What Battery Bank Should You Buy? 

Buy 2 power banks and have them charge each other, that always turns out well.

Everybody: iPhone 7, headphone jack, apple sucks, apple's great etc... Linus: BATTERY BANKS BITCHES

How to buy battery banks: Step 1. Buy the biggest Anker you can get done.

"You just uh..whip it out of your pocket and BAM!" And what? You get a painful reminder that you haven't exchanged your Note 7 yet? Hah! Buuurn.

I'm early, better make a joke... Iphone 7 is revolutionary

it is clear that linus was not meant to do this tech quickie originally lol

so pretty much he didn't answer the question of the video title...

Did you just refer to yourself in third person?

Anker 15000mAh (pre powercore) has been going strong for 4 years now. In addition to a Project Fi gift power bank w/ 5000mAh I've owned several brands over the years, but Anker has the best reliability, and best customer service I've experienced so far.

RIP Pokémon GO 2016-2016

Dear Linus & Team, thank you for making these videos. They're concise, informative and perfect for us modern viewers! I love your work so much - keep up the good productions!

I used your earlier video and bought an Anker Battery Bank. I couldn't be happier with the results. Thanks for all the advice you give!

Linus: OVER 9,000!!!!!!!!! Battery: Explodes!

from experience, I'll always stick with anker batteries. they have never let me down

I use an Anker Astro Pro 2 20,000mAh every day. I got it about 2 years ago and it still holds up to my demands. I have discharged it completely in less than a day, but I was charging a PSVita and a phone for a friend while playing Ingress for multiple hours (before it's significant battery optimizations; constant high drain application of the tech).

My go-to everyday power bank has been the Anker PowerCore fushion 2in1. It doubles as my wall brick aswell which is nice. I did an unboxing video of it and so far it's been my favorite. I'll do a review video after I've used it for a few more months.

Anker powercore 10000 (non quick charge 3.0) best battery bank I've ever had.

The sound at 0:15 sounds just like the hungry sound from Starbound.

Romoss solo 5 is great, I've got a couple of them. No frills, no flashlight to accidentally turn on while in your bag, good shape, ideal outlet placement. They just work. I can comfortably keep my phone and the powerbank in one pocket while the phone charges too, which matters to me.

I have the 12,000mAh Cheero that Linus covered years ago. It will works like a beast and can charge my Note 5 from dead to full multiple times.

Just built my own one using 8 18650 batterys. Works very well.

I always get Anker stuff, seems to be a solid cost/quality balance in my experience.

omg, Linus trying to keep it together during the Audible promo was priceless.

Love the on the fly charge correction. Nailed it.

bro, how the fuq did you know that I'm in the market for a new giant hamster wheel?

I use Anker Usb type C 20100 mAh power bank for my Google Pixel XL and man... I love it. It's fast and reliable. Good work Anker.

I strongly recommend Samsungs own power banks. It was $20 more than some third-party one with the same capacity, but the build quality and quick charge functionality easily makes up for it.

If u put a bunch of AAA battery in a safe Would dat be a Power bank?

Today was so funny in my computing class, my teacher said "class we are going to watch a video" and she put on RU-vid and put on TechQuiky

3:24 - Did you just make a date rape roofies joke? Geez you guys are dark today xD

this episode need an update. many now have usb-c with usb-pd. my bank even does 45w. (my phone only takes 25w, but future proofing is nice).

Linus, i think another important point is how quickly the actual battery bank itself is to charge; the input specs as well as the output specs. Its useful to have a 20000mAh battery bank but if it only charges at 0.5A it'll take days for the battery bank to charge and defeats the purpose

mAh is not unit of energy it is a unit of charge 1A is 1C/s 1Ah is 3600 C mAh at a specific voltage is a unit of energy because P = IV and E=Pt

"Linus published a video" LTT is using a Linus bot to read TechQuickies confirmed.

I Chose my portable battery as it cost 18€ for 20000Mah and happened to have 2 integrated leds as flash light i have 1 1.2amp USB port and 2 2.3 amp USB ports and i am very happy with it. I liked your video as usual

Linus, got any new recommendations for high capacity power banks? Maybe that'll work with laptops?

im pretty sure linus was trying not to laugh at that audio book suggestion.

Most of these power banks use 18650 cells, these are around the size of a roll of quarters / 3quids worth of 10p. They also tend to be around 2000mah. If you see a battery thats only 1 cell ish in size and says its higher (say 500+mah) then its bullshit. Spend the extra and get a 2cell unit, rather than a smaller one made of lies.

I got Intenso 10k amh with A3 output for a price of 23€ quite ok I would say but I realize that it’s actual capacity might be ~5-7k taking into account the power loss from other factors as well.

did everyone miss at 3:23 Linus is promoting "DATE RAPE DRUGS!" WTF!

