For a nomad like me, you can never have enough power. It sounds weird, I know, but when you don't have access to a house, you have to be creative. I recently received the Bluetti AC50B for testing here in Canada, and I was curious to see if this product is suitable for multi-day adventures.
I've been testing the Bluetti AC50B for about a week and a half, and while at face value it might just seem like any old generator, there are a few differences that make it better for outdoor folks like me.
This first impressions article is just that—my initial thoughts on this device regarding construction, versatility, and power generation. You'll learn whether or not this is a product that you should consider for your next trips
Meet the Bluetti AC50B
In my opinion, the Bluetti AC50B strikes a balance between portability and power. Weighing in at just 15 pounds, it's a breeze to carry compared to other models. It has a single handle built into the top, much like their other recent models. I like this handle design as it feels sturdy when carrying; I don't have the feeling that the handle will suddenly break and fall off.
They introduced some rubberized buttons with this unit, and it makes a significant difference. There is a feeling of substantiality when pushing the buttons. They are of a more rugged construction, which I can see helping to prevent debris from getting into the buttons.
The other notable difference is the slight reconfiguration of DC output ports. There are two USB Type-C ports and one USB Type-A port. With the output power capabilities of USB-C and how most of my devices now use this charger, having two of these available is awesome. They have switched to this configuration for many of their newer models.
Positioned between the AC2A and the AC70 models, the AC50B offers a sweet spot for those who need reliable power without the bulk. I found the AC2A quite small for multi-day charging (for multiple people), but the AC50B seems to help with that quite a bit. I've been charging my laptop and phone batteries for a few days now, and it's still above 25%.
I'll be sharing a more in-depth review after 45 days of use, but for now, let's explore its features and performance.
Product Overview
In my experience, when you're out in nature, you need to be resourceful, even with your electronics. With 700W continuous power and a 448Wh battery capacity, it can handle charging multiple laptops (while they're turned off), cameras, and cell phones for up to 3 days.
If you need a boost of power there is 1000w lifting power. For example, if you need to power something like a portable waffle maker (Yes, I tried it).
The variety of ports—2 USB Type-C ports, 1 USB Type-A port, 2 AC outlets, and 1 cigarette lighter port—means I can charge all my gadgets.
One of my favourite aspects of this unit is that I can plug it into the wall to charge at a library or something and within 45 minutes I am charged up to almost 90%. This is convenient for people like me who don't want to be waiting inside to charge my battery.
I haven't had the chance to charge it using the 120W solar panel. But if it's anything similar to the other devices I would say it will be charged within 5 hours of full sunlight.
Intended User Experience
I've compiled a few scenarios that I think the AC50B will excel in, based on real-world experience and what my brain extrapolates based on this current performance.
For the Outdoor Enthusiast
These are the folks who have their cameras, cell phones, headlamps, and GPS units to worry about. This unit will have ample power to charge these devices multiple times over a few days. While it isn't technically 'lightweight,' it is still lighter than other units, and if you aren't going too far back into the woods, it's still a great unit to have.
On the Road as a Digital Nomad
Digital nomads are those who work while they travel and often need this kind of portable power solution. They frequently have laptops to charge (and use while charging), cell phones, Bluetooth headphones, and other small electronics. It might not seem like a lot, but the caveat here is that these devices are often charging while they are being used.
With that in mind, this unit can power all of these things for at least 6 hours of continuous use (depending on the wattage being pulled). You might think that isn't a long time, but considering you can charge it almost fully in 45 minutes, it becomes a viable option.
A Lifeline for Emergency Preppers
If you're considering using this instead of a larger, dedicated power station or a gas generator, then think again. There is simply not enough capacity to power an off-grid homestead or any heavy tools for any length of time.
Where this unit fits into this category as a small backup power station that you use for your electronic devices when the power goes out or you go into the woods for a few days. Don't get this unit if you are intending it for heavy electricity usage.
Benefits and Drawbacks
Here are some of my observations based on the short time I've been using this unit. Spoiler alert, there aren't any cons, just observations that I'll make to help improve the product.
Advantages of the Bluetti AC50B
Compact and weighs only 15lbs
Rubberized buttons provide a premium feel
2 USB-C ports provide quick charging for appropriate devices
1 hour charge time with Turbo Mode is pretty nifty
The updated Bluetti app works well with this unit
Speaking of the Bluetti App - don't forget to download it. Not only for the ability to control it remotely but for the BMS and various software updates they may release for performance reasons. If there are any potential problems with the unit they can push out an update to help resolve it.
Areas for Improvement
While the AC50B offers impressive features, there's always room for enhancement. Here are some of the ways I think this unit could be improved even more.
Colour-changing LEDs on the rubberized buttons could help customize the experience. For example, red lights would be easier on the eyes if you were using the unit at night
Illuminating the various ports (or even the text underneath) so that you can find the entry points without having to turn on a light at night. Instead of just feeling around and trying to make sure the cable goes in.
Somehow integrating a shoulder strap onto the unit so that you're not stuck carrying it by the handle.
As you can tell, these are minor gripes and the unit itself works very well. Bluetti seems to improve the design with each iteration so hopefully they integrate some of this advice into their next units.
Closing Thoughts
In my short time with the Bluetti AC50B, it's already proven to be a versatile and dependable power solution for my various needs. Its value lies in its small form factor when it's charging the right devices. Don't go into this expecting it to power your heating gun or something, it's meant to be used for small electronics.
As I said before, I will provide an updated review after 45 days of using it. For what it's worth right now, however, the AC50B is a good buy from my perspective.
