What do they have in common a iPhone 11, Samsung Galaxy S10 or the Xiaomi Mi Mix 3? All are compatible with the wireless charging. And they are not alone: practically all high-end phones (and some mid-range) have this feature that allows you to fill your batteries without connecting any cable. But you do need a charger specific for it, which none of them incorporates serial.

Finding an alternative is not difficult, since many signatures of peripherals and accessories have in your catalog with one or more models. The proposal of the Sandisk goes a step beyond simply filling your battery: why not take advantage of the time that is the terminal on the base to make a backup of photos, videos or contacts?

Size variable

So in the iXpand Wireless Charger has been exploited to integrate an internal hard disk —is available with two capacities, 128 and 256 GB—. To do this it has had to make some sacrifices in the design, which has to be larger than usual in this type of devices: 100,3 x 19.5 x 201,4 mm and 201 grams of weight. Despite its size, has attractive aesthetics that highlights your finish gummed, ideal for improving the stability of the phones that are placed on it and not end up on the table or on the floor.

For the backup function it is essential to install an application on your 'smartphone'

While to use it as a charger it is only necessary to plug it in to the outlet if you want to take advantage of the backup feature it is essential to install an app on your smartphone (it's compatible with iOS and Android). Through it enables the Bluetooth connection and Wifi to automate your operation, and also give permissions to maintain active location; something that we don't finish to understand, and that if you refuse, apparently has no impact on the operation.

The process takes a little time and we have to make sure that the Wifi network you selected is 2.4 GHz; if not, it will not work. In the event that there is no one of this type available, the charger generates its own network that allows you to continue using it normally. So, I just leave on a daily basis the mobile phone charging for gradually completing the copy of all the contents.

Multiple phones at the same time

Sandisk iXpand Wireless Charger can be used with multiple phones, as long when you have configured independently. All the management is done from the app I mentioned before, very basic to simple view: a drop-down menu with some adjustments related to the permissions of the app or the access password to the device, and the main interface displays the level of charge left in your smartphone or the free internal memory on it and on the charger, as well as photos, videos, and contacts copied. In addition, it allows you to browse according to the file type, file date, or restore you want and free up space on your mobile.

is Not the only way to access the copy, since it is also possible to do this by connecting the unit to a computer via USB. In the case of which is protected by password will be encrypted; you can decrypt through the software free Sandisk PrivateAccess.

quick charge

This in terms of its function as a device for performing backups. As a wireless charger we found with support for rapid charging up to 10 W, which implies that it is able to fill the battery of an iPhone 11 Pro, for example, in something over two hours.

When is active shows a light lilac in the front that can come to disturb during the night, as it does not turn off once the charging cycle, and it works perfectly if the phone has a cover (although yes, of maximum 3 mm thickness). In addition, it has function of detection of foreign objects, protection against overload and adaptive load to protect the battery from the phone. And if you place an object that is not a mobile (currency key) is disabled.