Just watching this in 2022....that Russia joke at the end hits different now

DO NOT BUY 1 AMP BATTERY BANKS Got it? ok, good!

Linus, i can suggest some highly rated audio books, Try: the power of five - anthony horowitz Nightmare series - stephen leather Day by day armageddon - JL borne Shatter - michael robotham Been a fan of audible for years now great for long journeys in the car

That outlaw's kiss part was priceless, he had no idea that was coming lol

"Linus published a video" that's me!" - Nice recovery ;)

4:28 I hope I'm not the only one that caught the Napoleon reference

Get the 20AHr from Aukey. No quick charge but it gives you 1 A and 2.1 A in two separate USB ports. It is big and heavy but if you go camping for a weekend it will work great for you. And since it's an older model it's actually cheaper. I got mine for $23 last year.

What was failed to be mentioned in this video, is the input. If you have a large powerbank, make sure it supports 2amp input, otherwise it will take forever to charge.

2:51 Linus published a video... that's me!

mWh is a far better unit to use here as there's always manufacturers that are going to state the (exagge)rated mAh of the battery cells themselves, which can be at a different volts so using mWh avoids any confusion. And let's be clear, 100Wh or 20000mAh rated at 5V output is the absolute maximum you will find as that is the legal limit for a lithium based battery. Anymore than that, and you can bet the rating is false.

Waited for a new version of this for a while now

I have the zerolemon slimjuice (18,600 mAh) battery bank. It's not currently available on amazon canada though, but would definitely recommend it regardless. have been using ZL batteries since galaxy s3 and they have never let me down

Title should be: what is a power bank

3:23 is that like a date rape joke? haha shit got real out of no where

Im on the go alot and i still play some pokemon go with friends and i picked up the aukey 20000mah battery. Not only is the capacity big enough for about 10 charges but it has 2 outputs and you can charge with micro usb or lightning, which is very convenient for iphone users.

I am always confuse about how much amp needed for each of my device. I have charger & powerbank with multiple output but i do not know how to identify if my device are charging as it should. Can you do a video on how we can calculate & optimize the output for our charger/ powerbank? Thanks

Hey Linus you should try to put a pc into a car!

1:41 IT'S OVER 9000!!!!11!

I use a ravpower 13400 mAh battery pack. Has 2 ports, one 2.1a and the other 2.4a. Has a very helpful charging indicator

I've been using my Cheero Power Plus (12000mAh) for about 2 years on phones and tablets and it's been quite reliable.

If your phone is dead after a few hours you need a new phone, mine lasts all day and when I plug it in for night it is at like 70%

Who else saw this even though they owned a portable battery just because of linus.

Weird question-I’m looking to use one of these to run usb air pumps on my aquariums as a backup during power outages-not charge it, run it while connected. Can these banks run things or just recharge things?

For my Tablet I use Tecknet, 9000millamp with a 1 and 2,5 amp output, my other powerbank Is a DB POWER one which can jumpstart a CAR... I use that for jumpstarting my motorcycle, it's part of my breakdown kit...

the "dont forget these" ffs linus 03:26

I didn't get that joke about Russia at the end 😕

what power bank you should buy? the one with note 7's battery

I've just bought a 50000mah battery bank which is actually a laptop battery bank, it has up to 5amp output via 19v laptop charger and 2.1 amp 5v USB output. it's very handy when camping.

Anker 20,000 mah best brand and best price.

3:24 was this a bill cosby joke?

WOW, Great video, you rock, you make video that are interesting to watch. Good audio clear video. Great subject I learn a lot in just a short time.

I use the juice power station (11200mah) dual usb ports 2.4a + 1a, this keeps me going for a few days without having to recharge again, even using them to charge my phone, Bluetooth speakers, headphones, even the rechargeable lights on my mtb.. more than ideal for camping

Were those pills a date rape joke?

mAh is a unit of charge, not energy. Do your homework Linus.

I got a 50,000 mAh battery pack to take camping. It's for powering campsite LEDs... it's awesome! That's the largest I could find, before getting into scooter and motorcycle sized batteries. Plus, those don't have 3 to 4 USB ports either.

We need an updated version of this

a date rape joke really?!?!?!

My recommendation is to not make date rape jokes.

Ampare is a unit of current which is defined as charging through an area per unit time, so current times time is charge that's why milliampere hours is untitled of charge and not time

Cool video, i like the simple explanation but i want more!

Thanks for telling me what battery bank to buy. Super helpful. If I wanted to figure it out on my own I would have. I'm lazy AF and want you to make my tech decisions for me. Get your shit together Linus!

