I got 2 of these and neither would hold a charge. Meh sent replacements (thanks!) that I haven’t tested yet but I’ve never had very good luck with these single 18650 chargers. These are also very solidly glued together, a big hassle to pry apart if you are thinking of trying to replace the cell. So I’d hesitate to order this model again. All the other models I’ve tried so far have been fine, though.
If the Halo cylindrical version comes up I might buy and try. I have a similar one and it was much easier to open than the Mophie version.
Also the thin flat 3000 mAh Mophie pack, currently 2/$6 in this mehrathon, is quite nice, so I’d suggest that unless you really want the 18650 form factor.
