Best Chargers for Lenovo Flex 5 81X20005US Laptop

Now is the best time to own a laptop, as the improvements made to laptops have been significant in recent years. Modern laptops are a lot faster due to the processors they use, and most notably, most of them now use a Solid State Drive (SSD), which is a lot faster than a Hard Disk Drive (HDD); an SSD ultimately makes laptops faster because it’s able to access data in your computer faster. Most laptops also use more RAM, such as having 16GB of RAM instead of 8GB. However, there are still plenty of brands that offer 8GB of RAM with their laptop at a higher price, and we find that to be unfortunate as 16GB of RAM should be more of the standard.

Since there are still many brands on the market that sell their laptops at inflated prices because of their so-called “Powerful” specs, on the other hand, there’s Lenovo that quietly releases laptops that have great specs and a reasonable price, the specific one that we’re talking about in this case is their Lenovo Flex 5 81X20005US laptop. What makes the Flex 5 laptop powerful is that it features an AMD Ryzen 5 4500U processor, 16GB of DDR4 RAM, and you also get a 256GB NVme SSD that is upgradeable if you want more storage.

Those are all great specs that will make you forget that you’re using a budget laptop, and even the Flex 5 itself is slim and lightweight, making it easy to take anywhere you want. Not exactly pertaining to the performance of modern laptops, but most laptops also feature USB-C ports that you can charge from; this Flex 5 also has a USB-C port that you can use to charge the laptop. If you own the Flex 5 81X20005US laptop, then this guide is definitely for you because we’re covering chargers for the Lenovo Flex 5 laptop.

Aukey Omnia 65W Omnia 65W USB-C Power Delivery Wall Charger

The USB-C Power Delivery charger that comes with the Lenovo Flex 5 laptop is a charging brick type. It’s a 65W PD charger, and it’s great to use for the Flex 5. However, it may prove to be too cumbersome if you’re looking for a laptop charger that you can be more portable with. Thankfully, there are now wall chargers that use GaN, a chip that makes certain PD chargers smaller while still producing lots of charging power.

This Aukey Omnia Dual 65W USB-C Power Delivery wall charger has a minimal length/width of 2 inches only and a thickness of 1 inch. The top USB-C Power Delivery port can output 65W if you’re charging only a single device, and the bottom USB-C port outputs 18W. This charger has dynamic charging, meaning if you’re charging from both ports simultaneously, then the top USB-C port will lower its charging speed to 45W.

You have to use the top USB-C port to charge your Lenovo Flex 5, and a 65W or 45W charge rate will still charge the laptop. Getting into the 30W PD charge rate area is where you’re taking more of a chance with the Flex 5 not charging. That said, being able to charge your laptop and fast charge a smartphone is useful, as most phones are now able to fast charge using Power Delivery, even iPhones, you’ll have to use a USB-C to Lightning cable.

There are two USB-C Power Delivery ports, and each of the ports can output 90W, tons of charging power to charge your Flex 5 at its max chargings speed. The better part of this RAVPower charger is that when you’re charging from both ports simultaneously, then each of the ports can output 45W; this makes it possible to charge two laptops at the same time.

In our tests, we were able to charge a Lenovo Flex 5 laptop and a Microsoft Surface Go tablet simultaneously, with the Flex 5 charging at about 35W and the Surface Go charging at 30W; both of the devices were charging at their max speed simultaneously. The 90W max power output for when you’re charging from a single device is useful if you own a new laptop in the future that can charge faster, so getting this RAVPower charger is a great way to futureproof you’re charging tech.

RAVPower 30,000mAh USB-C Power Delivery Power Bank

One of the best benefits of own a USB-C laptop is that you’re able to charge with a Power Delivery power bank; this way, you don’t always have to carry your wall charger with you and search for an outlet. You’re free to go wherever you want and charge your laptop, and since USB-C chargeable laptops are so common now, there are many options that you can choose from to charge your Flex 5 laptop.

This RAVPower 30,000mAh power bank is one of the best options out there for a PD power bank to charge a USB-C laptop. The power bank has a 30,000mAh power capacity that is enough to charge the laptop to full power about two times if Flex 5 is the only device you’re using to charge with the power bank. Such a high power capacity can also be useful for charging other devices to full power while you’re charging your laptop.

The charging power from this RAVPower power bank is great, with there being a 90W USB-C Power Delivery port, one of the most powerful PD ports on the market with a power bank. There is also a Quick Charge 3.0 USB-A port. If you’re charging two devices simultaneously, then the PD port lowers from 90W to 65W; still tons of charging power to charge the Lenovo Flex 5 at max power.

This power bank can be recharged at 60W via its USB-C port, and we highly recommend that you get a PD wall charger to do so as refilling a 30,000mAh power capacity can take a long time with anything slower. Included in the box is a USB-C to USB-C cable, but not a wall charger.

Excitrus 9,600mAh 45W Power Delivery Mini Power Bank

Power banks with a 30W PD charging speed or higher usually have high power capacity in the 20,000mAh or higher. This Excitrus power bank is the exception to that, as this one has a 9,600mAh power capacity, and yet it has a 45W USB-C Power Delivery port that can charge the Flex 5 laptop. The 9,600mAh power capacity is the main limiting factor as you likely won’t be able to charge a laptop to full power once, but you can at least keep it charged up for an entire day.

The other two ports on this power bank are two USB-A ports, with one that features Quick Charge and the other is a standard port. This power bank also has an LCD that shows how much power capacity you have left.

Of course, there’s the size which is the main reason we’re recommending this power bank and its charging power; this Excitrus power bank has a length of 4 inches, a width of 2 inches, and a thickness of 0.9 inches. You can fit this laptop charging power bank into your pocket easily.

Crave PowerPack 50,000mAh 60W USB-C Power Delivery Power Bank

On the opposite side of the Excitrus power bank mentioned, this Crave PowerPack portable charger has a massive 50,000mAh power capacity. This is one of the best highest capacity power banks on the market that you find that doesn’t have an AC outlet; this is a good thing because using an outlet on this power bank would make it even larger and heavier. With a 50,000mAh power capacity, you’re able to charge your Lenovo Flex 5 laptop to full power about three times; however, with this much power, you can definitely charge other devices to full power at the same time. Basically, you’re looking for many days of use with this Crave portable charger before you have to recharge it.

The charging experience you get is also great because the Crave PowerPack has two USB-C Power Delivery ports and two USB-A Quick Charge 3.0 ports. One USB-C PD port has an 18W charging speed, and the other one has a 60W charge rate. You would, of course, use the 60W PD port to charge your Lenovo Flex 5.

Included in the box is the Crave PowerPack, a USB-C to USB-C cable, and a 45W USB-C PD wall charge that you can use to recharge the power bank at its max speed. You may also use the wall charger to charge your Flex 5 directly.
