The J-Go Tech Tanker is a power bank with an actual name. It arrived charged up. I only needed to top it off for 10 minutes before testing. It’s form factor is like that of Anker and RAVPower 26,800mAh USB-C PD power banks. As is its selection of ports. Unlike those bigger brands, this one support 45W output. Making it better for larger USB-C devices.
Power Meter Readings
Printed Specs vs Manufacture’s Specs
You may note that the power output specs printed on the Tanker and in this review aren’t exactly the same. This review lists the manufacture’s specs. That is the performance the factory (which builds to J-Go Tech’s specifications) advertises. Most power banks list their manufacture specs. J-Go Tech opted for more conservative listings on their device and product listing.
- Manufacture’s Listed USB-C Output: 5V/3A, 9V/3A, 15V/3A, 20V/2.25A
- J-Go Tech’s Listed USB-C Output: 5V/3A, 9V/2A, 15V/2A, 20V/2A
I spoke to J-Go Tech about this. Their approach is to under-promise and over-deliver. They, like most of us, have been disappointed when companies hype up their products to be something that they truly aren’t. They don’t want their customers to experience that with their products.
There is always power loss through inefficiency. A “45W charger” will usually end up being ~42W by the time the power goes into the device. Charger nerds like me know and expect this. But not everyone does, and it can be a surprise for someone using a power meter for the first time. The specs printed on the power bank advertise 40W, so expectations are always met or exceeded.
The good news is my testing shows the manufacture’s specs hold up with the Tanker. It performed in line with other 45W chargers with the Switch and other devices. I opted to base this review on the manufacture’s specs. That is what I tested against. It is also what I use for my other reviews. This provides the best comparison between the Tanker and other power banks.
Pass Through Charging
The Tanker allows for some pass through charging options. Please note this function is not supported or recommended by J-Go Tech. That is normal within the industry. RAVPower power banks support pass through charging, but they also don’t recommend it. The primary reason is excessive use can reduce the lifespan of the power bank.
I was able to get pass through charging with these connections:
- Input: micro-USB, Output: USB-A
- Input: USB-C, Output: USB-A
I was not able to get output through USB-C. The Switch and other USB-C devices may act like they are charging. There is a power connection (normal voltage), but no current (0 amps).
Pass through charging, if done at all, should be the exception rather than the rule. It is useful for charging the power bank and another device from a single USB power source. But the charge is always slower. And it generates more heat for longer, which isn’t good for the batteries. In this case do not use it with the Switch, period.
With or Without USB-C to USB-C Cable
J-Go Tech offers cable flexibility when buying from their website. A USB-C cable is always included if you buy through Amazon. If you buy through J-Go Tech you can get the same deal for the same price. Or you can get the Tanker without a USB-C cable for $6 less. But it is a nice cable for only $6.
The cable itself is 3.3 feet long and nylon braided. If you haven’t had a braided cable before they are very distinct from regular cables. The braided exterior adds structural integrity. They have more texture to the touch, compared to smooth plastic of regular cables. Nylon braided cables have better durability and can take more abuse. But they are less flexible, thicker, and heavier. You can still wrap it up, and a velcro cable tie is included.
The J-Go Tech Tanker lives up to it’s unique name. With 26,800mAh capacity it’ll recharge the Switch more than 3 times. That is more than 12 hours of playtime with an already charged Switch, even with the most demanding games. Unlike most other 26,800mAh power banks it outputs up to 45W.
The Switch doesn’t need 45W output for handheld charging. A 30W power bank will do the same for the Switch on the go. Where 45W shines is with larger USB-C devices. It better supports laptops. It’ll charge up to 13-inch laptops under most conditions. And it’ll work well with 15-inch laptops, provided they aren’t under heavy load. And unlike 30W models it’ll power the Nintendo Switch dock, though that isn’t a common need.
Pass through charging isn’t officially supported, but works under some conditions. You can output via USB-A with either input port charging. But you can’t output via USB-C. If you try (don’t) the Switch indicates a charge, but no current is being draw. The included USB-C cable is ~3.2 feet long and braided. The braiding makes it stronger and more durable. It’ll still wrap up with the included velcro cable tie.
This power bank falls within the FAA’s limits for flights within the United States (100Wh vs the Tanker’s 99.1Wh). If traveling outside of the U.S. contact any airlines you will be flying with. Check the limits for lithium batteries, which are usually based on the country of origin. Most airlines post these limits on their websites.
J-Go Tech is located in southern New Jersey, USA. Support is available via phone and email. They offer a 30 day satisfaction guarantee and a 24 month warranty.
The J-Go Tech Tanker is an affordable large capacity, high output power bank. Well suited for travel with a Nintendo Switch, phone, and USB-C laptop.
