The LG Gram SuperSlim (2023) is exactly what it sounds like: a slim and lightweight laptop, but with a sleek form factor, the SuperSlim is powerful with its specs. With a 15.6 inch model of the SuperSlim featuring an Intel 13th Gen Core i7 Evo, 32GB of RAM, and a 2TB SSD, there’s no doubt that you’ll be able to use this laptop for nearly any working needs.
Along with being a powerful and easy-to-take-anywhere laptop, the reality is that you’re going to run out of power pretty quickly. The LG Gram SuperSlim (2023) comes with a charger, but I’ve got you covered if you need more charging ports or a different charger for charging your SuperSlim. I’ve selected a few chargers that would work well with charging the LG Gram and may be better than your original charger.
UGREEN 140W 3 Port Charger
The first charger I recommend for charging your LG Gram SuperSlm (2023) is this UGREEN 140W charger. In general, 140W chargers like this one will be reliable for fast charging most USB-C laptops. You can use the total 140W of Power Delivery if you’re charging a single device from USB-C 1, while C-2 can output 100W if you charge one device.
What is more impressive is the charging power you can get when you charge multiple devices simultaneously. For example, you can get 65W of Power Delivery if you charge two devices simultaneously from C-1 and C-2. This makes it possible to charge two LG Gram laptops simultaneously with this charger. Also, if you’re charging three devices simultaneously, the USB-C 1 port outputs 65W, which still lets you charge your LG Gram from C-1 and another two devices via the USB-C 2 and USB-A ports.
This UGREEN 140W charger comes with a USB-C to USB-C cable that is rated to accept 240W of Power Delivery.

Baseus 140W 3 Port Charger
One other 140W wall charger I recommend is the Baseus 140W charger. This Baseus charger is similar to the previous UGREEN charger I recommended; however, the power allocation on this charger is much more intense. Yes, you can get 140W from C-1 and 100W from C-2 if you’re charging just one device at a time; you can also get 60W from the USB-A port when charging alone, while the norm is 22.5W.
The most significant difference between this Baseus 140W charger and others is that when you’re charging multiple devices simultaneously, C-1 drops and maintains a 100W charge rate no matter what. So you can charge your LG Gram SuperSlim (2023) faster even when charging other devices with this Baseus charger; however, know that if you’re charging three devices, the C-2 will output 20W, and the USB-A port will output 18W.
This charger comes with a USB-C to USB-C cable in the box.
| Baseus 140W 3 Port Power Delivery 3.1 Wall Charger Specs | |
|---|---|
| USB-C 1 (Single Port Charging) | 140W |
| USB-C 2 (Single Port Charging) | 100W |

| Size | 3.8 x 3.7 x 1.18 inches |
| Weight | 12.6 ounces |
Oraimo 120W Charging with AC Outlets
If you want to power appliances and charge devices with a charger, this Oraimo 120W charging station doubles as a power strip because it has two AC outlets. There are three USB-C ports and a single USB-A port; the maximum output of the charging section is 120W. So you can charge your SuperSlim (2023) while powering appliances. The max output of the AC outlet section is 1250W, and in my testing, I could power a heater while charging four devices simultaneously.
This charger comes with a USB-C to USB-C cable.

UGREEN Nexode 300W 5 Port Charging Station
This UGREEN Nexode 300W 5 port desktop charger is more of a niche product, meaning that most consumers are not looking to buy this powerful charger with this many ports. This is mainly because the price of this charger is a bit high. This is it if you want the Ultimate Power Delivery USB-C charger. Reviewing and testing this UGREEN charger, I could potentially fast charge three laptops simultaneously. Most chargers on the market cannot do that, so you can charge your LG Gram SuperSlim while charging other devices.
| UGREEN Nexode 300W GaN Fast Charger Specs | |
|---|---|
| USB-C 1 Port (single device charging) | 140W |

UGREEN 145W 25,000mAh Power Bank
If you’re looking to charge your LG Gram no matter where you are, this UGREEN 145W power bank is one of the most powerful portable chargers I’ve reviewed. This charger has a 145W max output; you can use 100W of Powe Delivery from USB-C 1 and 45W of Power Delivery from C-2 at the same time; this makes it possible to charge your LG Gram SuperSlim (2023) while also charging another laptop.
The one other port on this power bank is a USB-A port. Even if you charge three devices simultaneously with this power bank, the USB-C 1 port always outputs 100W. This UGREEN power bank also has a 25,000mAh battery capacity that can charge your SuperSlim to full power and still have spare capacity to use later.
| UGREEN 145W 25,000mAh Power Bank Specs | |

Powdeom 155Wh 150W Mini Station
If you want to use your original LG Gram charger while still being portable, I recommend this Powdeom 150W mini power station. This power station is relatively low-priced and in the range of many higher-capacity power banks, and it has a 150W AC outlet that lets you use your original charger. There is a 60W Power Delivery USB-C port that you can use to charge your LG Gram directly.

Baseus 65W 20,000mAh Power Bank
This Baseus 65W power bank is a popular one on the market that features a 20,000mAh battery capacity and 65W of Power Delivery via its USB-C port if you’re charging one device at a time. There are also two USB-A Quick Charge ports on this Baseus power bank; however, when you charge two devices simultaneously, the USB-C output drops to 45W, and if you charge three devices simultaneously, then the USB-C output drops to 20W.
So, if you want to charge your LG Gram from this Baseus, I recommend charging it alone via the USB-C port. Recharging this Baseus power bank is as fast as the 60W PD recharge rate output.

Baseus 160W Car Charger
The great thing about USB-C chargeable laptops is that you can even use a USB-C car charger to charge your laptop while you drive. Of course, we’re only talking about charging; don’t use your laptop while you drive. This car charger has a 160W max output, and you can use the total 160W if you have the car charger plugged into a strong enough car socket. The C-1 port outputs 100W of Power Delivery, the C-2 outputs 30W, and the USB-A port outputs 30W. This makes it possible to fast charge your LG Gram SuperSlim (2023) via the C-1 port while also being able to fast charge a tablet or phone while you drive. This car charger comes with a USB-C to USB-C cable.
