[Q] External Battery

http://tinyurl.com/2wmzn39
I would like to find out how long would this pack last with eneloop battery's.
anyone have any idea?
also if it would be possible to build or find a external battery that can take 8AA battery's.

Eneloop AAs are rated 2,000 mAh?
my rough guesstimate, you'll get about 4x your normal stock battery life from the pack, after you factor in losses from heat and from converting the pack's juice into your cell battery.
maybe a little more?

whats the total mah for the pack if i put in 2000mah batteries? 10 000mAh?

RAVPower rp-pb03 external battery
I own one before, it is really charge my HTC EVO 4G with bad result. I only use the device once before it basically melted. For reference, I used Sanyo Eneloop batteries in the charger and I used the retractable cable provided with the mini usb adapter. The charger did recharge my batteries, but it got so hot when charging my phone that the outer case warped from overheating. So I ask to replacement, however, the second one I received got the same problem. Also the charging speed is very slow.
I bought another RAVPower rp-pb03 external battery on Amazon one month ago. Since now the battery works very great. I love this device! Not only does it have a very handy flashlight, but it never leaves you guessing how much power is left. It works with my phone, my wife's phone and both of our tablets (all different brands!) The size is nice and compact, and I like the robust weight. It's easy to use, and compatible with everything I've tried! This is by far the BEST accessory I've bought for my electronics by far!

External USB batteries

Has anyone tried any of the external battery solutions available out there? I've read that the Kensington one is good, but it's only like 1200-1400 mAh !
I've run across a few on Ebay that are running 4000-5000 mAh - great for multiple charges!
Anyone have any feedback on any of these?

I have used a few different ones over time. I currently have an Energizer pack with a 4000mAh capacity.
I recently saw a a 40,000mAh pack at Radio Shack for around $120. I almost bought it, just on general principles.
Anyway, yes, the portable packs do work well. But remember that the mAh capacity of the pack doesn't translate 1:1 to charging capacity. The battery in the pack is only a single 3.7v LiPo cell, and the battery in your phone is ALSO a single 3.7v LiPo cell. These packs use a switching regulator to boost the output voltage, which means that the cell will be discharged faster than you might think. If you want to fully charge the battery in the Triumph, you should try to find something with at least 2000mAh capacity.
One of the more interesting solutions I've seen at the Sprint store was an integrated charger. It had a USB jack, a short micro-USB cable, and an AC adapter all built-in. So you could basically use the thing as a USB wall charger, then unplug it and take it with you when you expect to need a little extra juice on the road.
Personally, I'd like to see more portable Lithium-based packs that can also put out 12v for larger devices. Ideally, I'd love to be able to power my phone and a portable speaker system all from a single battery pack. Perhaps someone will get smart and build a box to house and adapt the 2-cell rechargeable packs used by RC car enthusiasts...

I purchased a 1500mah Anker battery off Amazon for $15. Works great!! Much better than 1380mah stock battery

Solar Charger

How do I make the http://www.harborfreight.com/1-watt-solar-power-pack-68691.html Charger my hp touchpad and iPad by the sun?
Is there an app that I need to install. Homebrew or app catalog?

Read the reviews and don't waste your money on it. Reviewers say it can take 3 days to charge up the internal battery and there's no data on how big that battery is though some say 2700mAh then you use that to charge your device, that might give you a decent charge on your TP but one charge every three days is not much use. If you want a decent battery based charger try something like the Anker 3 10,000mAh lithium rechargeable battery pack which should cost about the same.

Well for the first, people get extra batteries so that when the first one dies(OEM Samsung battery that came with the phone) they can just pop in the new one by anker etc. And keep on chugging without charging. Hope that helps. Also, after so many charges the OEM battery loses some of its MaH amps so people will purchase a cheaper(anker tends to be about 10-20 bucks less) to replace it. Price is always a deciding factor to most consumers, especially phone owners.

I get extras because I hate charging my phone. When one dies I pop in a fresh one and go. I am getting two ankers Monday so ill have three batteries.

From Note 2 experience, Anker OEM replacement battery performed and lasted longer than Samsung battery. Period! Plus, as some others pointed out, you can use external charger to juice it up, and just swap batteries on the go.
For external battery banks, Anker is also the way to go. Go to my Review Link in the signature where I have reviewed and posted detailed write up for close to a dozen of power banks. 6000 mAh is a thing from the past. Right now new power banks have 10,000 to 15,000 mAh of capacity in the same footprint as old one. Plus keep in mind, the actual capacity of external charger will be 30% due to usb port conversion (going from internal cell of power bank 3.8V to 5V usb port, and back to 3.8V on your phone through usb port - close to 30% loss due to efficiency).

