Samsung Travel Adapter fakes

Wanted to buy original Samsung Travel Adapter with current rate 2A.
It turns out that is not so simple... because most of them are fakes on market even if sold as super original.

A dozen USB chargers in the lab
Tiny, cheap, and dangerous: Inside a (fake) iPhone charger

One I've ordered via Groupon.
Seller was some local site buy2: Genuine Samsung Charger, proposal was like on this page - http://www.buy2.co.il/o/7cf4afaf-1671-448c-a655-e8aefd5c9b68
I paid 59 NIS and wet to pickup it from Hertzliya.
When I came to the shop, I told that it looks like fake adapter: letters jumping. At home I've checked idle voltage, it was above 5.3V. So I've opened a case at PayPal (as I paid with them). Time passed, no answer from seller, PayPal returned me my money.





The second I bought from eBay, seller neq-trade from Germany. Listing not more exist after I opened a case for fraud item. ~57 NIS with postal delivery.

Look closely to the following pictures


On second picture you can see wry USB port.
And highlights from first one

Waiting for an answer from seller.
UPDATE (2014-07-26)
Seller send another picture of adapters he sell, that are also fakes because of wrong text on them.
END OF UPDATE (2014-07-26)

UPDATE (2014-08...)
Seller refused to admit that it was fake and I escalated the case to eBay review.
They did full refund on behalf of seller :-)

Now, let's look how original label should look like.

1. From Samsung shop in Netanya's Poleg mall, ignore model difference. Costs ~130 NIS (with cable).



2. From Bug electronics shop. Sells in original Samsung packaging, cost 89 NIS.
Perfect text alignment!


Update (2015-04-25)
One of fake adapters few days ago stopped working.
Let's openup!

Board connects to mains with this contacts.

That is already rusty!

Very simple design. Main components:
Top left - fuse 250V 2A
Caps looks good, holds capacity. Thanks that its rated to 105C, surprised :-)
DB1 - MB6F - diode bridge - tested, good
IC1 - DK112 - controller
IC2 - CDT817C - optocoupler
T1 - Transformator
D1 - RS1M - diode - tested, good
D2 - SS54 - schottky diode - shorted! need to replace, ordered on eBay


Typical application for DK112 (but 12V 1A power supply).

Some original boards I found on net below.


Left - original, Right - fake

012 Smile internet

Looks like now, my internet connection is fine.

After I've spent a lot of time last week on my cell phone with them, their VoIP box passed away, and they replaced it by new one after 2 days. Another fail is when I ask for free call back from support because I on my cell, they saying "wait, it will not take more than a minute" and then again and again.

All was need is a right support guy, his name is Eugene.
He is not tell to Cisco employee "type ping on black screen, it's spelling P-I-N-G" or "you need a PC technician, you have problem with your PC" that's just so unprofessional for support host. I guess, the main issue on any support service its experience and quality of that young boys and girls, 012 is the worst company.

Also, if 012 representatives (not support) promise to call you back on next day to check is that fixed or when to take replacement, that will never happen.

But anyway, thumb down for 012, better choose Bezeqint or Netvision.

012

I want to clarify why I complain about 012 and why you should avoid buy their service.
I'm not saying that it happens with all their clients, but from what I know - you better find another provider.

I work at Cisco and till April 25th 2010 our company was paid for home broadband internet, usually 5 Mb / 512 kb. I was happy subscriber of HOT business as infrastructure and Bezeqint Business as ISP.

Now, as company reduces costs and employees need to switch to self paid internet. Cisco called all ISP to the office and the come with different deals - 012 Smile, Netvision, Bezeqint and Orange. Most of us chose 012 cause of lowest prices. They have bundles (ISP + infrastructure) or just ISP service.

Compare details on 012 deal to Cisco versus regular request as new client, prices in NIS.
Client type: Business vs. Private
ISP cost: 30 vs. 90
HOT cost: 72 vs. 80
Bundle cost: 102 vs. 130
In summary, if you are new client you will pay 130 NIS every month for 5/512, if you from Cisco - 102 NIS. Pretty good prices for us, because we have a big group of people looking for internet.

Now, when I switched to 012 from Bezeqint, here start my problems.
The major are
- torrent traffic is shaped (more details in next post)
- L2TP connection lost from 2-4 times per day
- support is also playing ping-pong with you sending you to HOT, HOT to 012 and so on.

Before Cisco (3 years ago) I was also using 012 and was very unhappy with them because of same things. I thought they changed - wrong! Now they won't let me leave and keep fucking my brain every day (details to follow).

By the way, you can try them for 14 days and disconnect without even say a reason as new remark to law says.
