Recommendation for a portable phone charger

I bought an Inui powerbank from Amazon and it worked very well. Anker is also very good. 10,000 mAH is good for about two or three charges of a phone. A larger capacity battery will weigh more and cost more accordingly. The key thing to look for is PD and QC fast charging.

I was gifted an Anker 10,000 for Christmas which was what I'd asked for. I've tried it a couple of times since opening it and it charges my iPhone quickly. It weighs about 8oz which is heavier than I liked but it does have the 2+ charges which the smaller ones don't have.

I have a 2-year old iPhone and started running out of juice in Venice using CityMapper to navigate myself around. It was at that time that I realized I needed a power bank.

Note to others who might not always read the small print:
I had to buy a second power bank because I didn't know that packing it away between trips would lead to it's death. They need to be used/charged every few months.

hey hey schillpaw
i have 2, one a gift another i bought
poweradd slim 2 5000mAh
it looks like a fat lipstick tube, carry in my bag, not that heavy
belkin 10000mAh
not that heavy but i need different cable cords to plug in to charge (not charger/phone savvy) but it works for me. i learned the hard way when my cord wouldn't fit LOL. like them both, good luck
aloha

You should only buy the battery capacity that you need or use. I only buy a new battery when the old battery wears out. Otherwise, it would be like carrying a second spare tire in case your first spare tire develops a leak. All rechargeable batteries will deteriorate over time. There's good chance that if you buy two batteries at the same time, by the time the first battery wears out the second will also be on its last legs.

If you only want something to charge an iPhone, what about a battery case? I bought this one from Alpatronix based on a recommendation from someone on this forum and really liked it.

we've always used Anker PowerBanks - sometimes cheaper on amazon -vs- anker website

I am another Anker fan. Their portable power banks are very reliable and charge quickly. You can buy them on their website or on Amazon, but you might find some deals on Costconext.com if you’re a member of Costco.

No specific unit to recommend, but a couple thoughts about what to keep an eye out for;

Around 5,000 mAh is my ideal portable battery size. It’s more than one charge of my iPhone XS, which is plenty for me on a day out and about. I’m a fairly heavy user. Bigger batteries are just more weight and bulk to carry.

Input and and output jack types are a consideration. USB-A and Micro USB are the familiar and ubiquitous. USB-C offers much faster charging (both battey-to-phone and battery itself), and it’s the format all devices are (slowly) switching to. But it you don’t have those cables yet, it could represent further initial outlay. And carrying more cables while we have different things charging different ways.

If you are a COSTCO member, check out their myCharge POWER HUB All-In-One Charger. I was on a seven-day wilderness camping trip last month with no access to electricity and kept my phone charged with this unit. I love it as it has built in charger cables for phone charging as well as built in prongs for charging it. You don’t need to worry about carrying cords. Plus, it is quite a bit lighter than my Anker PowerCore 2000 which I took as a back-up and never used. The Anker requires separate cords and a block to plug into an outlet. Too much hassle.

Do you need a charger or a portable battery? The better sources of information are CNET, Wired, and the likes that include longer term experience and abusive testing.

I interpreted the question as needing a phone charger rather than a power bank.
We've found the base 12amp apple charger that used to come with the iPad serves most needs along with the Apple World Travel Adapter Kit

I think a lot of people are unfamiliar with the term "power bank" and use the term "portable charger" instead.

Any by Anker. Love the brand.
