Is there any good external portable battery or charger?
Ive got one of these http://www.amazon.co.uk/New-Trent-Dual-port-IMP50D-Blackberry/dp/B004AM1OK4/ref=pd_cp_ce_1
5000mah: does what it's meant to do, you can charge any electronic device with it (that you already charge from a USB port).
It comes with a nice coiled cable which has a USB connector on one end, and 2 adaptors: mini- and micro-usb.
So you can use it for charging the external battery itself, and for charging the HD from the external battery. You can also use your own USB cables if you want.
Amazon also have an 11,000mah model!
They're much cheaper on Amazon than with the manufacturers, though you may find them even cheaper o ebay or similar. This brand had a lot of positive reviews on Amazon, and it seemed discounted, so I bought it from there.
I use Zagg Sparq
Specs:
6,000 mAh Lithium Polymer
Has the power to charge most smart phones four times
4 yellow lights indicate power level, 25%-50%-75%-100%
Has the ability to charge multiple USB devices simultaneously
I paid GBP21.95 for the New Trent 5000mah pack I mentioned in post #2.
It is now being sold on Amazon at GBP29.99
still a good price though, if you compare it to an OEM battery
just got this one today:

Ordered a universal one with wall attachment and car attachment and when I connect the USB to microUSB cord the phone doesn't charge. Ordered another stand alone car charger and it, also, doesn't charge. If I attach the USB cord that came with the phone to the wall/car charger it charges fine. Both, specifically said for the "Nexus One". Is it an amp issue? Most microUSB charger in the mall cell phone kiosks won't charge it either. Is it a proprietary microUSB cord that I need or a matter of amps or something?
Why not buy from Monoprice.com?!
I ordered 8 USB cords (2/each of 4 different lengths), 2 Car Chargers, and 2 Wall chargers. All work perfectly fine, and I paid under $25. (Wife has a CLIQ, so we got plenty to work for both of us.)
So, I don't know what your issue is... Other than just not going to Monoprice

well I havent ordered from monoprice since customers got slammed with bogus charges... i guess i could give them another try though, but still... kinda weary
Why? I had over $1300 attempted to be spent at Newegg, and my CC company called me and stopped the charges. Got a new CC in the mail the following day. Some random amount at Apple as well. LOL. Fun times.
(Yes, it happened to me. I'm fairly confident it was from the same issue as others..) But, that doesn't stop me from using a company that makes good products, expecially when they just made such a big mistake. Odds are, it won't be happening again for a long while
Either way... Those are risks with online shopping. You just have to make sure that your method of purchase has fail-safes.
I have a CRAP load of mini USB chargers (all HTC stock) and didn't want to buy more. I bought a bunch of Motorola mini to micro adapters off Overstock.com for $2 a piece and couldn't be happier. I also bought the official Google cradle to avoid additional wear and tear on the microUSB port.

I bought a car/home charger from eBay when I had my Motorola Cliq, and my home charger would keep going on/off charging. I later found out that it was the voltage issue, where the charger was giving a maximum of 5 amps and the Motorola Cliq needed 5.1V or something like that.
But most chargers I've bought don't power the Nexus One. What specific voltage or amps should I look for it to have? The two I bought off of eBay specifically said they were for the Nexus One. Neither worked. Sellers are putting any micro SD chargers up for sale assuming they will change the phone. They will not. What technical spec will tell me if it really will charge it?
Could someone post a link to a USB charger that absolutely works? I just bought another one from Best Buy that doesn't charge the Nexus. Made by Rocketfish and is suppose to be universal.
Thats really wierd. Every charger i've tried works fine.
You're charger should be outputting 5V and anywhere from 300mA upwards. There is no max mA limit because the phone will only draw what it needs.
This might sound patronising, and I really dont mean it to, but when you say doesnt charge how do you know?
Do you mean from totally flat it won't turn the phone on and start charging it, or do you mean when the phone is on the battery indicator doesnt show a charging, and the LED doesnt go orange/green?
Or do you mean it never charges to full?
When I plug it in it's as if nothing happens. No light, no thunderbolt symbol on the battery, no screen wake-up, nothing. Nada. Now, the HTC wall charger and usb charger work fine. But if a MicroUSB charger calls itself "universal" it does not mean it will charge the Nexus. The HTC HD2 charger my wife has works fine on the Nexus though.
Hmm strange.
The charge process works like this:
- Charger plugged in causes voltage change on +ve USB line - potential charger detected.
- Phone draws minimal current (50 to 100mA) and tries to negotiate USB power
-- If that suceeds it tries to increase power to 500mA if the USB port supports it. If yes charging starts at 500mA, if not charging starts at 100mA
- If USB negotiation fails, it checks if D+/D- are bridged.
-- If D+/D- are bridged, the phone draws as much current as it can/needs
-- If D+/D- are not bridged, the phone draws a max of 500mA
There's nothing special about the chargers unless they have been wired in some special way for a specific phone. Thats why I'm very surprised these chargers dont work.
I know that if I chop a USB extention cable and cut out D+/D-, my nexus charges at 500mA. I've tried this myself for a totally different purpose. Thats no different to ground and power being wired to a 5v source.
Odd, I have three car USB adaptors and two AC USB adaptors.. All charged the phone, although only the AC charger shipped with the Nexus would do a fast charge, and none of my car chargers would. I found one that was rated 1Ah and soldered the two middle pins, now it works as a fast charger too.
The Motorola P513 car charger (OEM designed for a Droid) gives out 950mA, is super cheap (~$3+shipping), and works great for a fast charge with the Nexus One.

