After a month of testing, I determined Aukey 20000mAh is the best portable power bank because of its versatility and Apple Lightning port. Anker has a stellar reputation and the same battery power, but only two USB ports. However, you can’t go wrong with either.
I’ll compare and contrast two power banks (Aukey vs. Anker) by evaluating four categories: charging devices, recharging, form factor, and company reputation.
Aukey 20000mAh (PB-Y14)
- Charging Devices: You can charge three devices at once via USB A or USB C.
- Recharging Power Pack: There are three different methods of recharging the Aukey power pack: micro USB, USB A, and USB C.
- Form Factor: It’s only 0.6" thick, but it’s much longer and broader than Anker.
- Company Reputation: Aukey’s reputation on the internet isn’t as strong as Anker’s, but they have a 24-month warranty.
Best for you if...
You’re an iPhone or MacBook user or charge your phone with USB C. The Lightning port requires fewer cables, which is helpful when you’re traveling. If you’re a MacBook user, you can fully recharge Aukey with your USB C cable in six hours, making it the fastest recharge time of any power pack. While it won’t charge your MacBook quickly, it’ll give you a few extra hours of MacBook use too.
Anker PowerCore 20100
- Charging Devices: There are two USB outputs. You can charge two devices at once.
- Recharging Power Pack: The only way to charge is with a micro USB cord, which is included.
- Form Factor: It’s 2" smaller, can fit in a pocket and doesn’t collect fingerprints.
- Company Reputation: Anker has the best reputation of all battery manufacturers and includes an 18-month warranty.
Best for you if...
You want to buy from a company with the best reputation in the phone accessory business or your phone already uses a micro USB to charge. Anker recharges via micro USB cord which means it’ll take 10-20 hours to recharge and you’ll have to bring an extra cord along if you don’t have a micro USB. You only get two USB ports, but it’ll fit in your pocket better than Aukey.
- I tried a RavPower power bank too and it worked as well as Aukey and Anker, but I couldn’t write any more about batteries without getting nitpicky. Anker and Aukey are the most reputable brands, so that’s what I’m recommending.
- I can’t speak to longevity yet because I’ve only used them for four months, but I’ll update this post in time.
- They could both improve upon the battery power display because they only show remaining power with four led lights. I’d like something more specific.
Charging Devices (A):
- The battery size is 20000mAh.
- Aukey’s estimated charges came close to aligning with my real life tests. There are a lot of variables, including the time between charges, the number of charge cycles (i.e., battery health), number of devices plugged in, and how they’re plugged in.
- I consistently got four full iPhone X charges (from ~5% to 100%).
- I consistently got six full iPhone 8 charges (from ~5% to 100%).
- I consistently got one-and-a-half iPad charges.
- It won’t charge my MacBook Pro while I use it, but it’ll maintain the battery percentage. It basically extends my MacBook’s battery an extra 5-6 hours.
- There are four output ports: three standard USB ports and one USB C port to charge your devices.
- You can charge three devices at once.
Recharging Power Pack (A+):
- There are three different methods of recharging the Aukey power pack: micro USB, USB A, and USB C. Ports is where Aukey wins by a landslide.
- Lightning and USB C are significant if you’re an Apple nerd because you won’t have to bring as many cables with you. You can recharge the Aukey power pack with your MacBook’s USB C, or your iPhone’s Lightning cable. You can ditch the Micro USB.
- It has the potential to be recharged in six hours with USB C, but it’d take close to 20 hours with an iPhone Lightning cable.
Form Factor (B):
- It’s only 0.6 inches thick, but it’s much longer and broader than Anker. It reminds me of the huge Texas Instruments calculators that we used in school.
- It scratches easier and leaves more fingerprints than Anker.
- I appreciate this form factor better because I’m not putting something this heavy in my pocket anyway. It sits level to my MacBook on my desk.
Company Reputation (B):
- Aukey’s reputation on the internet isn’t as strong as Anker’s, but it’s not bad. They’re just not well-known.
- You get a 24-month warranty (an additional six months compared to Anker).
- It’s a smaller sample size than Anker, but their power banks all have a rating of at least 4.4 on Amazon.
Charging Devices (B):
- The battery size is 20100mAh.
- My recharged times were similar to advertising.
- With a full power pack, I could charge iPhone X from 5% to 100% four times and iPhone 8 six times.
- I could recharge my iPad a little over one time.
- There are two USB outputs, and you can recharge two devices at once.
Recharging Power Pack (B):
- The only way to charge is with a micro USB cord which is included.
- It’ll take 20 hours to charge the battery pack with a typical 1 Amp phone charger (iPhone charging brick) or 10 hours with a 2 Amp charger.
Form Factor (B):
- Anker features more of a matte finish and is better at not leaving fingerprints.
- You’re not going to want to put this in your pocket because it weighs 12.5oz, but unlike Aukey, it can fit in a pocket if you wanted to because it’s only two inches wide.
- It’s 1.5oz lighter than Aukey.
Company Reputation (A+):
- Anker has the best reputation of all portable battery manufacturers. When reading over the forums and Reddit, it was tough to find a bad thing said about them.
- The version I bought (PowerCore 20100) has 4.6 stars on Amazon with over 12,000 reviews. Anker’s other products follow this pattern too.
- All Anker power packs and portable batteries come with an 18-month warranty.
