I purchased this on 2/26/2019. Within a couple months, the force of holding batteries in part of the charger - but not the other - twisted the cheap plastic chassis and it cracked. I taped it to prevent further twisting and it continued to function fine. That was, until today. Like some other reviewers, I now have an issue with the spring in the first slot. I had a battery sitting in there, untouched and charging, when I heard a loud snap. The spring inside has either broken or detached, and now the first slot of the charger is pointless. I won't be buying another one of these.
I wanted a good charger that could charge a variety of types and sizes of batteries. After asking around and researching chargers. I purchased the XTAR Dragon. It was pretty new at the time and I paid double what they are selling for now. That being said I can rest assured that if I am not around and someone puts a battery in to charge it that it adjusts and charges it. I like a lot of the features this offers, plus I know that it has the ability to do stuff I haven't tried yet. I am happy with this charger, it seems to do it all.
Large enough to charge 4 26650 batteries at the same time. Refresh function is nice to have, takes quite a while though. It also does not charge fully. It usually only charges to 95%. Then I can remove and reinsert the battery and it will then charge to 100%.
DON'T WASTE your hard earned doubloons on this pricey puppy. It's very cheaply made and if all you need it for is recharging various size batteries then almost any other charger will serve you better. Although there was no obvious damage after shipping or unpacking the unit, bay #1 lost it's spring-ability after about 15-20 battery recharges, being preceded by poor polar contacts. The three remaining bays functioned correctly, although all bays were heard or one felt the grind of each respective spring against the plastic infrastructure with each extension and contraction. Believing that a simple realignment and attachment of the spring in bay #1 would solve the problem I gingerly opened the unit only to find that not only was the spring off it's turret but the turret top had broken off. Additionally, of the seven small screws that held the bottom plate to the unit, four of them had their screw columns completely severed at the base plate level. That being said of it's construction, let me now relate to it's electrical functionality. As far as I am aware, the electronics worked as described but having to hand hold a battery while applying leads to it's poles and simultaneously changing/pushing buttons on the charger in order to check battery voltage is not my cup of Dragon Grog. Just for that reason, I avoided using this charger unless I had multiple charges (2) that I needed to complete quickly at the 2 amp setting. Of course when charging more than two (2) batteries, the unit defaults downward to 1 amp or 0.5 amp input but it doesn't default forward to 1 amp or 2 amp input if charging 1-2 batteries only. One must manually increase the amp input by pressing a very small inconspicuous red button or otherwise wait the extended amount of time for the charge to complete. I also dislike the fact that since there is no unit on/off button ( like most chargers) it's blue LED lights are constantly burning, reminding you the unit is active or alive, even though there are no batteries in any bays. I find that terribly annoying and although a piece of tape can help alleviate the distractive glow, I found unplugging the unit from the back more satisfying but burdensome. I suppose I should have contacted Liion about the issues I had regarding the poor construction as I described but they didn't build it. They only sold it. Thus, voicing my Dragon Disappointment via this venue will have to suffice. Buyer Beware.
Hi Trip - Thank you for your review. It sounds like your charger had a lot of issues before we even shipped it to you. We will be contacting you, via email, to resolve this issue and get you a replacement charger.
I've used an XTAR VP2 for 6 years or so, and it's still going strong. I knew XTAR would be a great option for a 4 Bay 'smart' charger, so I went with this Dragon. It came well packaged with a zipper case that holds the unit and all the accessories. The refresh features and such seem accurate and reliable. The battery slides are smooth as butter with a firm grab on my 14500's up to my 21700's and 26650's. The only gripe I have is that the red/green lights above each bay are ****** bright, and we're bothersome at night. This was easily rectified with carefully applied pieces of electrical tape.
