Review: Trustfire TR003P4 Charger

ow that's a lot slower than expected, but as long as it's a good charger i can get over that!

First battery is charged after 9 hours, put it in my KD C8 and wOWOWOWOwowowooot!

The light i owned before seems to put out 75 lumen max if i compare to the low of this light, just sick ... and then i still have a NW dry coming up :o

Thats very nice of you Chicago. Have you ordered anything from manafont yet? I just opened a new account through the same link and it didnt indicate that the referral was successful.

Trustfire TR003p4 15.19 usd (13.67 usd with coupon "DINOGIFTCARD") in Dinodirect http://www.dinodirect.com/li-ion-battery-fast-chargers-multifunctionl-cylindrical.html

Does anyone with this charger feel the battery in slot #1 is warmer than slot #2 and so on? Not that the heat is really noticeable just slightly warmer down the line. I am currently recharging Samsung ICR18650-22E recovered from an old laptop cell. So who knows the battery state, but I just think it's a little weird that the slot #1 battery is heated a bit and the slot #4 battery is cool as a cucumber. (All reading the same charged voltage btw)

Price went up to $17.99

Lost my manafont virginity and used your referral code :)

Ive been using my Trustfire TR003P4 Charger for the last few months. Unfortunately, the batteries come of the charger between 4.21 and 4.23 volts (measured one hour after charging).

Does anyone know which components I might be able to swap to lower the maximum charging voltage? I really like the design of the charger but dont want to shorten the life of my batteries.

Soshine and Xtar can do 1A , but even they tapper off and the chargers are really not that much faster ..

If the cell is depleted enough , its going to take a while ,

Using my TR001 , I charged up my brothers 18650's , and it took about 10 Hours [ he really drained them ]

4.25 is about the accepted , dont get you knickers in a knot , voltage .. [ when charging ]

It just depends on the charger behaviour ...

Is it taking good cells to 4.23v - How much do they sag after charging [ Give it at least an hour ]

If its taking bad cells to 4.23v and say they sag to 4.15 after an hours rest , then your probably shortening the life of the batteries ..

If you charge to 4.23v and they sag to 4.21v , well , its not the end of the world .

I find the cells that overcharge , are usually the good ones [ lower internal resistance ] , but thats my chargers ...

Battery behaviour is interesting to say the least ...

Ive found that with this charger and older cells, it never reaches a high enough voltage for the charge light to go from green to red... its always charging and never terminates. Is this dangerous? Probably not, but it might be if the battery developed an internal short from the sustained abuse. With cheap chinese batteries, Id never risk charging unattended. That goes for all lithium rechargeables. Also, cell life can nearly be doubled if batteries in good condition are only charged to 4.15V, which is the case for most laptop batteries (by far the primary use of 18650's worldwide).

Id really like to see this charger terminate between 4.15 and 4.18V. Hopefully someone will figure out how to mod it. Old, any ideas? As it is now, its just another cheap charger that got buried in my junk bin.

Which Charger ? TR001 , mine does that from time to time , I pick up the charger and spin the batteries in there cradles and the light turns red ?????????????????????

Dangerous ?????? Wow , just depends on how it does not stop charging .. If all its doing is trickle charging to maintain a certain voltage [ working against the resistance of the battery - and not winning ] , then Id say no ..

But if it continues to drive up the voltage = Possibly

I treat the TR001 with care , and always use it with supervision , if the charger is taking too long to go red [ finish ] I will pick it up and spin the batteries , some times pull out the MM to see what voltage the batteries are at , older batteries with more internal resistance , can take longer to finish off , and can linger around 4.18 to 4.2v for hours ....

If you want a charger that finishes stronger , Soshine ... But they cost $20+ and trickle charge [ dont terminate ]

The TR001 , I might actually re-test the TR001 , be interesting to see what its doing , mine must be close to 3 years old ...

Got the WF139 and the TR001 around the same time ...

I noticed that this charger mentions 12v in the power input specifications. I'm off-the-grid and prefer to use 12v to power my electrical appliances. Does it come with a 12 plug and/or does it have a transformer that turns the line voltage into 12v for the charger.

Are you sure it's not cell related?

I'd think it might be an issue if you were running them in a flashlight that used 2 or more batteries.

anyone know of what car adapter will fit? what about this one

I have a few PS , and I tried one out 3.2mm Plug seems to fit and work , put the calipers on it , 3.5mm might fit ... ?

[ Checked again ] Should fit ,

great thanks old..I looked for a 3.2mm on ebay and came up empty..hope the 3.5mm fits!

Price went down to $ 13.39

But in that ad they never call it a Trustfire TR0003P4. It is called a "Multifunctionl Cylindrical Li-ion Battery Smart Fast Chargers"
