I love the fact that it can stay inside the webbed pouch and I never have to touch any button to turn it on. It just knows a device is plugged in and starts charging it.
This thing will even charge at 2.2A according to my meter (see photo). I've owned plenty of other USB batteries and they've all topped out at a little over 1 amp, so despite this Anker having double the capacity of my older ones, it charges in the same amount of time.
- the overall pack is a bit bulkier than I would have thought. The description talks about it fitting well in a purse or a bit bigger than a phone, it's a good deal larger than my iphone or my husband's moto x so I'm not sure what kind of old cell phone people are talking about. It's a bit on the heavy side too
- that said, it charges up my ipad though not as fast as a wall charger. I haven't measured out the time of how fast it charges, but it's not as fast for the phone or ipad as the wall charger. That said it's a fair site faster than usb connected to my laptop, probably similar to my car charger actually
- I like the lights on the bottom. Other battery chargers I've seen doesn't tell you when the juice is depleting so this is a nice touch
- One thing I find annoying about this is that it doesn't automatically seem to sense when something needs charging. You have to push the button at the bottom in order to make sure that it charges, and sometimes I notice at least on mine it can be a bit finicky sometimes turning off when what I'm charging is still not completely charged. That said I would say in 98% of the cases, it's fine.
- I brought it on a camping trip recently and I was quite popular as it ended up charging about 4 different phones to completion.
- I like the fact that it charges with a micro usb port, because it ends up being convenient to just keep one micro usb cord to charge my husband's phone but also to charge this.
I'd also like to note that I'd like to get on the list to get free stuff, but i guess I don't write enough reviews. Maybe one day.
why is this thing the s***? with my s5 in pocket, short usb cord, and galaxy s5 im right around an inch of pocket bulk yet it charges my device quickly. should i need to charge 2 devices at once it could do that.
i have an olight s10r which came with battery, charging base, and the light. i can plug this into the charging base to charge my light on the go, throw another usb cord in that charging base to charge another device, and throw another usb cord in the OTHER smart port to charge ANOTHER device like my tablet or somebody elses phone or light alllll at the same time. might not be the fastest with all that s*** hooked up but you could do it. its also one of the slimmest and very light. possibly best bang for the buck portable charger out there.
anker also has quick chargers right now so im going to find out if the e3 can take advantage of that
Anker kindly contacted me and they're sending out a replacement, they got back to me the same day I wrote this review and that's amazing customer service! I've always bought their iphone chargers and micro usb and never had a problem so I more than likely got a faulty portable charger. It's amazing having peace of mind buying something and knowing customer service pulls through right away to make things right. Thank you Anker! You guys just got a lifetime customer.
First off I received this item on June 7th 2017, so last month and it worked great. I turned it on today and it turns on but doesn't charge. Yes I've tried different cables. I charged it up, took it off the charger but it won't charge my phone (phone charges fine with outlet charger) It's disappointing because I had high hopes for this, with all of the great reviews and how durable it was yet I only use this in the car for trips or maybe a couple times a week and it's already not working. I gave it 2 stars because it was great when it worked. It charged quickly unlike most on the market. I don't know if i somehow got a defective one maybe?
