These aren't your pocket-friendly power banks, but they can be your lifeline when battery life runs short across multiple devices.
Given today's power-hungry phones and tablets, any power pack under 20,000mAh shouldn't be considered high-capacity. While the majority of these beefier backup batteries aren't suited for storing in your pocket, they're still compact enough to toss in a backpack, suitcase, or laptop bag for a quick charge when you need it. Check out these five power banks that provide enough battery to keep up with the most demanding tech-lover.
Note: When we state how many charges you can expect to get from each battery pack, we're using a hypothetical 2500mAh phone as our basis.
CHOETECH 20,000mAh Power Bank
Rocking dual-USB outputs — one dedicated to Quick Charge 2.0 speeds — this power bank from CHOETECH has a 20,000mAh capacity. What's more, it can charge off of either a Micro-USB cable or an Apple Lightning cable, giving flexibility to anyone dealing with multiple devices. Keeping you on top of how much charge is left are four LED lights on top next to the main power button.
The first USB output provides a steady 1-amp charge and even devices that don't have Quick Charge 2.0 technology can still utilize the second blue-coated output thanks its safe auto-detection feature. When topped off, you should get 6 to 7 charges off this power bank.
Anker PowerCore 20100
Okay, so maybe this power bank can fit in your pocket — it's also one of the most compact power banks available for its hefty 20,000mAh capacity. Anker's PowerCore 20100 delivers 2.4 amps to both of its ports for a total output of 4.8 amps. It has four blue charging LEDs on the front for easy checks on how much battery life remains in the PowerCore; and when you do need to recharge you can do it with the included Micro-USB cable. Anker also features their Power IQ and VoltageBoost technologies to provide the fastest and safest charge to each connected device. Expect approximately 6 to 7 charges when the PowerCore is at full capacity.
EasyAcc Monster 26,000mAh Power Bank
If you're after more than just a pair outputs to keep your phones and tablets charged up, the EasyAcc Monster packs a 26,000mAh capacity and provides four USB ports as well as two Micro-USB inputs on the side that can work in tandem decrease recharge time up to 50%. With a total output of 4.8 amps, the more devices connected means a slower charge, but the overall convenience, functionality, and capacity outweigh reduced charging times.
Next to the USB outputs is a built-in LED flashlight that's handy for seeing in the dark, and on top are four tiny lights that indicate how much battery life remains in the power bank. EasyAcc has added plenty of safety features to prevent any damage to your connected devices, too. Capable of providing 9 to 10 charges, the EasyAcc Monster makes a great external battery to have on hand.
Anker Astro E7
The Astro E7 features a huge 26,800mAh capacity with a maximum output of 4 amps to charge up to three devices simultaneously. A single 2-amp (max) Micro-USB input charges the premium LG battery cells inside when connected to a proper power source. A small LED flashlight is located on the front, adding easy visibility in the dark, while 4 charging LEDs can be found on top of the power bank. As with most Anker power banks, their PowerIQ technology pushes the fastest and safest possible speed to each connected device. Fully charged, you can expect approximately 10 charges off the Astro E7.
Intocircuit 32,000mAh Power Monster
This beastly backup battery rocks an impressive 32,000mAh capacity that's able to provide power to phones, tablets, and even laptops. It has two USB ports on the front — one 2.1-amp and one 1-amp — next to a DC output for connecting any one of the included laptop cables. On top of its brushed aluminum chassis is an LCD display that provides readings of its power level and charging status. With over 13 notebook connectors and AC adapters for the U.S., UK, and EU, the Intocircuit Power Monster is the ideal power bank for serious traveling techies. Expect around 12 charges when it's topped off.

5 high-capacity power banks that are great for the traveling techie
Correct me if this is no longer true but it was as of last May... you can't carry a power bank that is larger than 20,000mAh on an international flight; probably true for domestic too. I had my bag diligently searched in China for lithium batteries and the label on the battery was specifically examined.
Less than 20,000mAh -> no restrictions.
Between 20,000mAh and 32,000mAh -> max 2.
Over 32,000 -> not permitted.

