I am in little confusion between these two models, as both are from single manufacturer, but price differs as ECO6 is quite low cost.
Which one is better? Say your view and also put some review if you own any of the two!!

never used or seen much of the ec06 but lots of people do use the imax b6 . i have an imax b6 pro .

@gurudutt wats ur budget ?

@Shauvicks: no, I have a ECO6 already, but somehow I got an info that IMAX B6 is superior to ECO6. I checked the HK website and found that both are having same specification, so I posted here to know from the IMAX owners in this forum about those extra features which makes both the price differ around a 1K.
ECO6 is around INR1500 whereas B6 is around INR2500.
Budget does not matter, but this review can help beginners as the single battery charger is helpful for entire range of batteries.

@gurudutta the best and cheapest for beginners is

or

really good performance i have both of them

@Shauviks: The second charger you mentioned is NOT so good. The charges at something around 500mA - that's too low. But, yes, at that price, it's a good buy.

Oh the topic is diverting, no doubt the post by shauvicks contain good one to begin with, but if one will buy a eco6 or b6, all the ranges of battery are covered, so no need think about charging while buying battery!!
And also no one is telling the extra features in B6 which makes it costlier!!
