Hi All! So this is my first time starting a new thread so I hope I'm doing this right. I couldn't really find a thread specifically for battery banks or battery backups so I thought I'd start one.
I was wondering what is everyone's method of backing up/recharging your battery for your cellphones? For me, the battery that comes with my phone is enough to get me through the day usually and I just charge it every night while I sleep. If I go on trips, I use the Rav Power 10000 mah battery bank. I find this a bit bulky but it works great and lasts many charges before I have to recharge again.
Everyone's taste and preferences are different so I'm seeing what other options are out there that may be lighter in weight. I'm thinking of getting their smaller one, the 5200 mah, and have this in my backpack or car for just in case.
Any mini reviews of what you have would be great :good:
Wow, cool gadgets, I need to get a bank for just-in-case emergencies. Thanks Currently i use a solar powered charger, which is really slow and somethings doesn't work as desired. Looks similar to this http://www.amazon.com/External-Univ...=8-4&keywords=solar+powered+cellphone+charger
Ive bought one at sunsky from china battery about 4000mah, but it was year before, now there is a better.
I used to have a bank that looked like a GBA SP, with foldable screens. In the screens were two solar panels, which charged the battery of, I think, about 2000mAh or something like that. The thing is now broken though. Still looking for a nice (affordable) replacement
Mine is Anker 5600
I use the Belkin 4000, size similar to a ext HDD and look nice, pocketable too

Charger considerations
Hi,
I need advise for the following:
Charger A (Li-polymer battery) output : 5V, 1A
Charger B (Li-polymer battery) output : 5V, 500mA
Device input: 5V, 750mAH (Li-ion / Li-polymer)
When using Charger A, some people comment that it will limit the current of 750mAH for the device and the device's battery should be fine since both the charger and device are at 5V. However, some people comment that this will shorten the battery life of the device since it will perform a 'quick charge' using 1A.
When using Charger B, some people comment that the device will draw more current than it can deliver and causes it to heat up and reduces the charger's life. However, some people comment that Charger B will extend the battery life of the device since it performs a 'slow charge'.
I also read that USB pins on the charger denotes if the charger is a PC or a dedicated charger. If it is a PC, the device will limit the drawing current. If it is a dedicated charger, the device will draw more current to charge itself.
I am confused as to who is right and which charger should i be using.
Can someone enlighten me ?
Thank you very much.
bought this one from Ebay, has not yet arrived, therefore I cannot tell if its good or not.
but for its price its quite a good bet, 12000mAh for 33 bucks (on sale until tomorrow)

I recommend Anker 5600 is very good for that stuff.
Hi, I use choiix power fort 10Wh http://www.coolermaster-usa.com/product.php?product_id=3001 it have 2700mAh and it's small and looks very nice. It can give one full charge for my SGSIII
I went on a trip this year and searched for a good bank, and this showed up.
http://www.sayes.co/20-powerbank.html
I tried it and it was really good, it has lots of adapters and it's cheap =P
I was able to order a RavPower 5600mAh on sale a while back ago, that was posted on slickdeals. here. I am pretty happy with the performance of the little backup, it defiantly gets the job done. My only complaint is that the body gets scratched up easily.
I was comparing the Ravpower and the Anker 5600 and they both look exactly the same except that both are branded with their logos. So I'm wondering if they're from the same manufacturer. Going to have to do some more research. However my current Ravpower power bank I do have is working great and I love this thing for trips.
I'm also thinking of getting a solar one for my 3day emergency/bug out bag. Thanks for all the suggestions.

