Quite heavy case with no strap means you're not going to want to carry this around in your hands. I previously had the $24 carry case and after swapping to this case I'm probably going to keep it permanently in a backpack from now on.
Charging the case is fine, but charging the switch borders on annoying. The case battery can be charged with the case closed, but the case must be open and turned on for it to charge the Switch. First impression of it feels like it charges the switch slower than using the Nintendo adaptor (S8 adaptor with 5V/2A rating, using the cable provided by the case).
The 5000mAh battery is larger than the Switch's internal battery, but from experience don't expect it to double the lifespan of your Switch. From near dead the case wasn't able to charge the Switch fully before depleting.
No adaptor is provided, and you cannot charge it using the Switch's charging adaptor. You must find your own USB charger or try your luck plugging it into your PC. Uses micro-USB to charge the case which is quite disappointing if you were hoping to charge your Switch, case and USB-C devices (S8-) with one adaptor/cable combo.
Not a good case for protecting your switch from water or impact. It's basically a hard-shell battery case. Rubber straps on the inside of the case about 3mm thick to prevent movement/scratching inside the case. Decent build quality, nice feel. Outer case is a rubber material which feels nice and resists sliding, but will be prone to scratches easily that won't come off.
Switch is secure in the case, and is easy to insert/remove. Case opens easily but doesn't feel satisfying/assuring when you close it – pressure is required to shut it correctly and there is no feedback to let you know it is closed tightly.
The inner USB-C cable is long enough to wrap all the way around the switch – which is a decent length – but it's a bit annoying to wrap up every time to pack it back up again. Secured only by a few notches around the edges to keep it in place. I often pull the cable out by accident while I'm trying to plug it into the Switch as I sit it back in the case. Average quality cable, it's plastic.
Kickstand has 2 good angles and feels good once set up but is a bit wobbly in assembly. Will slam on the Switch screen when you shut the case if you forget to snap it back in place. Build quality of the kickstand is.. Less than impressive.
12 game card storage only if you stack two per slot, which means only 6 cards are visible. Significant pressure is required to insert/remove the game cards, but appears to be quite secure in the case once inserted.
It's alright, I'm happy with it but I won't be raving about it to my friends.
