We have already shared to you about Samsung’s official wireless charging cover for the new Galaxy S5, if you haven’t read it, you can check it out here. If you want a cheaper solution and don’t mind using third-party peripherals for your Samsung Galaxy S5’s wireless charging needs, you can get a wireless charging card instead.

wireless charging card for samsung galaxy s5

Getting a wireless charging card over Samsung’s wireless charging solution is quite a good cost cutting solution without sacrificing much, if any, at all. These wireless charging cards can simply sit on top of the Galaxy S5’s battery and connected to the right connectors for your device to have wireless charging capabilities.

Having the wireless charging card in your Galaxy S5 does not affect any of its connectivity such as NFC and Bluetooth, which is a good thing to know. The card is also extremely thin that it wouldn’t even seem like you have it in there, which some wireless charging covers sacrifice for more protection.

One of the drawbacks though is that it, if installed improperly, it might interfere with the Samsung Galaxy S5’s water resistance. Since the wireless charging card is very thin this problem is highly unlikely to happen, nonetheless it’s still a possibility, so when installing the wireless charging card, be sure that it is installed correctly. You do not want to find out that you placed the wireless charging card wrong while your phone is playing around with water, so do take caution.

Take note that this is a Qi-enabled wireless charging card, any Qi-enabled chargers will work as a charging source.

There are a couple wireless charging cards already available online for the Samsung Galaxy S5, choosing a reliable model might be a bit difficult, we have found one here available at the last week of April for less than $30.

Which one do you prefer to use, a wireless charging card or back cover?

  1. The qi charge card used with the S5 keeps the phone awake forever in a continuous loop. The phone stops charging at 100% then the qi transmitter shuts off then the qi reciever is re-discovered by the transmitter and the phone wakes to charge but then stops again because the battery is already full. This process repeats forever and the phones screen never goes to sleep, it makes the charger connected noise every time it connects, and the phone gets quite warm. The samsung official model qi charger system has NFC which supposedly solves the problem.

    • Has anyone found answer to the continuous wakeup? Put one in our two yesterday, work great but since they were charging on nightstands got to be a pain,

      • Hi Robert,
        As far as my experience with Samsung S4, the continuous wakeup will always remain a concern as the charger cover or card is an add-on. For the add-on, the transmitter cannot communicate accurately with the Receiver and vice versa, to stop charging once battery is 100% charged. However, Lumia 920 (which has built-in Receiver set-up) communicates with the transmitter as soon as its charged 100% and shuts down the transmitter.

  2. In my experience lots of these cards are based on Texas Instruments ICs which internaly are based on a active rectifier and a LFO. This LDO gets very hot when the receiver coil receives up to 20th from the transmitter. When the receiver card has to deliver 5 at 500mA then there are up to 15th to dissipate. This results in up to 7.5 watts which gets converted into heat.

    So some of my devices logged battery temperatures up to 60°C/140F. Im not sure if it’s healthy to cook LiPos to such high teperatures

  3. Sorry – this stupid add overlay went in between and I pushed the send button accidentialy…

    The water resistance is the second important part.

    Do in my opinion these cards are nice to have but are no replacement for a good solution tested and delivered by the manufacturer.

  4. I bought a qi charger for my last Gs4 Active. It did make the back cover bulge out and was very noticeable in the hand. The main problem was that the waterproof catch could not stay locked with the qi charger in place. Therefore, when I tried it in the pool, it leaked and phone was destroyed.
    However, the convienience of using wireless charging is huge. I would rather the phone manufactures scrapped waterproofing, in favour of stock wireless charging. All those fiddley charging covers are a huge pain.
    Keep working on it guys 🙂

  6. I’ve used a < $10 Qi card in my S3 for 2 years. No problems. Use whatever case I want. Doesn't bulge out if you buy the right one that is thin enough.

    I have a Qi charge pad on my desk at work and since I'm up and down all the time it is easy to pick up and put down without having to remember to plug it in. Is always 100% when I leave.