"Size limits: Lithium metal (non-rechargeable) batteries are limited to 2 grams of lithium per battery. Lithium ion (rechargeable) batteries are limited to a rating of 100 watt hours (Wh) per battery. These limits allow for nearly all types of lithium batteries used by the average person in their electronic devices. With airline approval, passengers may also carry up to two spare larger lithium ion batteries (101-160 watt hours). This size covers the larger after-market extended-life laptop computer batteries and some larger batteries used in professional audio/visual equipment."
So yeah - 20,000mAh.
160Wh = 160 VAh
160 VAh / 5V = 32Ah
32Ah * 1000 = 32,000mAh
So yeah - 32,000mAh ;-)
I hope airport personnel knows about this because I'm carrying an Anker PowerCore 20100 with me on my RTW trip. So far the only weirdness hit me in Asia - apparently, in Thailand it's illegal to check rechargeable batteries regardless of capacity. You must take them into your hand luggage, they actually scanned my backpack and ordered me to take the Anker out and onto my daypack to take onboard.
I have a RAVPOWER RP-PB043, 20Ah, with one USB type C, one quick charge and one 2A port output and quick charge input capable, it's awesome... I don't see any quick charge capable in that list

That looks like the one

My only issue with Anker chargers is they use a slick back plastic. It very slippery and scratches very easily. I wish they used something more durable.

How does a scratch affect performance?
Posted via the Android Central App
A deep scratch will deflect and concentrate nutrinos, reducing the ability of the polymer substrate to retain ions in the affected area.
Just kidding ;)

lol nice
Because it would look like ****. Like my old school ipod back that would scratch from air touching it.
I'd have thought That at least one power bank on the list would include a USB Type C port. There's even one on the list with a Lightning port.
Any opinions on the one plus power back??

Anything One Plus does, sucks so there you go
Wow; an article I can really sink my teeth into Thanks Brent!
I have nine power banks ranging from a 500 mAh keychain unit, up to a 15,000 mAh unit that you can knock someone's head off with, and all of them have been across the workbench for through testing (well, the Kmashi 11,200 is in it's second round of testing, and should be done in a few days). I thought I was set for a while, but some of these monster units have rekindled my interest in getting more to play with.
Just a quick note: Power banks don't deplete their cell(s) completely in normal use, so although you may have a 10,000 mAh power bank, it's not going to actually give you 10,000 mAh of output. Then there is a slight loss due to the charging process not being 100% efficient, so in reality, you can expect to have 55 to 70% of the rated capacity available. The very best unit I've tested (PowerAdd 2GS) delivered 69.94% of it's capacity, and the worst one delivered only 55.25% of it's advertised capacity. Because of these complications, the most accurate way to estimate how many times your phone can be charged is to subtract 35% from the power bank capacity, and divide that by the phone battery capacity. This will give you a good ballpark figure.
There's also lots of nuances to the testing that include logging if a bank will start charging automatically when connected (some don't), if they reliably charge to 100% (most do), and if they disconnect from your device when they can no longer actually charge (a few don't).
Anker makes a quality product. Better yet, they back it up with outstanding customer service. I personally own 3 Anker battery packs.

You don't need to carry around a ridiculous charger like these if you have a swappable battery 0 to 100% charge in mere seconds
Actually, you don't need to carry a charger OR an extra battery if you have a phone that can go all day and night.
Just sayin! ;)
I used to carry a LG G4 with an extra battery in pocket. Now carry a Note 5 and the battery lasts as much as LG G4 with 2 batteries even when both LG and Note use a 3000mah.
This is useful for more than just phones. If you carry around a tablet and/or other devices that can charge via USB then it is helpful.
How long do these power banks hold their charge? If I were to go camping for a week or so, would they hold the charge long enough that I could recharge my phone/camera once or twice throughout the trip and it'd be fine or does some of the power leak out over a few days?
I have an Anker 20000 MaH battery pack. After charging it fully, I've noticed that it holds it's charge for several weeks at the least. I believe that you could absolutely take one of these in the field as you described with success.
Most manufacturers recommend that you top them off every 3 months, but they will hold at 70% for several months after that.
If I don't use one of my power banks for a month, I usually find it still full.

Thank you both for your replies.
I have a 12000 mah rechargeable bank for my phone. It charges my phone 3-4 times which is good enough for me & holds its charge for 6 months.