Thank you sir. I've been trying to find a car charger that guarantees a fast charge.
Just ordered one from Play.com for £3.99 w/ free shipping.
Maybe now I can use GPS for more than an hour...
I dunno.
My motorola charger for my old bluetooth (H780?) works fine, as well as the original google charger. I also have a car charger for my old bluetooth as well.
My suggestion, is to only buy name brand chargers?

This P513 has also been the best fast charger for me...
Now I have 3 batteries and I have to find a USB-based charger for these batteries. Checked ebay and found they're plugged, but I found the quality isn't good and it makes a lot of noise to the power line (it causes loud hissing on amplifier and kills powerline network), so this is not an option for me.
Since I have centralized USB charger (modified from 7 port powered USB hub), I am looking for USB based battery only charger, but so far I only found a cradle with some other accessories which I don't use.
http://cgi.ebay.com/USB-Cradle-Dock...110463?pt=PDA_Accessories&hash=item2eb51d953f
Any suggestions?
Ive seen many universal types on ebay for years but haven't tried them myself.
There are a few $5 clip on style, desktop style and $30 model that comes with a car charger, but for $25 difference I would rather charge via a USB car charger to power the $5 lol

USB & wall charger seems convenient

I don`t think you would be able to crank it long or hard enough to do any damage. My HTC hero and now my Desire S both require quite high power to charge properly so I would be surprised if it was possible to get any useful charge into a modern smartphone with a hand generator.
I have tried several of the (cheap)emergency chargers that run on AA alkaline or rechargeable batteries and none so far have been able to deliver more than a 20-30% charge before the voltage or current drops too low to continue.
The best solution I have tried for time away from the mains so far is a New Trent 5000mAH rechargeable battery pack from Amazon. They also do an 11000mAH version. These have 500mA and 1A USB outputs and claim to be able to charge an Ipad. My 5000mA one will do roughly 2 full charges plus a top up which is useful for a weekend away from mains power.
The price is however MUCH higher.

Im using Powermonkey classic v2

1A output.
Huge accessories packed with pouch.
But, my Desire S charges only to 78%

A Good Charger from Ebay
I have a charger that can fully charge the Desire S battery, costs about 10$ on ebay, so far the phone battery is still at 100% for a few hours with normal everyday usage, i find it good enough for me.
The charging rate is about 300mA and not 500 or 800 as published.
It would be wise to buy a micro usb female to micro usb male extender cable.

