Best portable power bank (slim, lots of juice, and built in cable)
4 Stars
Best portable power bank (slim, lots of juice, and built in cable)
I love this little power bank. This is the slimmest power bank that gives me 90 % on a full charge. The only thing I did like is the micro usb input but honestly it’s not that bad I just wish it were type c, and the included adapters for iPhone are usable but I upgraded to the official apple adapter. The best thing is that this charger can fit the OEM adapter so it’s really convenient and the pass through charging is a plus. I use this power bank to charger my Apple Watch and iPhone ( SE 2020) when im not near a plug. This is the perfect charger for $12. It charges my iPhone from 10 % to 90 %. And it gives my Apple Watch around 5 charges max. Disclaimer: I use the Ifory Apple Watch charger adapter to charge my Apple Watch with this portable power bank if your looking for the best Apple Watch charger that’s the one to go for ;)
