to charge such short batteries you have two choices: 1, You introduce some pieces of metal (as an emergency solution a proper size ball of aluminum foil) to make them long enough to reach the contacts in the long part. 2, For ADVANCED players: You disassemble the unit (unscrew the upper scew (close to the AC socket) and the other one _behind the label_) and connect the unconnected contact with 4 short pieces of wire to the live ones. After you have done the soldering and the screws are put back connect it to the AC and check the polarity of the cross contacts with a voltmeter. Anyway the springy contacts are not so strong they surely will not push out the electrolite from the battery :)

    Other: It is ideal for longer batteries and can be modified for shorter ones.

    Involvement Level: Expert (understands the inner workings)

    Pros: I have always bought this charger together with sku 19770 and this charger seems to work well. It is good that you can charge also only 1 battery and it shows green light when the battery is full. This is maby not the fastes charger, but I think the batteries last longer when not charged fast with great current.

    Cons: A small minus is that here in Finland (and many other European countries) we have to also order the sku 03529 flat to round power plug converter.

    Other: Works well at least with sku 19770 batteries.
