I guess: If you do a quick charge, the bigger contacts areas may be a little advantage or if the producer wants a high quality power connection even if the product is 10 years old.
Yes. Checking the temperature gives more security, especially for high speed charging and charging to 100%. If you charge slowly and up to e.g. 80% two pins are enough.
Hi!
Just wanted to let everyone know, this external universal Lithium-ion battery charger is capable of fitting the relative wide (~6cm) FP5 battery. I was also able to adjust the contacts correctly, and it correctly detected that my battery was near full when plugged in.
I havenāt tried to charge a battery with it yet (but Iād assume that it works, there isnāt that much magic involved in slow charging a battery (no magic 1h charges here, but thatās not the idea, going from 0% ā near 100% in 20 seconds is the idea, without trying to pushd 500kA at once into the battery without a fire and explosion hazard), as I have not picked up yet my 2nd battery from the local store.
Thanks for the heads-up 
Feel free to let us know when you have gotten to test it (e.g. charging time, maximum charge the battery reaches etc.), Iād be happy to link to your experience here then: External universal chargers for Fairphone batteries
Not to spoil any relief or anticipation, but reviewers note that the charger doesnāt have the CE conformity sign, which would make it illegal to sell in the EU, where the majority of Fairphone owners reside right now (not that Amazon as just a platform provider in this case would care, responsibility would lie with the seller āTrade Shopā).
The current product images at Amazon seem to confirm this.
Furthermore the electrical security of the US plug ā EU plug adapter solution included with the charger is described as questionable because it doesnāt really stick to the US plug and thus could lead to hazardous situations because the contacts could be exposed to touch or short-inducing materials while connected to power.
As you have the device ā¦ Can you confirm the missing CE sign and the plug adapter not sticking to the charger when in use?
I can sadly also confirm that I was unable to charge my second fairphone5 battery, no matter how I positioned the pins at all.
No CE mark.
The US-EU plug adapter is very questionable: Itās okay on the US side, if a bit loose, but itās a bit bad fitting on the EU side, and if you manage to get into a socket, unplugging it is a lengthy game of patience.
Well, I complained to Amazon that the product is faulty by design, letās see, but I also donāt expect them to react. Sigh.
Thanks for confirming. Well, since itās Amazonās delivery, at least returning it should be easy enough.
Iām a bit amazed the vendor as well as the seller blatantly in open daylight didnāt even bother to print a CE sign on the thing for the heck of it, as is done with many other potentially hazardous devices out there which arenāt helped in any way by just having it put on. Perhaps thereās a difference in penalty if charged with any of those deeds.
I tried this same exact universal charger in the pictures (bought on amazon) and it doesnāt appear to work. The problem is that the pins on the charger cannot make contact with the metal on the battery. This is because the terminals on the battery has these plastic dividers which are spaced very close together. The pins on the charger are a bit too thick to fit. Either that or the plastic dividers are too deep for the pin to make contact. Itās a bit difficult to see whatās going on exactly but itās clear that the pins are not making contact with the terminal on the battery.
When itās plugged in and not making contact it shows as 100% charged. Not sure why it does this. But with the battery there or with the battery removed, when the charger is plugged in the default screen is 100% charged
Apparently, they removed it from the store altogether, so I think your report had an impact.
Bummer though, Iāll be waiting for a working external charger too.
It would be nice if FP made an official one. It would be awesome if it could work as a power bank too, like the LG G5 one did.
Actually, Samsung, in days gone, sold replacement batteries in a small nice piece of plastic cover with an external USB connector, which doubled as a charging cradle.
So you had a nice cover to carry around your second/third battery in your pocket. You effectively could charge it away from home when visiting by connecting it to a basic USB charger. No dirt could get into the contacts or cause a short by mistake.

Hi all!
Did anyone have the chance to buy/test any other external charger? I already got my second battery and I would not want to waste itā¦ 
I tried the one here External universal chargers for Fairphone batteries - #39 by micha562 and it seems to work okay. The adafruit one at the very end
