I got a hold of (from a friend) a AC->DC 5v 2a power transformer - it connects to the wall with lamp cord/ figure-8 connector, and has a USB plug on the other side.

I can't for the life of me find this (or anything like it) anywhere to purchase.

I don't even know how to search for it. I've searched by its Samsung model number, Amazon & Ebay for "power adapters", "travel adapters", etc. with no luck. Everything has the 2 prong wall plug connected to the actual adapter (trying to avoid the wall wart).

Does anyone have suggestions, or know how to find these? Do I need to make one from scratch?

  • \$\begingroup\$ If you can't find anything searching for its Samsung model number, smells like cheap Chinese item with the Samsung logo smacked on it for credibility. Have you actually verified its performance at 2A? I would guess it's questionable at best. \$\endgroup\$ – Matt Young Feb 25 '15 at 15:56

  • \$\begingroup\$ @MattYoung: If it really is the N10 charger then it delivers a nice solid 2A, but the photos are too bad to be sure. \$\endgroup\$ – PlasmaHH Feb 25 '15 at 15:58

    \$\begingroup\$ You specifically want an inline one, rather than a "wall wart"? \$\endgroup\$ – pjc50 Feb 25 '15 at 16:47

    \$\begingroup\$ @MattYoung I once bought a box of 10 allegedly "CE marked" chargers for $10 just to see. Not only did they not bother to fake the certification the casing could come apart in your hand. \$\endgroup\$ – pjc50 Feb 25 '15 at 16:48

Those are modular supplies. The connector where the figure 8 plugs in can take a direct plug, that has us or euro or whatever mains connector. By coincidence they also use the IEC 60320-1 C7 and C8 Figure eight connector.

This is done because it is cheaper to make one universal 120/240 power supply, and a bunch of physical adapters, which can then be paired as needed. Smart/cheap manufacturing.

One particularly well known oem who uses these type of adapters is Apple, for both laptop, tablets, and I believe iPhone as well. So a oem iPad charger will work like this.

  • \$\begingroup\$ In the case of the N10 charger (which might be that on the crappy picture) there is an adapter included which "transforms" this thing into a wallwart. \$\endgroup\$ – PlasmaHH Feb 25 '15 at 16:17
  • \$\begingroup\$ Is there no way to purchase these without buying a marked up Apple product? I'm trying to find something cheap/large quantity, and I don't want to manufacture these myself. \$\endgroup\$ – Nick Jonas Feb 25 '15 at 16:30
  • \$\begingroup\$ Is not a mark up, is the cost of a well engineered and safe and up to u.e. standards product. The cheap and knockoffs take considerably unwise shortcuts. That said, look for other manufacturers that use the same type of charger, or ebay clones. Or simply ask a manufacturer or reseller if they have a iec 60320 c7 connector version. \$\endgroup\$ – Passerby Feb 25 '15 at 19:10
