Has a lot of flaws. Lengthy read....

So I have run into some major flaws in the two I have tried. May be a bit lengthy of a read below, but it highlights and explains the flaws I discovered. Pros: Stays cool when charging. Works well enough with an Anker portable battery pack, but kills the portable after two uses(which requires a 10hr charge on its own) Has 3 settings for different charge speeds. Now to the Cons; the first device I received would not turn on with some of the wall adapters I had, until I found one it would work with. On the third run charging batteries, I noticed it started power flickering on and off, so I unplugged and checked it over. Discovered the usb connector began melting on the inside, which is where we had previously noted a slight dimple in the plastic piece inside the connector part. I reached out to Customer Service and they immediately sent out a replacement. ((Thank you Liion Wholesale for the amazing turn around wirh Customer Support!)) But the debacle doesn't end! The replacement I had received, had almost the same issues with wall adapters and not wanting to power on or stay powered on. I tried different plugs, etc.. nothing. I tried my portable battery pack until payday to get a new 2.1a wall adapter to try. It worked well enough on the portable battery, but it would not turn on with a brand new wall adapter! Out of curiosity, I tried the cord that came with the new adapter. Surprise, surprise, the device powered on, cycled its lights, and it waited in stand-by mode. (Felt like it was mocking me at this point) But with the OEM cord and same adapter, it either refuses to power on or it would turn on *Very* briefly and immediately shut off. Received the replacement on Tues, by Friday night, I was ready to be done with the shenanigans the device was throwing at me. We got this to replace a Nitecore D2 that we used every day **reliably** for well over a year until the cable port itsself came loose. (Constantly shuffled and even knocked off counters a few times, it had been through it, thankfully not loaded with batteries). We thought we would save a few bucks on the Enook and score with a four bay charger compared to the D2 two bay at a higher price, but this has turned into a royal headache. I don't know if I am just that unlucky to get two dud Enooks or what. I reached out to Customer support on the weekend, and I am hoping I can just send them back and get a refund or credit to put towards a new Nitecore. **Also minor complaint in comparisons, the slides for the batteries are extremely tough, to the point of excess. I am careful when putting in and removing my batteries, but this Enook sent them catapulting across the counter a few times before I could react.

Works good so far

Have only used it once to make sure it works. The plastic casing isn't as thick as my Nitcore but it's ok as long as it works.It's a good price and time will tell so that's why the 3 star rating I gave.
