AnkerPowerCore 5,000mAh Portable Charger, Ultra-Compact 5K External Battery with Fast-Charging Technology, 1 USB-A Port, for iPhone, iPad, Samsung Galaxy and MoreClimatePartner certified

This impressively small power bank fits into a standard (Men's) pocket. There is some heft, which is to be expected. Micro USB is a small annoyance, but ultimately manageable. USB A is also an antiquated design when considering both ports could be replaced by a single USB-C input/output port.Small issues are surmountable considering the general lack of power banks which will actually fit in a pocket. 5000 mAh is enough for one charge of the One Plus Open's considerable battery capacity. I'm old enough to remember carrying around a spare battery to swap in on the fly, which is essentially impossible now except for the cheaper smartphones with limited functionality. Spare lithium ion batteries can be fit into a wallet, but don't hold their charge very well.Only time will dictate the longevity of this power bank. It feels robust with the standard metal construction Anker is known for. The bank charges quickly enough, but certainly won't charge from zero to one hundred in less than an hour. Likewise, the power coming from the device is enough to charge a phone at a steady rate.Ultimately this spare battery is highly useful in many different situations. Hopefully it will last longer than a few months of infrequent use.

Easy to charge

Recently replaced older, small powerbank. Fits nicely in handbag, backpack, etc. I have used it for family members to charge on the go. Recharges to full power in a short period of time. Very pleased.

First off I like Anker products. I have a few now the 10k wireless charger, a few cables, one cable that I tried to warranty and they never got back to me on. A larger 20k metro essential. But it all started with the power core 5k my first ever Anker product it’s time to retire it.I ordered it because I didn’t like the early battery degradation and overheating I would could on my portable devices especially when leaving them plugged in over night. With all the safety feature’s implemented in this little thing it’s what got me to buy, never having to worry about my devices overcharging or overheating.I purchased it in 2018 March and have been using it regularly since. I fondly remember times where I’m concerned I would run out of battery on my phone on long road trips and such and here this little thing was to the rescue saving my device and sometimes part of a family members device as well. I honestly didn’t know what to expect at the time when I picked it up for 15$ back than. I’ve used to power a large assortment of devices at this point to name a few- to charge an electric toothbrush, some usb powered speakers, I was surprised it could power them, many a phone, a few tablets and iPads, etc. The thing trooped on regardless of the dings and scratches it ended up getting from daily use it never stopped. It’s built surprisingly tough. It’s been with me through a lot and it could sit on a shelf for a month or two between charges and still hold a decent charge after all that time idle. I remember a time I was out doing snow and using it to charge my phone as I was listening to music and the battery itself became like a little hand warmer which I throughly enjoyed, thing itself may have gotten a bit hot sometimes but the heat would dissipate quickly.Sadly all good things eventually come to an end. Just recently I had been using it exclusively to recharge my toothbrush and leaving it in the bathroom for a few months it trooping through cycles of people taking hot humid showers. A family member “borrowed without asking” it and used it for their own device and upon them giving it back to me it was out of charge so I did what I’d usually do plug it in to charge overnight. This morning after my toothbrush indicated to me that the battery needed charging I went to plug it in as always and none of the lights came on, on the Anker battery. The button on the device stopped working as well. The lights came on with it plugged into the wall through the input port but the output as far as I have been able to tell has finally given out. Not saying it isn’t my family members fault and they somehow managed to break it but. . . I’ll be remaining open on that thought I plan on having them reimburse me for it considering that they used it last.All in all I wholeheartedly recommend this little device, maybe they’re not as good as they used to be I can’t say I only have my mileage with the one device of this model. So thank you Anker 5k for 5 years of power in many a different circumstance.