The 2 amp ones charge faster but the1amp ones have the benefit of keeping your phone powered wile plugged in for longer. This is because when you rapidly discharge a battery to rapidly charge a differint battery more of the energy is wasted, burned off as heat or other inefficiency. 1amp is my preference for this reason.

Great video. And I loved your sense of humor.

So, my phone had a 1300MAH battery and I replaced it with a 1400MAH battery (Which is what my phone was designed for but I lost my battery somehow and had to use an older model's one.) and I'm wondering... How much will that actually help?

you also missed a key part efficiency, some manufacturers advertise their product with the capacity needed to charge the bank, not the charge capacity the bank can hold. mine is advertised as a 10000 mah battery bank, but can only hold 6500 mah due to about 60% efficiency. that info is listed on the bottom of the battery bank. oh, you also need to keep in mind that the 10000 mah (for example) is output actually 10000 mah at 5 volts. this is important as there are devices that use the lesser known 3.6 volt standard, and you will need a transformer to convert the 5 volt output to 3.6 volt. if you only use the battery bank for said 3.6 volt device, then the capacity is not 10000 mah at 5 volt but more like 13800 mah at 3.6 volt (not accounting for the inefficiency of the transformer). that is why i choose to focus on the watthour rating instead.

Except you did not mention the fact that charging your phone with an external battery bank can diminish your device's ability to charge and maintain a proper charge. This is why some of the newer devices like the Galaxies advise you to only charge your phone with the INCLUDED wall plug. Yes, battery banks are great if you get stuck in a bind and your battery is dead but for the long term.. probably not a good idea to always have them plugged into your phone.

Looking for advice in 2019! Camping in a few weeks, using phone to take video / photos on the go!

I feel like you should have put more emphasis on the value of QuickCharge, etc. It's really a night and day difference from a standard 2A battery.

Linus didn't mention anything about charging efficiency. when you charge or use your device, some of the electrical energy is being converted to heat energy. so any battery bank you get will never charge your device as much as advertised. for example of you got a 10000mah battery bank and it's charging efficiency is 80%, that means 20% of that power is being converted into heat and you only have 8000mah of useable power. the more efficient it is the more useable power you have.

Just bought a qualcomm 2 charger. it's on the way and hopefully it improves charging time even faster than before. yay USB C!

what about charging above 50% in Li-pl batteries? wont the resistance increase the higher percentage it goes and in effect last longer to stop at 50 and recharge over and over when it gets low?

Test'em yourself. USB testers start at a little over a dollar for a simple model. I bought a powerbank that had a 1 Ah output and a 2 Ah output. Guess what? The 1 Ah delivered 0.5Ah to a device that prefers 1 Ah, and the 2 Ah delivered 1 Ah to a device that prefers 2 Ah. And I didn't connect both at the same time. It's capabable of delivering more, though. A load and tester went up to over 2 Ah on the 2 Ah port before it crapped out. So why didn't my devices draw more?

My grandma gave me a 1200 mAh battery bank for Christmas that she bought for like $50 on QVC. Tech gifts from elderly are such a bummer. It looks nice though, very shiny. It also comes in a fancy RF blocking wallet that does absolutely nothing to stop people stealing your credit card info like it claims to.

Linus, does quick charging reduces battery life? is charging battery quicker destroys the battery cell itself a lot quicker?

Anker MegGo 622 with magsafe, to not have to remember a cable for charging the phone is a revolution.

Awesomeness, I am getting ready to buy my 1st power bank.

Thanks for this informative techquickie, could your next one be on the other difficult concept you introduced in this video called "cup of water"?

at 2:50 you can tell Linus wasn't supposed to be in this video. bahaha that "Linus, That's me." line killed me

I would enjoy the video thank you what is the best power bank for HP laptop?

Dammit Linus, I have just bought one! Although, there wasn't anything I didn't already know :P . The one I purchased was Samsung's Fast Charging Battery Pack of 10,200 mAh for my Samsung Galaxy S6. For some reason, it's difficult to find a power bank that features rapid charging technology, here in the Netherlands. Most of them tend to support 2.4 A at most - which is 12 Watts (5V x 2.4A). Meanwhile Samsung's implementation can be 15.03 Watts (9V x 1.67 A). I'm not entirely certain if ~3 Watts makes a big difference, but I rather be safe than sorry with a power bank that explicitly supports rapid charging technology. Personally, I would have considered the Anker Powercore 10,000 with Quick Charge 3.0 (the 3.0 portion could come in handy in the future), but I can only seem to order it from Amazon and they don't support Paypal - I don't have a credit card - or my country's own iDeal (like Paypal, but through your own bank). The latter was to be expected as it's not used anywhere outside the country, but only supporting CC's is incredibly annoying. Oh yeah, what can also make a power bank's capacity feel lower is how some of the charge is lost through heat and by converting said charge for the output.