Yeah, can someone please let me know if they are the exact same manufactuers, except for the company logos on them? I am deciding between the two. Also, what do you guys think of their 2600maH stick version? Which manufactuer would you go for over the other and why? I am very interested.
I'm using a "Scosche SolBAT II Solar Powered Backup Battery and Charger" which I bought off Amazon for something ridiculous like $15 last year.
I bought it for hiking mostly as an emergency charger. I use a Huawei phone as a GPS out in the wilderness, and the GPS app (Androzic) is quite power intensive. I have also used the same device on an iPhone and an iPod touch. The Huawei phone will receive a full charge from this battery, but the iDevices will only go to around 75%.
The solar cell on the back of the battery isn't all that efficient and will take about two days to charge the internal battery, but having it there gives you more options should an emergency occur while in the wilderness. A half hour charging in full sunlight would provide enough power for a short call or a couple of texts to family or emergency services.
The device comes with suction cups and a small carabiner, so it can be stuck to the inside of your car window or clipped to the back of your rucksack. The device is lighter and smaller than the average smartphone and can be fully charged by USB in about three hours. Interestingly, the device has a LOT of bad reviews on Amazon, so maybe they simply sent me a good one.
I also have a very cheap and nasty handcrank USB charger from dealextreme which can be used to add a bit of juice to the solar battery pack at night or in cloudy weather or can directly charge the phone in an emergency. It's a little flimsy and takes a fair bit of cranking to get enough juice for even one call, but it weighs nothing, cost about $2 and is cheap insurance out in the boonies.
My list of power equipment for the phone/GPS and the iPod Touch for a multi-day walk are as follows:
Short Micro USB cable x 1
iPod USB cable x 1
Scosche SolBAT II battery/charger with alloy carabiner
DX hand crank battery charger
Total weight is less than 200 grams

That is a nice list of equipment. How is the solar powered charger coming along?

Honestly i went with pricing. I assume if they look the same they are from the same vendors/manufactures but different brand/company. Reviews for both sound very good too. Ravpower had a promo going on a while back and i tend to see them pop up from time to time on slick deals. The stick might give you one charge but since it looks smaller than the rest, it may be the easiest and lightest to carry around. I say get a decent sized one. Anywhere between 5600mah to 10000mah so you can go through a few charges without needing to charge again.
I have a 6600 mAh(well, in my experience it's not true, more like 4-4.5k), but I rarely use it after I bought a tablet with a fullsized usb port in it.
solar charger
I was looking for a solar charger. I bougth one but it crashed in two days. Therefore I returned it and now I am waiting for another one. In the place I live there are few options
This is the external battery that everybody should have! No need to have any cables or wall adapters with this one!! I’ll explain later.
When you open the box, you are first greeted with a “Thank you for your purchase!” card. Beneath that is the battery in a plastic wrap. The entire battery is in a plastic molding. Once you pick up the battery and plastic molding, you find a warranty card, an instruction manual, a micro-USB to mini-USB adapter, and a micro-USB to Samsung pin adapter. You also find a 2-ft long micro-USB cable and a neat carrying pouch. The carrying pouch is so great, you’ll love it as soon as you touch it.
First Impressions: It feels REALLY nice in your hands. It feels so premium and high-quality. The product has a really nice matte-finish with a brilliant black color. I fell in love with it immediately. It has a built-in wall charger to charge the unit, so no need to carry an extra wall adapter. Also, it has a built-in micro-USB cable, so you also don’t have to carry a cable with you. If you want to charge another device, there is a port at the bottom that is covered with a flap that you can easily access to charge your second device. You just plug in the wire and plug it into your phone and BAM: it’s charging. The built-in micro-USB cable charges at 2.1A and the port at the bottom outputs at 1A. The battery has a button in which you press to have four LED lights light up that tell you how much power the battery has left.
After using the battery for some time, I noticed that if you pick it up with oily hands, the battery will get oily stains. You can easily wipe them off, but it is just a little heads-up. I like how it is scratch-free; that is a huge plus. When you plug in your device with the cable that is built-in, it is a little awkward stacking your device on the battery at first because you’re afraid of breaking it. Eventually you get passed that, but it is a small complaint. After the cable is bent a certain way for a while, it forms to that shape. Luckily, when you put the cable back in the battery, it is formed back to its straight shape. In other words, the cable is malleable. I like how they’ve packed in 9000mAh in such a small form factor. I don’t like how big it is, but I can’t complain since it has a built-in wall charger AND micro-USB cable! This battery is pretty great!
Recently I’ve been loving this over my other batteries because I can just throw this in pocket and I’m good to go. No need to carry anything else to use the battery or to charge the battery. This would be great for students, people that work, just about anybody that owns a phone or tablet!
Overall, this battery is awesome! The fact that the wall charger and micro-USB cable is built into the battery is awesome. Along with the fact that it has an amazing build quality and form factor, it’s pretty awesome! I highly recommend this if you want a battery but don’t want to carry so many extra things around with it.
