LVFAN Extended Power 4000mAh Charger Case, Rechargeable Protective Charging Case with Micro USB Input/Output Port for J3 6 J3 V (Black)

I guess you have to grade this case with a curve. IF you want a higher battery capacity, this is a solution, IF you want a lighter, thinner design, this is going to confuse you. I like highest battery capacity on all my cell phones. I just bought a Samsung Galaxy Sky S320VL for Tracfone use, and happily this case fit, and all cut-outs lined up OK. The first case I bought had a missing internal USB connector rendering it useless, so I returned and ordered a second after finding out there wasn't any other brand battery case that would fit my phone. So it's true the USB connector on this case is the weak link in the product, careful, careful. ** FYI: The two put together -- phone and this case do fit inside of this belt holster I bought here on Amazon recently: For Samsung Galaxy Sky S320VL, HEAVY DUTY RUGGED Canvas Vertical AGOZ Case Holster w/ Metal Clip, Belt Loops, Velcro Closure, Card Slot & Front Buckle Clip So for now all is well. The included USB charging cable plugs into the case's USB connector and then passes through to the cell phone's connected USB connector, so both phone and battery case charge at same time, so you don't have to remove phone to charge separately. This case does add thickness and weight to your phone, but that's what it has to do to add battery capacity to the attached cell phone. 3.5mm phone jack lined up on my case, so all went well, with all the different "Samsung Galaxy..." designated cell phones they offer, it's tough keeping track of exactly which phone model we all have.THIS REVIEW is especially for this above Newdery Battery Case and the Samsung Galaxy Sky S320VL for Tracfone.

I am actually using this with the verizon samsung eclipse j3 so it isn't an exact match but pretty darn close. I had to remove the backplate of my phone to make it fit and drill a hole for the headphone jack but otherwise I'm very happy with my purchase. The battery pack doubles the thickness and weight but I prefer the feel of it. Definitely get a finger ring when using this case, just in case you begin to drop your phone. The battery lasts usually 2 charges from 30-40% phone battery for me so I'm very happy as I play quite a bit of Pokemon go.

The best alternative to extend battery usage! I have tried several batteries that never really met my expectations until I found this workaround. If you don't mind the extra thickness it adds to your phone, you will like this option. No issues with it affecting the phones microphone and no special charging cords required. A home run in my book.

Doesn't fit. holes don't line up, and doesn't recharge phone. I think it isn't meant for the J2

great buy,can keep my phone charged for 5 days with out outside charge.

Very good product

Form factor wrong for Samsung J3 eclipse. Functions fine otherwise.

Works great!

materiale conforme alla descrizione e di buona qualità. Unico difetto che ho riscontrato è che con il cavo usb si caricano sia la batteria del telefono che quella del power bank, ma NON funziona più come cavo trasmissione dati. per scaricare foto (ad esempio) devi togliere il power bank e attaccarti direttamente al telefpno...

Tarda mucho en cargar, se calienta mucho, no consigue caegar la batería del movil completa, partiendo de un 20% apenas lllega a cargar hasta el 80%. El conector no lo reconoce el pc y lo tienes que desmontar vada vez que conectas al ordenador. Se me ha partido el conector de la batería. UN FIASCO DE PRODUCTO NO LO RECOMIENDO. 30 € a la basura.

It was very nice to finally find a quality option for my older phone.
