TL;DR — These are the Best Nintendo Switch Battery Cases:
1. ZeroLemon Extended Charging Case
Best Nintendo Switch Battery Case
ZeroLemon Extended Charging Case
ZeroLemon’s battery pack for the Switch includes a 10,000mAh battery that the company claims will add a righteous 10 hours of runtime to your Switch. Other handy features include a kickstand, MicroUSB port, USB-C port, and a card slot with enough room for three game cartridges. The only potential downside to the ZeroLemon case is its size. Compared to similar battery packs, this particular case is a bit bulky, but that’s par for the course for such a massive battery.
2. Nyko Power Pak
Best Slim Nintendo Switch Battery Case
Nyko Power Pak
The Nyko Power Pak is both slim and lightweight, so it’s perfect for a plane or road trip. The two-part case sports a mid-sized 5,000mAh pack, which should be able to double the battery life of your Switch. Two lock sliders hold the pack’s top and bottom pieces together, preventing accidental bumps from dislodging the battery pack. A USB-C cable is included in the box to let you charge the Power Pak, and four indicator lights let you check its charge level at a glance. Overall it’s a slim battery that doesn’t add much weight to your Switch, nor does it take too big of a chunk out of your wallet.
3. Antank Nintendo Switch Battery Case
Best Mid-Size Nintendo Switch Battery Case
Antank Nintendo Switch Battery Case
The Antank battery case is appropriately named, as it makes your Switch look like an armored truck due to its size and design. This 6,500mAh case has two kickstands on the back, with each offering three different tilting positions, so you can make sure its angle is just so. A row of LED lights displays the current charge level of the pack, and a USB-C port on the side lets you charge the pack and your Switch at the same time. As a bonus, there’s a storage compartment with enough room to hold two game cartridges, and despite looking like a tank, the Antank only weighs eight ounces.
4. Mthinkor Backup Power Bank for Switch
Best Detachable Nintendo Switch Battery Case
Mthinkor Backup Power Bank for Switch
This snap-on power bank from Mthinkor is less intrusive and more portable than other battery cases, and with 10,000mAh capacity it doesn’t skimp on juice either. Despite its generous capacity, it’s small enough that it isn’t visible from the front when attached to your Switch, so despite some extra weight, you’ll never know it’s there when you’re actually using it.
Easily the coolest feature is the pack can also function as a standard power bank too, so it can give your Switch eight to 12 hours of battery life, and it can charge a smartphone or tablet too via its USB Type-A port.
5. Bionik Power Commuter
Best Nintendo Switch Carrying Case With a Battery

If you don’t like putting a case on your Nintendo Switch or any of your devices, a carrying case might be your best bet. Luckily for you, the Bionik Power Commuter is just that and it includes a 10,000mAh battery pack to save you the trouble of having to buy a carrying case and portable charger separately.
It’s pretty nice as a case on its own as it features a large interior for you to a second set of Joycons, other Nintendo Switch accessories, and your whole game card library with you. Another plus is you can carry this battery case in three different ways with the built-in handle, optional shoulder strap, and flap loop.
6. Anker PowerCore 10000 PD
Best Nintendo Switch Power Bank
Anker PowerCore 10000 PD
Anker is well-known in the power bank world, and its first Switch-approved charger looks pretty awesome. Unlike most stand-alone power banks, the Anker PowerCore 10000 PD lets you charge the Switch while you’re using it, which sets it apart from most power banks, and makes it a lot more useful too.
This charger is good for recharging your Switch 1.7 times, according to Anker, which should equal about 10 hours of playtime total. Plus, if your Switch is topped-off but your phone is on fumes, it also has fast-charge capability for phones as well.
What to Look For in a Switch Battery Case
There are a couple things to keep in mind before pulling the trigger on a battery case for your Switch. First, the original Switch’s internal battery is 4,310mAh and typically lasts about three hours when undocked (depending on the game). The new Switch lasts a bit longer between four to five hours in our experience, though Nintendo has yet to reveal the exact capacity of the larger battery.
Most of the packs I found are around 10,000mAh, so nearly all of them promise to double the life of your Switch, but that won’t always be the case.
There are a lot of factors that go into the efficiency of an external battery pack, so don’t be disappointed if that 10,000mAh battery doesn’t triple your Switch’s battery life. With that said, all of them will still provide quite a boost.
