Re: How many chargers have UL Listed Symbol ?

TMG, I understand your concern and was not trying to be a smartass about it. I only ment that you will not see to many of these low voltage DC devices with the approval, why I don't know. I too expect to see it on all devices that connect to line power. It may be that the wal-wart that has a UL rating may have the needed protection built into it and they don't feel the need to get a UL approval for the secondary device that it powers. I have looked around the house at different wal-wart powered devices and have found that most only have a CE rating on them, this includes; camara docking station/charger, cell phone, printer, scanner, cordless phone bases, cable modem, wireless router. The only ones I found with a UL on both the wal-wart and the device where the laptops, and the video cam.
I understand the concern may be greater with the use of Li-ion batteries, but then do the batteries themselves need to be UL approved, after all they can be just as bad as the charger or the device using them.
Just my thoughts, and I don't mean to sound rude. :)

Re: How many chargers have UL Listed Symbol ?

Hi there,


Let me get out my paintbrush so i can get my home designed chargers
UL approved :) I think i know how to paint that sign.

Actually, if it's run off of a wall wart (and mine all are) they dont need
UL approval.


Take care,
Al

But the "wall wart" does have to have "approval" (check the ones associated with your PC's and note the Regulatory "marks"). The National Electrical Code (NEC) states that anything that connects to the AC mains MUST have approval by a Nationally Recognized Test Lab (NRTL), of which UL is only one, theer are several. The DSD charger, of which I also have one, does not have any approvals at all. I use mine, but I never run it overnight or without at least casual monitoring and I run it on a ceramic tiled surface....just in case.

I went to radio shack last night and found low current / nominal 300ma chargers for 3, 4.5, 6, 7.x, and 9 volts, but not 5.5 v like the DSD charger uses. They also had a mult voltage supply - with the same settings. All of them were around $ 20 each.

Any suggestions for a UL / CE / CSA (any of them are ok with me) wal wart ?

Hello HarryN :

The Nokia ACP-12U (800ma output) that I got as an option from AW when I got his DSD .....does have UL symbol stamped into the plastic of this power supply .

CAUTION : you can not use it when you're charging cells rated less than 800 mAh ........such as a RCR123 (750mAh). according to info from 'AW"'s sales thread.

Hello again,


I didnt mean to imply that the wall wart *itself* didnt need to be
UL approved, i just meant that the charger didnt need it.

I like the ceramic tile surface testing idea...i might actually do this myself.
I almost ruined my counter top one time testing a partially bad switching
wall wart --> plugged it in and *poof* a resistor smoked completely spewing
out black soot that stained the pure white counter top! What a mess,
and lucky i was able to clean it up, but there is still some off color
spots that wont come off at all due to the short burst of high heat.
Too bad i didnt think of the tile thing.
Lucky for me the spots arent too noticeable.


Take care and thanks for the idea,
Al

Does anyone know what these other 2 symbols represent ?

One is a small square inside a larger square, the other in a house figure with a arrow pointing into it.

I would guess the second one means inside use only?

Re: How many chargers are UL safety certified ?

willchueh said:
Two UL standards (depending on configuration of chargers) can apply:

UL 1310
UL 60950

The second one focuses on information technology equipment (whereas the 1310 is a broader, more strict requirement). Typically battery-specific lithium ion chargers for digital cameras/camcorder use this standard.

All Maha chargers sold in North America carry UL and cUL (Canadian) mark tested under either standard. There are two ways to submit the chargers for testing. One is to submit just the AC portion (for chargers with external AC adapter, this will just be the adapter; for chargers with integrated AC, it will be the whole charger of course). The other method is to submit the whole charger system (adapter + charger, if they are separate). Generally speaking, UL will not list a DC charger by itself as it is not explicitly covered in the scope of the two standards mentioned.

Here is a brief summary on Maha chargers sold in North America:

Charger+Adapter System Certification (UL logo printed on charger & adapter):
- MH-C204F/GT Series: UL 1310
- MH-C401FS Series: UL 1310

Charger Certification: (UL logo printed on charger):
- MH-C204W: UL 60950
- MH-C801D: UL 1310
- MH-C808M: UL 1310
(Note, for 801/808, the "AC Adapter" is more than just an AC adapter so it is considered as a charger).

Adapter Certification (UL logo printed on adapter)
- MH-C1090F: UL 1310
- MH-C490F: UL 1310

Many of our international models (like the MH-C204W) also carry regional cerifications such as:
- European Safety Mark (typically GS)
- Australian Safety Mark (typically RCM)
- Singapore Safety Mark (PSB)
- Argentina S-Mark
- CE
- Korean eK Mark
- China CCC
- Mexico NOM
- Japan PSE Mark


cheers,

William

Some of the MAHA chargers were not found as listed when I searched the UL website. I was specifically lookinig for the 808m model.

Here's a link to the UL website. http://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/index.htm

Morelit: The doublesquare mean that the electricity details has a double isolation and they don't need a ground contact, they fit in both our wall sockets here in sweden.

I don't know if you have two different wall sockets in US but here we have.

I hope you understood my explanation:whistle:

Sorry for my english.

(This explanation stood on a electricity site here in sweden, i hope it's the same for you in the US)

I don't have the answer to the other one.

Hello Bp044,

The difference is that the AmondoTech unit comes with a 12V adapter, charges AA cells at 700 mA instead of 500 mA, and has a 14 hour shut off timer instead of 11.5.

dayton oh
too many china crap products have forged ul/ce/csa/vde/ect logos on them.
if its unusually cheap to buy and cheap looking/feeling/crudly made its likely dangerous junk.
had a customer who called me onsite to help deploy 150 pc's
they bought these goofy looking usb hubs for each.
i got halfway through the rollout when several users complained the hubs wouldnt see their usb drives.
long story short several of the wallwarts smoked,buzzed,and a few melted and caught fire.we immediatly collected all these hubs to send them back.
i opened a few wallwarts and found they were very shoddy inside and the main filter cap after the bridge was a 100mfd at 100 v.when they see 160-170 they were blowing up.
no fuse in there so the electrolyte caused unlimited arcing on the ac side.
the wallwarts had every logo imaginable on it.
all fake.if i were to inspect these i would have ordered the whole load to be destroyed and landfilled!
