AnkerPower Bank, 621 Power Bank with Built-In Lightning Connector, 5,000mAh MFi Certified 12W Portable Charger, Compatible with iPhone 14/14 Pro/14 Plus/14 Pro Max, iPhone 13 and 12 SeriesClimatePartner certified

Doesn't take long to charge the power bank (requires a USB-C cable to charge the power bank, despite the power bank being compatible with charging devices that require a lightning cable). Depending on if you're using your device while charging, the power bank sometimes runs out of charge quickly, but usually it's okay. It's easy to see how much charge is left (click the round button on the left side of the power bank and it will light up on the front - 4 lights being fully charged). It doesn't overheat, it's very handy as it's nice and small so great for using when out and about. Good value for money, especially as it's Anker (a well known tech brand).

Charges quickly and works great.

When I purchased this power bank, it worked well for a short amount of time before randomly dying. It took no damage or drops, it just stopped outputting charge to any phone connected to it. It would receive power just fine, it just couldn't output any.I contacted Anker support about this and to their credit, they sent a second unit free of charge - but that one was dead on arrival. Same issue as the first one; I could charge the power bank just fine, but when connecting a phone to it, it wouldn't output any charge at all. But this one didn't die after a short time like the original one; it was like this when I first got it.So they sent out a third unit. This one was also dead on arrival. Exact same issue.Amazingly, they sent out a 4th unit despite me saying that it might be better to give up and just refund the original unit. This 4th one actually worked!For a few months.It has since died, having the exact same issue as the previous 3 units. This one lasted longer than the first one, but still - for 4 of 4 to have this same problem, something has to be seriously wrong with their quality control.I treated the devices with care - no drops, no bangs, no pressure put on it, no over charging.Credit where credit's due to the Anker support team as they were more than happy to send out unit after unit, but the product itself is just unacceptable.

Excellent bit of kit. Wanted something quite small to fit into v. small handbag. Charges fast, and great backup for my aging iPhone.

Purchased last year for £29.99 but after a year stop charging my phone completely though the power bank is fully charged. Could be the built-in lighting connector becomes defective .Nice design , small and cable-free and it’s Anker (trusted name) . Contacted the customer support team and after explaining the issue and providing evidence (photo , proof of purchase ) they sent a replacement.I have few Anker that are working perfectly for years and this issue does not turn me off .There’s 18 month warranty, and the customer support team is fantastic.

The product is designed very well, compact and as such is handy to carry around for emergency phone charging.

Great for travelling as it’s perfect size for a small bag and fits in your pocket nicely. Charges quick and no hassle, however, mine broke after a year’s use. Because the connector is very mobile and prone to jiggling a lot, the connector on mine unfortunately broke and not charging my phone anymore.One thing to remember when using this product especially if you use it a lot.It has that same issue with power cables wherein after how many months or years of use, the adaptor no longer works properly.

This power bank has saved me a number of times. The charge lasts well and recharges my phone quickly. I def prefer this to some of the mag charges.The port clips into your phone nicely. Great value for money.
