The Lenovo Slim Pro 9i is an absolute laptop workhorse for those looking to do general work and media usage; if you’re a creative professional and work on video or photo editing, it can keep up. The Slim Pro 9i from Lenovo is also great for gaming. This is all thanks to the laptop using NVIDIA GeForce RTX 40 Series GPU.
The Slim Pro 9i has two versions: a 14-inch and 16-inch model. The good news is that you can charge the 14-inch model via USB-C, but the 16-inch model requires that you use a 170W particular type of charger. If you’re looking for a replacement charger or want an upgrade for your Slim Pro 9i 14-inch model, that’s what I’m covering in this guide.
Baseus 140W 3 Port Charger
The charger that I want to recommend that would work well for charging your Slim Pro 9i 14-inch model is this Baseus 140W charger. 140W chargers, in general, are the way to go if you want to fast charge your laptop and charge other devices simultaneously. This Baseus 140W charger has two USB-C ports and a single USB-A port, but what makes this one different is the power allocation when you charge multiple devices simultaneously.
Yes, you can use 140W of Power Delivery if you charge one device via the USB-C 1 port; however, if you charge three devices simultaneously, the C-1 port can output 100W. So you can fast charge your Slm Pro 9i from the C-1 port while charging another two devices via the C-2 and USB-A ports. That said, when charging three devices, the C-2 port outputs 20W, and the USB-A port outputs 18W, making them most suitable for charging tablets or phones at that point.
This Baseus 140W charger does come with a USB-C to USB-C cable.

ThinkPad Mobile Workstation Slim 170W Charger
So, if you’re searching for a replacement charger for your Lenovo Slim Pro 9i 16-inch model, your best bet is to go within the 170W original charger, as the laptop requires that you use this specific charger to charge it. That said, if you want a portable way to use this 170W charger, then I recommend that you use something like an EcoFlow River 2 power station that lets you plug in the Lenovo 170W charger into the power station and use the 170W charger in a portable manner. It’s not ideal, but it gets done if we talk about being portable and wanting to charge your Slim Pro 9i 16-inch model laptop.
UGREEN 140W 3 Port Charger
Another 140W charger I want to recommend is this UGREEN 140W charger; this one also comes from a trusted brand in the charging market. So you can use the total 140W of Power Delivery via C-1 or 100W from C-2 if you charge one device at a time for this charger.
The main difference is that when you’re charging three devices simultaneously, C-1 outputs 65W, and C-2 outputs 45W when charging three devices simultaneously with this UGREEN charger. When charging three devices, you get less power via the C-1 port; however, 65W of Power Delivery is still enough to charge your Slim Pro 9i 14-inch model.
Also, this UGREEN charger can output 65W of Power Delivery from C-1 and C-2 if you’re charging two devices simultaneously. This makes it possible to charge two Lenovo Slim Pro 9i laptops simultaneously—this UGREEN charger comes with a USB-C to USB-C cable in the box.

VOLTME 140W 3 Port Charger
One other 140W charger I want to recommend is the VOLTME 140W charger. This one comes from a smaller brand, so the price can sometimes be lower. That said, charging power works like the UGREEN charger I mentioned earlier. This VOLTME charger can also output 140W of Power Delivery if you charge via the C-1 port alone. The C-1 port can output 65W if you charge three devices at once.
Also, the dual USB-C charging still results in a 65W output via the two ports. The only thing missing with this VOLTME Charger is that it doesn’t have a USB-C to USB-C cable.

UGREEN Nexode 300W 5 Port Charging Station
The UGREEN Nexode 300W charging station is as extreme as it sounds because this charger has a 300W max output and five charging ports. There are four USB-C ports and a single USB-A port on this charger; along with the 300W max output, you could easily charge your Slim Pro 9i 14-inch model, another two laptops, and a phone or tablet simultaneously. According to the power allocation in my review testing, charging multiple laptops is possible.
This charger is a bit pricy, but it will be the only charger you will need for a long time. You do get a USB-C to USB-C cable in the box.

UGREEN 145W 25,000mAh Power Bank
The great thing about USB-C chargeable laptops is that you can use a USB-C power bank and charge your laptop anywhere. This UGREEN 145W power bank is one of the most powerful PD power banks that I have reviewed, with the charger having a max output of 145W; the C-1 port can output 100W of Power Delivery, and the C-2 port can output 45W of Power Delivery at the same time. With the dual charging power allocation, you can charge your Slim Pro 9i while charging another laptop. Even if you’re charging three devices simultaneously with this power bank, the C-1 port continues to output 100W, and the 25,000mAh battery capacity can charge the Slim Pro 9i to full power about once.
