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)
not able to post links, just type w ww. before the following

Zagg sparq 2.0 highly recommended

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
Hey guys just here to write a review on the Lepow 6000mAh Stone Power Bank. If you'd like to see the unboxing or if reading is hard you may find my video version here: https://www.youtube.com/watch?v=rvN0mfV4HDA&feature=youtu.be
I'll start with the packaging. It's nice looking and simple, with an emphasis on renewable materials. It's kind of nice that they took the effort to do this, as for the price I would have imagined more of a plain cardboard box or worse, that awful plastic packaging. So there's a plus for the packaging. They even threw in a bunch of goodies, which the note inside said was because it was purchased from Amazon. Such goodies included an extra carrying bag, stickers, cord wraps, a suction pad to stick the Power bank to smooth surfaces (yes, I tried, I can stick my Nexus 5 to glossy surfaces if I wanted to =P), a stylus for capacitive screens, a screen cleaner, and a micro SD to USB adapter. It was kind of a nice extra.
On to looks and build quality. I don't get the sense of cheap here..in fact quite the opposite. It's definitely solid, which combined with the shape makes it feel good in the hands. It doesn't creak when stressed, and it certainly doesn't feel like it's gonna fall apart any time soon. It's nice too look at as well. If you're into the clean modern look than you'll probably like it as well. It also comes with a flat style USB to Micro USB cable, and a fabric carrying pouch.
Without further adieu let's talk about the good stuff, performance. First off, there's two ports, one standard charge and one quick charge, which charge at 1.2 Amps or 2.1 Amps respectively. I don't own a tablet or anything, so I don't have much use for the 2.1 Amp port, but it's nice to know it's there if I need it. Both ports I tried were pretty much like charging my phone plugged into the wall. There's a handy charge remaining button which lights up 4 lights, depending on remaining charge. This is probably standard but it's still a handy thing to have. As we all probably know, the Nexus 5 has a 2300mAh battery. Being a 6000mAh power bank it performs exactly as expected. Discharging to 20% or less and charging to full with the phone on, and unplugged as soon as I noticed it finished, I was able to get about 2 and a half charges. I was left with about 68% on the remaining half charge.
So, would I recommend it? Well, considering it's 20 bucks on Amazon at the time of this writing, I'd definitely say so. Considering for that price you get a good quality power supply, with a bunch of little goodies, all of which packed in renewable materials, so you can even feel good about it. I'm happy with it anyways.
Thanks for reading!
I picked up this thin 10,000 mAh power bank last week at a kiosk in the Cherry Creek mall near my house. I was in the market for a small and powerful powerbank to keep my phone and tablet charged throughout the day and found this is a great solution. Here are my thoughts:
The Jumpr Slate comes extremely well packaged in this orange box. On the front is the usual branding it states that it is a 10,000 mAh powerbank with 2x 2.4A outputs. The packaging looks and feels solid.
On the back of the box are more details on what sets this powerbank apart from the pack like an industry leading 93% power transfer ratio, its light and sleek design at 6.7mm thick and only .77 lbs, and a badge showing that it meets worldwide safety standards (UN 38.3). There is also a list of devices that can be charged with the Jumpr Slate 10K.
The overall design of the Jumpr Slate is very nice. It is only about a half inch thick and the pattern on the top is simple yet provides a clean and industrial look, as well as providing a nice texture to grip onto.
The binder holes on the side make it easy to conveniently clip the Jumpr into a a notebook, and the thin design means it takes up very little space in a tablet case or briefcase. There is the EnerPlex branding in the corner but it is not over branded or too in your face.
On bottom panel there is a mini USB input to charge the Jumpr, and two 2.4A USB outputs. There is also a small button for turning the Jumpr on/off, and 4 LED indicator lights that display the amount of charge that the Jumpr has left.
To test out the Jumpr Slate 10K I let the battery in my Galaxy S4 run all the way down and I then used the Jumpr to recharge it. It took about the same amount of time as charging from a wall outlet, same with when I plugged in my GoPro. After charging both devices the indicator showed 50% battery life left on the Jumpr.... not bad.
PROS:
Charges devices as fast as outlet
Extremely thin and light
2 USB Outputs
CONS:
Will not charge laptop
Recharge time of about 10 hrs
Overall I love this thing and it has a permanent home in my computer bag. I also bring it with me to provide a backup charge to my GoPro when adventuring in the Colorado Rockies.
Overview
Quick summary - great little device with a handy LED torch, really solid and well balanced with two output slots to charge two devices. The hugh 10,000mah(37Wh) it enough to keep several devices topped up for quite some time. Despite its capacity its not too heavy (226g / 8oz).
Unboxing
So in the box is the battery pack, a very 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 two USB outputs with a combined max of 2A.
Despite the capacity of the internal battery the weight of this doesnt feel too bad, weighing in at 226g 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 white 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. The button feels a little flimsy and isnt always easy to press but its not something that will be used loads. If you double tap this button it will turn on or off the LED torch function, however it feels like this wait time has been set just a bit too long. On the top is an LED for use as a torch and 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 2A, 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 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.
The little micro usb lead supplied is pretty short, and it would have been nice to have a bit more length to this however that being said I have loads of long USB leads and not any which are really short so this may actually be a blessing in disguise.
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. I really like the slim design which means it can fit in a pocket nice and easily.
For people who arent sure about details on powerbanks or what they are all about EasyAcc has quite a good article located here:

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.

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.
