Apotop Wi-Copy
Examination:
The Wi-Copy is a bit smaller than the size of a 2.5-inch SSD drive, for easy comparison purposes. At just six ounces and coming in at less than three inches for its longest size, the Wi-Copy is easily transportable if you're looking at using it for a USB battery charger or for mobile WiFi hot-spot.
The Wi-Copy uses a built-in, rechargeable 5200mAh battery that should be able to provide up to 14 hours of a continuous charge, according to Apotop.
The LEDs on the top of the device indicate charging, SD/SDHC/SDXC card activity, WiFi connectivity, and power.
On the front of the Apotop Wi-Copy is a USB port for attaching any external storage devices along with the SD/SDHC/SDXC card slot. The only downside of the Wi-Copy for Linux users is their file-system support of FAT16, FAT32, exFAT, and NTFS. EXT3/EXT4, F2FS, or other Linux file-systems are not supported for attached memory storage devices. From the front USB port is where you can charge any USB device after sliding the switch over to the battery/charging mode.
On the back of the Wi-Copy is the micro USB port for charging the device along with an Ethernet connection if using the device as a WiFi router. The device itself is within a sort of rubberized plastic case and felt quite sturdy if you intend to keep this in a backpack or briefcase.
