Lenovo GO USB-C Laptop Power Bank Review
I rely on a power bank every day, and only the most powerful options can keep up with the demands of laptop charging or topping up portable gaming devices.
While there are plenty of great options in our guide to the best power banks, most don’t have built-in cables, so you’ll need to carry a few extras when you’re on the go.
And that’s where Lenovo goes in the slot, with 65W output and a built-in cable that hides in the power bank itself, so it’s ready to go whenever needed.
Aside from the cable, it also has both USB-C and USB-A ports and can receive three devices simultaneously.
The Lenovo Go has a typical 20,000 mAh, 74WH (although the unit itself says 77WH) capacity, which makes it ready to take flights without authorization, and is capable of topping up a laptop at least once or charging your phone for several days. The steam in the deck is also enough to give a full charge to the 50WH battery.
At 170 × 72 × 23 mm (6.69 × 2.83 × 0.91 in), it’s reasonably compact, and the 390 g (0.86 lb) weight is quite modest considering the capacity. The design is slim enough to slip into any bag (including a briefcase-style laptop bag) without adding bulk.
The built-in USB-C cable is 44 cm (17.3 inches) long and wraps around a recess in the power bank for storage. Safe and easy to deploy, it’s super lightweight to put away in a clean place once you’re done charging.
The USB-C end is a bit too big, so it may not fit into some USB-C ports with tighter access, like phones with thicker cases.

The power bank uses a simple four-led system to display remaining capacity in 25% steps, which works fine but isn’t as good as a digital readout. The plastic shell feels solid in the hand and is quite tough, and despite being tossed around in my bag for a few weeks, it showed no signs of undue wear.
The Lenovo Power Bank faces stiff competition from similar spec power banks, such as the slightly cheaper Anker 20,000mAh 87W Power Bank. The Lenovo is slightly thinner (but taller) and lighter, but to give it comparable value for money, it needs to be picked up when it’s on sale.

Lenovo Go USB-C Laptop Power Bank Output USB-C cable and USB-C port-5V 3A, 9V 3A, 15V 3A and 20V 3.25A USB PD3.0 specific voltages. This means it will happily charge most phones, laptops and other devices such as handheld gaming machines at up to 65W. USB-A port supports QC3.0 protocol, variable from 5V, 9V, 12V or 3.6V to 12V, up to 18W.
In particular, it doesn’t support PPS (Programmable Power Supply), so it won’t do 45W Samsung Super Fast Charging like the INIU P50 can.
The Lenovo Power Bank also doesn’t output 12V on the USB-C ports, which shouldn’t be a problem for most users, but it’s still notable. There aren’t many devices that specifically require 12V USB-C charging, but, for example, the DJI mini drone batteries require a 12V option for fast charging.
So even though Lenovo doesn’t have the latest protocol support, it’s not capable of fast charging any of your devices for normal use.
Lenovo Go USB Laptop Power Bank: Price and Specs
You can buy Lenovo Power Bank directly from Lenovo or various other marketplaces and retailers.
list price. It’s 140.99 / £84 / au$138, but it often goes on sale for much less during sales events, so it’s worth waiting for a discount if you don’t need it right away.
The power bank has a standard warranty of 1 year, and we’re a little disappointed that Lenovo didn’t offer at least 2 years.

Lenovo GO USB-C Laptop Power Bank: Test Results
Many power banks make bold claims, but in real-world testing they don’t live up to the hype. So to eliminate duds, I do comprehensive testing to verify charge voltage, protocol support and login capability tests.
Overall, the Lenovo Power Bank delivers solid results considering it’s thinner and lighter than many similar spec options and has a built-in cable.
Test | Usable capacity | performance | Score |
|---|---|---|---|
65W laptop charging | 61.5 wh | 83.1% | 3.5 / 5 |
30W laptop charging | 62.5 WH | 84.4% | 3.5 / 5 |
20W phone charging | 65.3 WH | 88.2% | 4/5 |
10W charging | 68.1 WH | 92% | 4.5 / 5 |
For 65W laptop charging, the Lenovo Go 61.5WH rates 74WH available, with a typical 83.1% efficiency rating. Lenovo only rates the power bank at 48WH while outputting 65W (20V 3.25A), so the real-world test results of 61.5WH are much better.
I will note, though, that after about 45% capacity remains, it re-negotiates a slower charge rate to protect the battery cells. This is fairly common, and when tested on a laptop that’s being used the low average power draw doesn’t trigger this mode.
At an average 30W output when running the laptop, performance is slightly better, at 84.4%.
For charging the phone at 20W, the Lenovo Power Bank hit a great efficiency of 88.2%, and if charged slowly at 10W, it can output 92% of the rated capacity.
The power bank is rated for 74WH by Lenovo Online, but the actual power bank notes 77WH. This is a slight oversupply of capacity by Lenovo, which is a good thing, and I used the 74WH rating for the above performance calculations.
When pushed hard with constant maximum output until empty (such as when charging a laptop), the Lenovo Power Bank reached a hearty but barely 42°C (108°F), while phone charging only reached 28°C (82°F). While it’s usually best to charge a laptop at a desk, the Lenovo Power Bank stays cool enough that I wouldn’t mind using it in a bag.
The power bank can charge up to 100W via the built-in cable or USB-C port and the backup takes about 1.5 hours.

How do I test power banks?
I test and extensively evaluate each power bank in both lab and real-world scenarios. Using tools like the ChargerLab Power-Z KM003C, I measure charge voltage, check protocol support, and log capability tests.
Each power bank is also tested with everyday devices, including phones, tablets and laptops, and connected to a programmable load tester for multiple charge cycles. I do a daily selection of both pockets and bags to gauge their durability and ability to withstand everyday use.
All measurements and weights are personally verified, ensuring accuracy beyond the manufacturer’s listing. It’s worth noting that many power bank reviews don’t carry out such tests, so they should be taken with a grain of salt.