I was provided a unit for testing purposes and I promised to provide a completely honest and fair review.
Unfortunately, I cannot post the link to this product on Amazon because posting commercial links is forbidden, but you can find it on Amazon by searching for the product's name that is in the title of this thread. Thanks!
Overview
Quick summary - great little device really solid and well balanced with three output slots to charge two devices. The hugh 10,000mah it enough to keep several devices topped up for quite some time. Despite its capacity its not too heavy, mine weighed in at 246g / 8.7oz).
Unboxing
So in the box is the battery pack, a short black USB lead and the instructions. The battery pack has a really large capacity at 10k mah which is enough to charge a Galaxy S6 up a few times before itself requiring recharging. The battery pack is black plastic body with orange plastic trim on the top and bottom. There is three USB outputs all at the top of the unit.
Despite the capacity of the internal battery the weight of this doesnt feel too bad, weighing in at 246g which is really isnt that heavy and the slim profile means that it will slot into a jeans pocket no problem.
On the front are 4 little blue LEDs which light up to show the capacity. In theory each dot should be enough to deliver 2,500mah of juice so in theory each light of power should easily charge any modern smartphone, just for reference the capacity of my Galaxy S6 is 2550mah. On one side is a plastic button you can press to view the charge or turn the pack on when you want to start charging a device. Lumsing doesn't specify the rating of each, but the device's maximum power output is 16W. That means with three devices connected charging will be pretty slow, with just 5W available from each. Testing out each port with Ampre the average output for my Galaxy S6 was 1000ma, it charged my S6 fairly quickly (about 1 hour 30) from nearly empty so the device delivers a amount of power from each port when charging a single device.
Overall I really like this pack, its nice, solid and premium feeling, works well and having three output ports is always a plus and pretty handy with lots of devices being USB powered, thi feels like the main selling point for this device. I can see this being used by people away long long trips or away camping or hiking where there is no access to an outlet to keep your smart device topped up. I really like the slim design which means it can fit in a pocket nice and easily.
This is probblly the best battery pack I have seen so far
The battery pack is gold metal with plastic on the top and bottom, the feel of the device is really premium and solid feeling like it could take a good knock should you drop it. Despite the capacity of the internal battery the weight of this doesnt feel too bad, weighing in at 260g which is heavy but doesnt feel like much more than some of the smaller battery packs ive reviewed. The battery pack feels very well balanced and isnt heavy down one end or the other.
On the front are 4 LEDs which light up blue to show the capacity. In theory each dot should be enough to deliver 3,350mah of juice so in theory each light of power should easily charge any modern smartphone. On one side is a button you can press to view the charge or turn the pack on when you want to start charging a device. On the top is an LED for which lights when charging the pack, a micro USB input and importantly two USB output sockets, adding to this devices versatility - the ability to charge two devices at once. The max output in total across both ports is rated at 3A, the output from each port isnt listed and it isnt listed if one port supplies more power than the other. Testing out each port with Ampre the average output for my Galaxy S6 was 1200ma, it charged my S6 fairly quickly (about 1 hour 20) from nearly empty so the device delivers a good wack of power. The little micro usb lead supplied is a fair length, long enough not to have my phone right on top of the battery pack. Also a nice plus is that the supplied cable also works as a data cable, something that doesnt always happen with battery packs. Overall I really like this pack, its nice, solid and premium feeling, works well and having two output ports is always a plus. I can see this being used by people away long long trips or away camping or hiking where there is no access to an outlet to keep your smart device topped up. The weight and size means that this would fit nicely into a pocket or backpack no problemOverall I really like this pack, its nice, solid and premium feeling, works well and having two output ports is always a plus.

Also if you are interested in purchasing any lumsing power bank, please let me know and I can give you a coupon code for a discount on your purchase.
Does the powerbank also charge itself quickly?
Would love a coupon code!
As usual, this newest Inateck Charger feels like Quality. I received the unit about a week ago and have been putting it through its paces.
Firstly, the little things...
The packaging is minimal and effective. It looks nice and not cheap.
The USB-C to C plug that comes with the charger is absolutely solid. Clearly well made and not a thin afterthought. I love the fact that it has a hook and loop style cord wrap already attached to it instead of a plastic twist tie. It's little things like this, combined with reasonable prices that make Inateck a great company to buy from.
The power block has flip up prongs (US) that make it a great travel charger as well as a home unit.
It's not the full 87W that Apple's big charger is, but it's plenty fast and capable enough.
I have charged my Nexus 6P with this unit and it is indeed Power Deliver fast charging. My Chromebook and Macbook both charged rapidly as well.
This is a great unit for a reasonable price.
For just under $37 at Amazon, It's well worth it for the quality and speed alone.
