emergency charger led light

http://www.goldengadgets.com/led-lights/led-flashlights/high-power-led-flashlights/2200mah-portable-usb-cellphone-charger-with-1-watt-led-flashlight.html E1320 like it a lot. I brought 3. Better price than at Manafont http://www.manafont.com/product_info.php/8in1-emergency-power-station-for-mobile-phones-flashlight-function-p-1774. And it shipped from La, CA. Even after sales tax, it is cheaper than from China. Less wait and better price. Just hope they come OK.(First time order from them)

That's a pretty good price.

Yes even for us in CA with tax and shipping, it still come out cheaper. We will see how fast it reaches my door.

When someone buys this charger / light, could you post whether the battery is replaceable or not. I see from the specs it uses an 18650 battery. I just want to know if it comes out.

Thanks!

I original bought one but found it so useful I bought six more and kept a total of three of them for myself. I wish I got them for the cheaper price.

The battery is replaceable but you need to use a short unprotected battery. Protected Flames are to long unprotected Flames fit fine. I have been using unprotected Panasonic 2350s. The battery that comes in the charger is junk so find some short 18650s and stock up.

There is a hidden mode that allows you to charge devices at 1 amp instead of the standard .5amps. Hold the power button down until the 4 LEDs that indicate remaining battery power will flash in a two by two sequence indication you are in the 1 amp charging mode.

I can recharge my standard Motorola cell phone 3 times or a smart phone on the 1 amp setting twice. It will also charge anything that has a USB plug like an e-cig or an emergency weather radio. This thing was invaluable when we had the recent 4 day power failure, that is what prompted my to buy five more. The flashlight also works good it puts out a good amount off flood and you can use it as a nightlight in any unused USB port when the power is on. Also once the power is restored plug it into any powered USB port and it charges the 18650 battery inside the device.

Great deal on great device I highly recommend having at least one around.

E:

I've never purchased an unprotected 18650, could you recommend a source?

That light/charger looks perfect for travel. I could have used it this week on my Cincy trip when I forgot my iPhone charger cord. Just pack it in my briefcase and forget about it.

Thanks for the post, okyeung.

You can get unprotected Flames from Manafont, DX, Dino Direct or others. Callies Customs has some really nice unprotected Panasonics. Those are the 2 brands I trust and use I am sure there are others but I won't comment on what I haven't tested.

Here is a link to some Unprotected Flames they are getting hard to find. If you use these in a direct drive light be careful they deliver 5 amps.

These are very similar to the Panasonics I use I am not 100% sure they fit but they are unprotected and should fit so don't order a bunch of them until someone confirms they fit.

I use protected flames in my emergency charger. I have to squeeze it in there a little bit. But no damage yet.

I didn't try forcing one in since I had a bunch of shorter batteries, it's good to know they work in a pinch.

Has anyone tested the internal battery charging. Does it charge properly (i.e. using CC/CV and completely cutting off at 4.2V or under)? Does it have effective overdischarge protection?

Cheers

I ordered one from GoldenGadgets after seeing the original post in this thread, and it arrived today. It comes in the nice carrying case shown on the DX product page, but not on either the MF or GG pages.

Battery was at 2.29 volts(!), too low for my Imax B6 to let me charge it, so I put it on the TR-002 for ten minutes, after which I carefully gave it a slow 0.5A charge on the B6. Discharge result: 1377 mAh to 3.0V @ 1A.

A protected TF flame fit just fine, though I needed to put a piece of paper over the positive spring to be able to slide in the battery. Once in, there's still about 0.5mm wiggle-room, so how well (and whether) other flames fit will come down to tolerances.

The LED is claimed at 75 lumens, and is similar in brightness to an iTP A3 on high, so the claimed brightness is at least realistic. The head unscrews easily, allowing removal of the TIR optic and enabling candle mode.

Works fine as a charger, though I don't have any gadgets requiring the 1-amp mode. No-load voltage is 5.30 volts; with no load, the charger shuts off after a few seconds.

Update: With the supplied battery charged to 4.18 volts by my B6, its display switched from "charging" to "full" in about two seconds. After I drained the battery to 3.99 volts, it then charged it back up to 4.14 volts. Current measurements afterwards show a weird result: while the display is showing the animated "charging" indicator, current to the battery ranges from 8 mA down to -3 mA, cycling in sync with the number of lit LEDs. Once the display switches to "full", with all five LEDs lit, the current remains at a constant -3 mA. So it seems that the charger technically never terminates, but instead starts slowly draining the battery until the voltage drops to the point where it will switch its display back to "charging".

Since the device uses a soft switch, I also checked for parasitic drain, which registered as 2.5 microamps (specs say less than 5). Turned on but with no load, it draws 9 mA until it shuts off again after a few seconds; that's basically the drive current for the five LEDs.

Update2: Over-discharge protection works fine, and is in fact quite conservative. The last red LED in the battery gauge starts blinking rapidly at 3.30 volts, and it shuts off entirely at 3.12 volts. Of course, since the shutoff happens under load, letting the battery rest a while lets it recover enough voltage to eke out a bit more before a renewed low-voltage shutdown.
