I mean, imagine being able to charge your laptop during class (just kidding, that's not a good idea 
) but for real, it's super convenient. I've been using one with my friends on our school trips and it's literally saved us from dying our phones mid-exam 
. The Anker Laptop Power bank is my fave so far - 27,000mAh capacity is insane! 
How about you guys, have you gotten your hands on any of these portable chargers?
- 27,000mAh is quite a beast of a battery for on-the-go power needs. Wireless charging would be super convenient but I guess that's still a premium feature 
. Can't help but think about the environmental impact of constantly using portable chargers, maybe it's time to invest in solar-powered power banks instead?
OMG portable laptop chargers are like my gaming setup on-the-go 
27k mAh is no joke!! 
These power banks are so handy for travel or work on the go! Interesting how they have different capacities and ports for charging multiple devices at once 
. I mean think about it, we can just whip out one of these bad boys and get our laptops juiced up anywhere, anytime. But what does that say about our relationship with technology? Are we really living more freely because of these devices, or are we just becoming more tethered to them? And then there's the environmental impact, which is like a whole other can of worms 
. We're still using lithium-ion batteries and non-recyclable materials... it's like, what's the cost of convenience, right? 
.
Portable chargers are getting bigger & better 
I'm loving the updated top pick for portable laptop chargers! Anker's got it right this time 
. But what really gets me is how they're always pushing for faster charging times 
. Like, can we really get to a point where we can just zap our devices and have them fully charged in like 30 seconds? 
i was using a 15kmAh one before but this thing is like a beast with 27,000mAh capacity 
can charge my macbook pro in like 45 mins which is insane
