Anker Power 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 Series

Bought one of these to replace Charmast version which died. It works perfectly - very convenient when slotted into the Lightning socket, and very easy to keep in a pocket when not. An extra couple of features over the Charmast - the Lightning connector folds down when not in use, so a sleeker design, and it stops charging (all the lights go off) when my iPhone is fully charged, so it doesn't try to overcharge. As the Lightning connecter is now obsolete now that Apple have adopted USB-C, I have bought a second one as a spare.

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).

I own many Anker products and I’ve waited a few months to review this. I purchased two for my children so that they had extra charge for emergencies. Both units failed in the first month and after some back and forth with Anker, both were replaced. 4 and 5 months later both units failed again and did not deliver any charge to the phones. There is definitely a quality issue with these and I would look elsewhere instead of buying these.

This is a very good unit but, depending on whether you use a case, or which case you use, it might not plug in.It has a very decent capacity, is easily charged and will charge the phone up pretty quickly. But beware of the thickness of the slot in any case you use.

I’m super happy with the Anker Nano Power Bank! I’ve had this for 7 months and it’s still going strong. Its compact size makes it incredibly easy to travel with. The build quality is outstanding— sleek and well-designed. It’s a perfect blend of portability, performance, and quality.Highly recommend it!

Great!Bought to replace missing iwalk battery charger.They no longer have this available for lightning connection. This is better as folds neatly.

This is a great little power bank. Easy to use, charge lasts a long time, and takes up very little space as will easily fit in a pocket.

Great product on first use. Very compact design, easy to use. But 7 months after purchase it does not work at all! Customer Support is very, very poor. No response to phone calls, told to email with a form that took 30 minutes to fill with photos and proof of purchase. Waste of time, buy another brand!!
