Peeling off the Samsung Galaxy S3 from its protective case to charge it wirelessly defeats the purpose of convenient accessory use. This is solved by the $13 non-official charging kit for the GS3.

In a review by Gotta Be Mobile, the Chinese-made SainSonic GS3 wireless charging card receiver is desribed as a tool that powers up devices minus the spaghetti wires and use it at the same time when needed.

Once installed, the GS3 is instantly transformed and made compatible with charging pads that adhere to the QI standard, allowing users to place the phone on docks made for Nexus 4 and Galaxy S4.

Prior to that, the GS3 can be wrapped back to owners' preferred protective case and the card's charging performance is not downgraded a bit.

The energy card is available via Amazon though the giant online retailer currently displays the kit at $17.49 or $4.50 higher from the one reviewed by GBM.

Two big bonuses packed with the accessory is the elimination of a special back cover and the bulk that normally comes with wireless charging paraphernalia. This means buyers can enjoy the benefits of portable charging with style.

Use of SainSonic is straightforward. GS3 owners simply need to remove the phone's back cover and attach the receiver on top of the battery, securing the pairing with the supplied sticker.

It is important that the card is aligned with the battery as instructed by the manual for proper charging though the whole mechanism is further tightened in place once the back cover is popped back in place.

The fit is almost perfect, keeping the light and slim GS3 profile while the card is going about its normal function, the GBM review said.

As mentioned above, simultaneous charging and device operation is possible but optimal powering up is further realised by connecting the phone to power cord during charging time.

True to the advertised features, GBM confirmed that charging up is fairly quick, almost comparable when the GS3 is being charged up tethered to a power outlet.

Note that the energy card is not stand-alone. It requires the use of charging mats, which are sold separately with prices ranging from $60 to $100.
