The main difference between this unit and the DSD charger is that the UltraFire has two separate charging channels. This is a huge difference as you can now safely charge two batteries with different capacity or charge state.

On the downside, this UltraFire unit does require a spacer to charge CR123A and CR2 batteries. It is not available yet but it will be here soon. For now, a piece of a metal (such as paper clip) can be used as a spacer.

** Report on recessed contacts: Customer Ron reported that the positive nodes of the charger is overly recessed into the top of the unit causing problems charging some 18650 batteries and a workaround for this is to bend a paperclip and use it as a filler between the node and your battery. In the meantime, the Ultrafire 18650 batteries charge fine with this charger as is.

Pros: Great charger. It charges everything it says it will, and no fear of it having any issues.
It charges my protected and unprotected batteries without any problems at all.
You can not beat the price for this item on any other website.
Thanks geal extreme!
 
Cons: There are absolutely none to report on this charger at all.
It charges at a slower rate than some of the high dollar brands, but for the price I can wait the extra 30 minutes or so.
 
Other Thoughts:  
Bottomline: If you are looking for a charger that will give you peace of mind then this is the one.
It performs the same as some of the top leading high end chargers.

Pros: Reasonable quality at a reasonable price. This charger is very easy to use and has an auto-off feature, showing when the batteries are fully charged. Works with both 110 and 220 volts.
 
Cons: Build quality isn´t the best, but it was what I was expecting for the price I paid.
 
Other Thoughts: None.

Bottomline: This isn´t an excellent product, but it´s well worth the price and gets the job done.

Pros: Polyvalent est ça plus grande qualité. Jai acheté ce chargeur avec 2 packs TrustFire Protected 3.7V 900mAh 14500 Lithium sku:03435. Aucun problème depuis. Charge sans problème plusieurs type de batteries 3.7 li-on. Charge mes 14500 en un rien rien de temps !
 
Cons: Il est vrai que les emplacements horizontaux ne sont pas raccordé sur le circuit imprimer. Ca ce fait aisément avec un tuto donner dans un autre review.
Ces emplacements aurait pu être pour des cr123 de 3.0V
 
Other Thoughts: Ne pas charger des li-ion de 3.0V avec !!
 
Bottomline: Personnellement je n ai pas besoin des petits emplacements

Usage Instructions

Insert one or two 3.7V batteries to charge. Since the device has two isolated channels, you can simultaneously charge two batteries with different capacities.

An official ultrafire spacer will become available soon as an add-on. In the meantime, you may bend a paper clip to charge CR123A/CR2 batteries.
