The keychain sized Oittm Pocket Sized Charger comes with an Apple MFi certified magnetic Apple Watch charger. Apart from the usual charge feature the charger can also store 700mAh of power. One can simply connect any microUSB charging cable, and they will be good to go.
Oittm Pocket Sized Charger uses MCU management to protect the Apple Watch from overcurrent, electronic quantities detection and thus ensures the safety for your watch. Since the wireless charging dock is portable one can do without the long Apple Watch charging cable. Also since the powerbank can be charged using the standard microUSB and with this you will no more need to carry the Apple Watch charging cable. However, the Reserve Strap doesn’t come cheap at a staggering $249.99, and the product is currently suspended since Apple is yet to resolve the issue of blocking third party accessories on the Watch OS 2.
