I was visiting Japan and saw them having these banks with built in charger. Especially their 7 eleven chargers.
I’ve always had problems finding a proper charger/cable to quickly charge the bank.
Is there any better alternatives/suggestions on what to buy?
Pretty neat to have the wall plug built in. But only 1800mah for that big of a device! And it only charges at 600mah so it will charge slow regardless. I’d get a power bank cabale of charging at a minimum of 1A. 2A is better. Pair it with a fast 2.4A usb wall charger. Not idea as it isnt all in one but i think it is much better than that combo.
7e has a variety of choices that are bigger in size. I am currently thinking if I should diy one myself
Be aware them. Good ac-dc supply board is bigger than whole bank. Small circuits are not fully insulated from ac, it is not safety to use such things.
Anker makes one, called PowerCore Fusion. But its 5000mAh, so not the largest capacity.
Hyperjuice used to make several, but that's discontinued.