Yes that 6000 mah power bank will give you only 1 full charge, and the charging speed is equivalent to USB. If you are doing NAV or some other heavy power draw, the external battery may not keep up.
And if I have to carry a spare, the internal battery is smaller and I know exactly what I am going to get in terms of performance

im finding that the anker 2600 batteries i bought are better than my two samsung batteries. i have two samsung batteries because 1 came with my phone and 1 came with the brand new insurance replacement after i smashed that phone. pretty happy with anker. no need to add bulk to the phone with an extended. just keep a spare battery when needed. i have 1 in my camera bag, 1 in my backpack i take to work, and 1 i can slide into my wallet if it's just me and the phone.

I bought Anker 2600 dual battery and external charger pack. Love it. Been using it and swapping batteries out every morning instead of being tied to a charger. Good for trips where I make heavy use of Cell phone to watch videos and such.
Had one issue. the internal connector that the pins that connect to the battery kinda broke on mine. The piece the pins are attached to fell inside the charger case. No problem though just opened it up and hot glued it back in place. All that keeps it there from the factory is glue and mine just came undone. Happened while traveling with charger in a bag with a battery in it, possible something pushed it hard.

Good to know that 2600 anker is better than actual battery... I was planning to get the 3k zero lemon but every one suggests is not doing much difference

Which Powerbank for Note 4

Hi guys
I wanted to ask which powerbank capacity do you recommend for the note 4 for at least one full charge ? I bought one from deboch 6000mha but I will send it back because its too big.

I've just ordered an Anker Astro 5200mAh:
https://www.anker.com/products/A1211012
https://www.youtube.com/watch?v=frhehPIqFKE
It seems that you actually get at most about 75% of the stated capacity from a powerbank (see this video: https://www.youtube.com/watch?v=zz4arPh-ch8). Even if you only get 66% of usable capacity from a 5200mAh Powerbank (as the video suggests), that should give approximately 3400mAh which is enough to charge a Note 4 from 0% to 100% (battery capacity of a Note 4 is 3220mAh).
The Astro 5200 is very pocketable at 5 x 3.4 x 1.7 inches, comes with a net travel pouch, and a USB cable, but I bought one of these tiny USB cables to use with it: http://www.ebay.co.uk/itm/131876034528

You need a powerbank that holds a larger charge than the battery of your device in order for it to get a complete charge. I'd suggest getting a power bank with at least 3500mAH capacity.

Much more pocketable and guaranteed one full charge is a spare battery! Only downsides are you can't be a good Samaritan and share and you can't use it on your next gadget

Yea, I have a spare battery too, and an external charger - I like to keep my options open, but it can be a bit of a nuisance removing my UAG case so sometimes a charger is handier.

terratec powerbank p4. used it at my holiday trip and holds the phone at full power more than whole day long using pokemon go ;D.

RAVPower's 20100mah has been great for me, and includes Qualcomm Quick Charge and USB Type C support: https://www.amazon.com/Qualcomm-Cer...qid=1471276085&sr=8-2&keywords=ravpower+20000

xiaomi 20.000 mAh will be the best : )

OP is looking for something SMALLER than a 6000mah Deboch, so suggestions for units over that size won't do. I've received my 5200mah Anker Astro E1 (mentioned above) and can confirm that it fully charges my Note 4 with a little to spare. It has a 2A output so charges quite quickly. Very pocketable and highly recommended, probably the best size/capacity ratio for carrying in your pocket:
https://www.amazon.co.uk/Anker-5200mAh-Portable-External-Technology/dp/B00P8SY7HQ/

Having used a few Anker, revspec and kasmish. I know i spelled most of those wrong. But they are all in the 10k mah range.
All of them will easily charge your battery 2-3 times. However some claim 2A but just isn't as fast. I much spend a little more money on a Quick charge 2.0 certified one. Quick charge 3.0 is out for a handful of new phones but the note 4 doesn't support it and most are lik the $50+ range.
Get a QC2.0 small 10k and your covered til the end of the phone life. They will run you $15-30. They are roughly double the size of your note 4 in thickness and thats it. If you can pocket your note 4, you can pocket the battery. But i normally pocket the battery pack and hold the phone. I keep it in the bag tho.
This to me is the best and future proof method. A spare battery is the fastest to go from 0-100 but w/o a spare battery charger, it could be annoying as well as it only works on the note4.

Xiaomi 20 000 mah. It has fast charge

If that's just for your phone, get a spare battery or two. Preferably with an external charger.
If you got your Note4 when it came out and use it regularly, your battery is probably significantly degraded by now or is starting to do so. So buy that new battery.
If you intend to do so, stay away from those cheap "Samsung" batteries on Amazon or eBay. These are all likely to be fakes or rejects. Either buy real (expensive) ones in retail packaging or reputable third party brands.

Anker powercore+ 10050 has qualcomm quick charge and is the perfect size. Amazon has it in a package with the anker wall charger that charges extremely fast. I now have Anker chargers for everything electronic in my life. Anker for life