I thought I would like to share with others my findings about the USB cable issues and the charging issues also reviewing few products.
I know that it would probably be best with some real table lab equipment but I have tested it with a usb multimeter device : PortaPow USB Power Monitor / Multimeter / DC Ammeter
Showing me Amps and volts.
It is true what is said that the device can detect to a degree the charger
http://forum.xda-developers.com/showthread.php?p=53917336
So I used combo of software and hardware testing. I also tested with a S3 and S4 rooted (custom roms), and nexus 7 2013 (unique to this charger that it specs the 5v at 5.2! @ 1.35A and it does push more, to other devise as well)
Not all cables are equal; even not all OEM will work past 1A. It seems that most OEM’s cheat by using a shorter micro USB cable to get better charging results, this is the question many ask why so short cables, the OEM’s are only now slowly moving to thicker power wires IE 28/24 in there OEM usb cables.
Now my findings about the PortaPow USB Power monitor and any of the kind, is that it seems to effect the charging Amps of the device and also effect any smart chargers (will talk about below)
In the past I used to use exclusively the “Battery Monitor Widget” by 3c, lately I went and got also “Galaxy Charging Current Lite” for whatever reason my S3 shows as incompatible? Thought it should work on it, my S4 installed and shows max and reference/average
Test 1: S3 Genuine 100% OEM cable (I know because I bought the S3 new @ t-mobile)
Test 2: Claimed Genuine Samsung Micro USB cable 5 feet ECC1DU6BBE
Test 3: Nexus 7 2013 usb cable (is claimed to be a 28/24 AWG)
I was skeptical about the Claimed Genuine cable, and though it looks and feels just like the real thing, it varies in the logo and length. Performance wise has shown consistently of a 0.1-0.15A lower than the Genuine Samsung cable that I have from S3. This was done with the USB power monitor and with the Galaxy Charging Current Lite app, it even said 860mAh vs 760mAh when I tested the cables, but genuine cable did push up more power and the software was wrong as I have seen over 1.13A with USB Power monitor, but as said the real Genuine cable was better.
The Nexus 7 2013 micro USB cable that is short, performed the best, gave the max Amps out of all the cables. I will test my Monoprice 28/24 cables and update this thread.
Quick tests of chargers:
Car charger form Amazon,
PowerGen White Dual USB 4.2A (20W) Car charger Designed for Apple and Android Devices
I quickly tested to see if this thing will push past 1A and it did at the time I was testing with nexus 7 and its cable with the usb power meter, and It was pulling around 1.13A
Next up single wall charger, I saw this and had to buy!
Blackberry Folding Blade Charger for Playbook rated at 5v @ 1.8A! priced under $5!!!
I tested this one with the software on my S4, it quickly showed after few min pulling 1.4A and Galaxy charger showed maxed out 1900 on all!
I think this one wins for the cheapest and sturdy charger, just shy of 2A!, will become my work charger, the cable is nice and thick along with pretty good length 6ft+!
Next up I had to get me a family charger (4-5 port)
I get tired of short cables on wall chargers, so I went and got
Anker® 40W USB Desktop Charger
This charger claims a total of 40w for 5 ports! With intelligent device detection PowerIQ.
This charger so far (1 day use) has been great, I connected the S3 and the power meter showed 1A, I connected the S4 with the meter and was only getting 1.13-1.3A, the software did not show max, so here is the issue seems the usb monitor will cause the charger to not read the devices to there 100%, after taking it out and connecting it directly the galaxy charger showed maxed 1900mAh
The USB cable used was the nexus 7 one.
What I love about this charger, no lights! Perfect for me for overnight charging, also has standard power cord, the unit itself is quite compact too, now I can have short usb cables 1.5ft or 3ft ones and not worry about reach, as the charger can stay next to your devices, simply use conventional power cable extender on the charger unit, not on your usb devices!
I will conclude that it seems now since we are pushing past the usb spec for charging, that the shortest cable is best, be it 28 awg or 24 awg, and of course OEM’s already knew that, I am pretty sure that the OEMs are switching to 28/24 awg cables

if people are interested, I can designate some time and take few pics of the monoprice cables, and show why they fail, its obvious but need a good pic to show the reason, maybe we can find a way to fix them?
the cables are great, the connectors look great at first but are not so great
I just ordered the Anker 40W USB Desktop Charger on Amazon with same day shipping for $5.99. Thanks for your review!

that was even better bargain heh
the USB cable is as important as the plug. I use an ANKER 4-port plug with a factory S4 cable. It runs at 1900, same as if I used the factory S4 plug. I ran a whole experiment too. I had a USB cable IDENTICAL to my S$ cable, and it only charged at 320 with the same ANKER or S4 plugs. My S4 has a popup telling me to use a better charger
I just bought an 5 pack of "TronsmartPremium Micro USB Cable with Gold-Plated Connectors in Assorted Lengths (6ft, 1ft, 3.3ft x 3) for Android, Samsung, HTC, Nokia, Sony and More (Black)" for £5.99
And i am charging my Tab S1 T800 at 1720ma using the 6ft cable that is the same speed as my T800`s Samsung OEM cable, which is amazing as the longer the cable the slower the charge usually is.
Remember the quality of the charging cable is only half the story, the charger has to be able to deliver enough power and identify itself to the tablet as an high power charger, otherwise the tablet will only charge at a slow speed.
John.
If you have tested any charging cables with an usb power monitor/meter and get high charging rate add the brand below.
I used remax 6ft for a long time and still powerfull , it charge my tab s t805 very quickly 20% for 1 hour less ( sorry my bad english )
Yeah, It take about 5 hrs for a full charge on the 10.5"
EDIT: The "Tronsmart" cables i recommended in my first post seem to be out of stock on Amazon UK at the moment.

Old thread, but I personally just buy the "Amazon Basics" micro-usb cables. While I haven't benchmarked the charge speed of the black Amazon cables against the white Samsung cable, I never had any problems with the former. The Amazon cables are thicker and feel better quality than the original.
I can charge my 10.5" at full speed 1.7amp with a 6ft Tronsmart cable now that is nice, I bought two packs they are only £6 for a 5 pack

Eleta cables 3ft best. But use a Anker charger. The Anker charger is so much better than the oem one.
The Amazon basic microusb cables get a lot of bad reviews and they are not that cheap, The Tronsmart ones i bought are rated a 3amp and 99% of the reviews are good, and you get twice as many cables for the same price.

My experience was that I have about six of those cables all around the house and also in the cars. They work just fine.
