First Impression

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 has the same basic design of Anker and RAVPower’s 26,800mAh power banks. But unlike those it offers 45W output, enough for most small and mid-sized laptops. Mine came with a couple of cables and long pouch. If you buy from Amazon it’ll be the same. If you buy from J-Go Tech directly you can pick and choose from several accessories at various prices.

The Nintendo Switch charges at its max rate, charging while you play. Its charge rate while sleeping is also normal. This charger can also power the Switch’s dock. Learn more about charging the Switch.

The PD protocol negotiation with the Switch is typical. It connects at 5V and moved up to 15V after negotiations. Current steps up once the 15V connection is made.

The iPhone 8 fast charges when using a USB-C to Lightning cable. We see the usual power negotiations. Connection starts at 5V, then moves up to 9V. Learn more about fast charging iPhones.

The Moto G6 charges slower than expected via USB-C. It is ~8W instead of the usual 10W. This may or may not also be the case with Samsung and Quick Charge enabled Android phones. The Google Pixel and Android phones that support USB Power Delivery will fast charge on the USB-C port. Learn more about fast charging various Android phones.

As a 45W charger it can support 12-inch laptops. As well as 13-inch models running office, Internet, and entertainment apps. If playing video games or using CPU intense apps it may only extend battery life. But either way you get a lot more uptime. Learn more about charging USB-C laptops.

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.

  • Printed USB-C Output: 5V/3A, 9V/2A, 15V/2A, 20V/2A
  • Actual USB-C Output: 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/2.25A

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.

Using the Included USB-C to micro-USB Adapter

As a general rule it is safe to use a USB-C to micro-USB adapter. Such as the one J-Go Tech included. It is an adapter that connects to a micro-USB cable, giving it a USB-C end. It is not safe to use the opposite, turning a USB-C connection into any kind of other connection. That would allow for connections against USB standards, and dangerous to devices. Again, the adapter J-Go Tech included is the good kind.

My USB tester showed the micro-USB cable with USB-C adapter has a 56k Ohm resistor. That resistor is required under USB-IF rules for all USB-C to USB-A connecting cables.

The cable fast charged my Moto G6 at the same rate as a regular USB-C to USB-A cable. Both allowed the Moto G6 to draw 16W from the USB-A Quick Charge port.

Pass Through Charging

Pass through charging allows a power bank to both recharge and charge a connected device. Some of the energy flows from the wall output, through the power bank, to the device. The remaining energy recharges the power bank itself.

The Tanker supports pass through charging:

  • Input: USB-C, Output: USB-A
  • Input: micro-USB, Output: USB-A

You can use either USB-A port to charge while the power bank re-charges. I was not able to get output through USB-C. If you try your USB-C devices may act like they are charging. There is a power connection (normal voltage), but no current (0 amps). To the device indicator shows a charge but the battery will continue to drain.

Pass through charging is useful for overnight stays with limited wall chargers. It is not recommended to do so on a regular basis. It puts more heat and stress on the power bank, which can affect its lifespan. Doing it when traveling is fine. But don’t set this up next to your bed at home every night.


The J-Go Tech Tanker lives up to its name. With 26,800mAh capacity it’ll recharge a laptop more than once, a Switch more than three times. And it is among the few large power banks to offer 45W output and almost as fast of a recharge for itself.

For the Nintendo Switch it charges in handheld mode as fast as any other option. And it can power the Switch when docked, should the need arise.

Its 45W USB-C output works well for small to medium sized USB-C devices. Especially phones and tablets that support USB Power Delivery, and up to 13-inch laptops.

The lack of Quick Charge is its only output issue. Most Android phones use Quick Charge or a fast charging standard that mimics it. Samsung, Motorola, and Quick Charge enabled phones will charge at a normal rate using USB-C to USB-A. But no fast charging.

Pass through charging isn’t officially supported by J-Go Tech, but works nonetheless. You can charge via the USB-A ports while recharging. It won’t output via USB-C. It you try your device may show it is charging, but no current is actually being drawn.

The Tanker falls within the FAA’s limits for flights within the United States, barely. The limit is 100Wh, the Tanker is 99.1Wh. If traveling outside of the U.S. contact your airline before you leave. Check the limits for lithium batteries, which are based on the country of origin. Most airlines post these limits on their websites.

Bottom Line

The J-Go Tech Tanker is a great value high output, large capacity power bank. With a handheld Switch you can get by as well with a 30W power bank. But if you have a laptop this will serve both better. Its competitors offer lower output, less capacity, or a higher price. While the power bank is made in China the company is based in the U.S.
