Massive power: Best of the biggest power banks and portable battery packs

Massive power: Best of the biggest power banks and portable battery packs
Remember walkmans? They sparked quite a revolution back in the day by letting us listen to our super awesome megamix tapes even while on the go. Most walkman models ran on a couple of AA batteries which could be easily replaced when exhausted.

Smartphone batteries, however, are a bit different from garden variety AA cells. They have to be recharged regularly, and there's not always a power outlet nearby. The solution? Get a power bank! These portable battery packs are extremely convenient as they provide emergency power when we need it. And while they come in a broad range of sizes, today we'll focus on the largest among them.

In the slideshow below we've put together a bunch of super-sized power banks – the kind you'd want to have in your backpack while traveling. These are large enough to recharge a smartphone multiple times, while their multiple USB outputs allow you to recharge a couple of devices simultaneously. Check them out!

too bad the chinese will walk all over this thing , double the battery life at half the price, can't beat that. battery life will be puny , if QHD rumors are true. the oneplus 2 & Mi6 will have a much bigger battery. thinness is so overrated

Actually if you compare with other high quality brands like rav power, mophie, Lepow, tylt and so on.... Anker is amazingly priced. I am very satisfied with their phone batteries and portal chargers. Also anyone who i suggested to, says its better than oem battery and portal charger don't deplete like other brands.

Bought the 10400mAh MiBank and it's pretty good, would definitely get the 16000~mAh version but it wasn't on special. I guess 10400 is enough for me.

Here is a WP & iPad user, and I don't need these sh*ts as both are compatible for the whole day. I use WP for capturing photos and chatting apps, and iPad for browsing & social networking.

The Incipio Smart should be Gold crusted to sell at that price, for the capacity..WTF..

Why nobody mention about - the effective mAh that you can EXTRACT from the battery. The best ones comes to 80-90%, common is between 70-80% and lower quality only 6%. That means for a 10000 mAh you get only 6000 mAh. - the weight Why do you need a powerbank these size? Because you need it when you travel around or gone for a long time without power. Therefore weight is important. - the charging time Depending on the input and size it charges between 6 hrs to 32 hrs. If your imput is 1 mAh it really matters between 8 or 16 hrs.

I knew already....industrial standard was 35% loss...why bother ?

Because the battery cells inside are 3.7V, while the power bank output is 5V. Say 10,000mAh batter inside, 3.7*10,000 = X*5, due to the law of energy conservation. You got X is 7,400 or 74% real power to extract while there is 0 loss during the 3.7V to 5V transition. Think about the loss there say 10%, then you go 74%*90%= 66.6%. Here is the 35% loss comes. Check my blog kaayee.com for more info.

I have 2 Sony portable charger Sony CP V5 and CP B20. I always carry CP V5 because the size (72.0 x 127.0 x 12.2 mm) is small enough to be in my pocket. And I use the CP B20 as an emergency power source because the capacity is quite massive 20,000mAh and 6.9A maximum output. It doesn't have many fancy features but i always prefer japanese/american brand because usually they have a better quality and i have a Sony phone. I really wanted to prove whether their claims are true or not. "Sony claims that their lithium-polymer rechargeable battery retains more than 90% of its capacity at 1,000 charges"

CP B20 is great, but unfortunaltely Input is only 1.5A (i.e. too long too charged). Recent power banks have 2A Input.

We do not need always a big capacity power bank. What matters is what is our requirement. For better resources about power banks go to powerbanky.com
