“Dad! Do we have another USB charger??!! The batteries in my calculator are dead and I need it for homework!” 

Sound familiar to you? I think I hear phrases similar to this once or twice a week in my house. There never seems to be enough power sockets. Just prior to wiring this review, I checked my daughter’s bedroom and found four single-socket USB chargers crowding two wall sockets, powering her phone, Bluetooth speakers, TI calculator, and portable power supply. She even unplugged a lamp to accommodate the charger she needed for the calculator.  I guess she would rather do the math than being able to see what she’s writing. Priorities, priorities…

Enter Syncwire’s SW-AC01 four-port USB charger. This powerhouse provides a generous 6800mA, or 34 Watts, staggered across two 1 Amp and two 2.1 Amp USB Type A sockets. There are no cords included. Measurements are 2.5 x 2.75 x 1.75”, not overly large, but certainly heftier than your standard iPhone wall-wart. For reference, if one were to assemble four iPhone adapters into a cube, it would be about the same dimensions as this adapter.

On a recent trip to South Carolina, I simultaneously charged my phone equipped with a monster brick backup battery, my daughter’s phone, my iWatch, and a Bluetooth headset.  It was a pleasure to pack a single supply, rather than a gaggle of gadgets. I was thankful the SW-AC01 sports folding two-prong plug, making it easy to toss into a backpack without worrying about damaging the plug (been there, done that).

International adapters are included. Syncwire’s implementation of these plugs is innovative, not requiring the built-in Type-A “American style” plug to be deployed to attach the international adaptor of your choice. Very clever.  This means that unlike many comparable models, the SW-AC01 does not need a separate adapter and stays considerably tighter to the wall. This is safer, sturdier and helps prevent accidental unplugging. Several years ago, I had this occur while in Italy and I assure you, it’s a very uneasy feeling knowing your phone battery is near death with a full day ahead in a country where you don’t speak the language and Google Translate is a necessity to prevent from tipping a cab driver so much that he can retire.

I’ve noticed a trend lately that manufacturers are cutting costs by not including power supplies with the devices they sell. It only makes sense to have one (or more) of these useful USB supplies handy. Syncwire’s SW-AC01 fills the need for additional power, saves on the crap I carry, and returns several wall sockets to me, restoring my ability to scold my daughter because she’s trying to read and it’s too dark in her room.

  2. Appreciate the review but frankly in 2017 USB charging devices that don’t deliver 2.4 A on EVERY USB port are just old fashioned. I hate to get my glasses on just to figure out which port I need to use.

    There are TONS of better chargers (at similar price points) that are smart and deliver the required amps on every port.

    For example here the Anker 40W 4 Port charger ($25) which provides 2.4A at all ports for a total of 8A. They also make one with high rate chargers for those Android folks – only $5 more.

    Yea, they don’t have universal AC plugs but that’s really a limited case and you can easily buy a plug kit (and you probably need one anyways if you’re going overseas).

  3. Just in case you are coming DownUnder the international plugs are just EU, UK, US it seems. So no good for Australia or NZ and some other places without an extra adapter.

  4. This charger by Syncwire is ETL certified and this is clearly shown in the box and the charger itself.
    I don’t have a USB port tester to test the output voltage/amperage, but the charger draws 20.3W at the input when connected to my smart outlet.
