This Gudetama MagSafe charger, which I bought via Amazon to match with the Gudetama 14 Pro Max phone case, is adorable and works best when connected directly to the iPhone itself. I had issues with constant disconnections and reconnections when attached on the Gudetama 14 Pro Max case itself, but I noticed that it's likely a flaw with the phone case (which I have reviewed separately), not the charger.
If you love Gudetama, there's no reason NOT to get this adorable little MagSafe charger.
