Guest waqasahmed Posted February 22, 2011 Report Posted February 22, 2011 Well, there is some talk about third party chargers and whether they will work. Whilst some with higher currents will work, it is not too good for the phone. For this reason, you could possibly get a genuine ZTE Blade charger from the ADVERTISING SPAM shop on eBay for £4.49 with free delivery(5V 700ma) or you could get a cheaper charger which is undervolted (Vivaz U5) ever so slightly and has the exact amount of current running through it as the original ZTE chargers from Amazon Another charger that is safe to use would be the 6500 classic charger where it has 5V running through it and 550ma ie: within the safe limit. This type of charger is set at the correct voltage and outputs slightly more current than the Micro USB cable when connected to a PC
Guest targetbsp Posted February 22, 2011 Report Posted February 22, 2011 (edited) You only need the voltage to match. The current a charger can provide is the chargers maximum - it doesn't force that upon what is being charged. The same or higher is perfectly safe - the device being charged will only draw the current it needs. It's lower amps that will generally cause a problem - though as these things charge off usb ports I guess they are fairly flexible in that regard! Edited February 22, 2011 by targetbsp
Guest digisol Posted February 23, 2011 Report Posted February 23, 2011 Agreed. I have a 5V source pumping out at 1A - think it might even charge faster than the ZTE charger which came with the San Fran. Shows up as AC charging too - not bad for a mobile backup...

So you're saying that a 5V charger with 1A of current is safe? Isn't it not recommended to charge at the absolute max it can handle? hence the reason why the stock ZTE charger is rated at 5V and 700ma? I do have a charger here that is rated at 5V and 1A
Guest targetbsp Posted February 23, 2011 Report Posted February 23, 2011 For powering a device you need a charger at the correct voltage that can provide a current equal to or higher than what the device requires. This is why universal chargers only need to allow you to select the voltage and not the current.

Isn't it not recommended to charge at the absolute max it can handle? hence the reason why the stock ZTE charger is rated at 5V and 700ma? I do have a charger here that is rated at 5V and 1A As long as the voltage is correct (and I think for the Blade/San Fran that figure is 5V) then you could have a 5V charger rated at 1,000A if you wanted and it would be safe because the battery in the phone will only draw what current it needs, ie, 500mA, 700mA or whatever. Just because the charger could provide 1,000A does NOT mean that the battery will draw 1,000A. Some interesting info at http://batteryuniversity.com/learn/article...m_ion_batteries

Would it simply not charge?
Guest cacoe Posted February 23, 2011 Report Posted February 23, 2011 http://www.amazon.co.uk/BlackBerry-Travel-...mp;sr=1-1-fkmr0 Exact same charger from amazon which is also sold by ADVERTISING SPAM I got my blade from ADVERTISING SPAM and I think they're fairly reputable but I prefer buying stuff through amazon over ebay. Just thought other might feel the same.

Just thought other might feel the same. Your choice, I suppose. I would prefer to buy the same charger on eBay if it costs the same, as it means that my feedback is slightly higher and I receive some money back via quidco. Annoying that PPM don't have this charger on their site, as they give cashback through their own site as well
Guest shootomanUK Posted February 24, 2011 Report Posted February 24, 2011 (edited) Hi guys, i have just stumbled upon your post and i can confirm an alternative replacement charger for the ZTE BLADE. The charger is for the VODAFONE 340 MOBILE PHONE it has the micro usb plug and is 5v 700ma and is made by FOXLINK i know this because i have been using one by accident thinking it was the charger i got with my blade, but it was my girlfriends that was plugged in the wall lol hope this helps oh and by the way im not sure about the blackberry charger as i have had a blackberry 8110 in the past and it is a different plug (mini usb) cheers ! Edited February 24, 2011 by shootomanUK
Guest daveypro Posted February 24, 2011 Report Posted February 24, 2011 I use my blackberry one without problems, must admit i havent checked the voltage or nowt :huh: http://www.amazon.co.uk/Genuine-Blackberry.../ref=pd_cp_ce_2
Guest ronc2000 Posted February 24, 2011 Report Posted February 24, 2011 This phone is not fussy. Any USB source is OK. There are probably plenty in your home left from old devices already.
Guest mug2k Posted February 24, 2011 Report Posted February 24, 2011 I'm using my kindle charger and it seems to be faster than via the PC.
Guest curl66 Posted February 24, 2011 Report Posted February 24, 2011 (edited) i am using a nokia charger rev B. with 1200ma. works fine if touchscreen doesnt respond while charging voltage is out of range (too high) nokia charger rev c doesnt work Edited February 24, 2011 by curl66
Guest surfatwork Posted February 25, 2011 Report Posted February 25, 2011 I am using a Nokia N86 charger (5V, 1200mA) and it works just fine. @targetbsp is right - the device will only draw the current it needs.
Guest wiffeltje Posted February 25, 2011 Report Posted February 25, 2011 (edited) I'm using my kindle charger and it seems to be faster than via the PC. That is correct. A 'correct' charger does short the two data-lines of the USB connector. This is the sign for the phone that it is connected to a charger and can draw more amp's. In this case, my phone draws up to 700mA. Without the shorted data-lines, the phone has to assume it is connect to something like a computer and should (by the USB specifications) not draw more then 400mA. The ZTE Blade does this correctly. In this case, my phone draws up to 360mA. So, it will charge about twice as fast if it is connected to a 'real' charger. Edited February 25, 2011 by wiffeltje
Guest agreenjesus Posted February 26, 2011 Report Posted February 26, 2011 USB3 can supply more current as well as full duplex, I wonder if this is supported by the blade?

Guest wbaw Posted February 26, 2011 Report Posted February 26, 2011 USB3 can supply more current as well as full duplex, I wonder if this is supported by the blade? No, the blade doesn't have usb3, it'd cost more. As other posters have said any usb charger over 700mA will be fine, less than 700mA & it'll charge slower.
Guest Grain Posted February 26, 2011 Report Posted February 26, 2011 As other posters have said any usb charger over 700mA will be fine, less than 700mA & it'll charge slower. If the charger is wired so the Blade recognizes is as an AC charger (not PC USB connection), the Blade will (try to) draw 700mA. If the charger is not rated for 700mA or more, the charger will get very got, shutdown, or drop voltage. The Blade does not charge if the voltage drops much below 5 Volts. However, normal USB chargers do not have the data lines shorted. The Blade will assume a standard USB connection then and charge more slowly - guessing from the charging time it seems to draw about 350mA then. See the wiki article linked to below for details.

The ZTE Blade correctly limits the current it draws. I did try this with my lab power source. I can easily source a lot of current to the phone without harming it. It will NOT take more current than it is supposed to do.
Guest toggle Posted February 27, 2011 Report Posted February 27, 2011 I have bought a nokia charger 1200 ma. it charges but touchscreen does bot respond during charging.

Well this is untrue, according to both my own knowledge, common sense AND the wiki page you linked to. If the charger is rated below 700mA, the phone will simply charge slower, it will not "get very got" by which I assume you mean hot, and will NOT drop voltage. Therefore the blade will charge normally, and there is no threat of it not charging from chargers rated less than this.
