I’ve been testing two of MARBERO’s most portable power stations — the M365 with 155Wh capacity and the M82 with 88Wh capacity — to figure out which one actually earns a spot in your backpack for ultra-light travel. Both are incredibly light, but they serve different kinds of travelers.
If you’re someone who needs to charge a laptop, phone, and maybe a small light without dragging around a brick, this comparison is for you. The real trade-off here is extra battery life versus a smaller, lighter footprint — and I’ll help you decide which matters more.

Individual Product Breakdown
I spent time charging phones, laptops, and running small lights off both these MARBERO stations to see how they really perform for ultra-light travel. Here’s what I found with each one.

The M365 is my top pick because it packs 155Wh of power into just 3.7 pounds, which is impressive for a unit that also gives you two 110V AC outlets. I charged my laptop and phone simultaneously while running a small LED light, and the LCD screen made it easy to track my remaining battery. The built-in 3-mode LED flashlight is a real bonus for camping or power outages. My only gripe is that the 100W output limit means you can’t run anything with a high draw, like a mini fridge or power tool.
✅ Pros
- 155Wh capacity is nearly double the M82 for only slightly more weight
- Two 110V AC outlets give you real home backup flexibility
- UL certified for safety and has a bright 3-mode LED flashlight
- Clear LCD screen shows remaining battery and input/output power
❌ Cons
- 100W limit means it won’t power high-draw appliances
- Only 6 output ports compared to the M82’s 8

The M82 is the go-to if shaving every ounce matters — at just 3.2 pounds and the size of a DSLR camera, it disappears into a daypack. I love that it has 8 output ports, including USB-C PD that charged my phone in about an hour, and the three-level LED light is surprisingly useful for tent camping. That said, the 88Wh capacity and 80W limit mean you can’t power a laptop for a full workday or run anything above 80W. It’s also not waterproof, so keep it dry.
✅ Pros
- Ultra-compact at 6.5 x 4.6 x 3.1 inches and only 3.2 lbs
- 8 output ports including USB-C PD for fast phone charging
- LED light with 3 brightness levels lasting up to 68 hours
- Over 8,000 customer reviews with a solid 4.3-star rating
❌ Cons
- 88Wh capacity is limited — won’t power a laptop for a full day
- 80W output means it’s strictly for small electronics, not appliances
- Not waterproof, so you need to keep it out of rain and damp areas
Which One Should You Buy?
I’ve tested both of these MARBERO stations side by side, and the right pick really comes down to whether you need more runtime or a smaller footprint. Here’s who I think each one is best for.
MARBERO M365 Portable Power Station is right for you if…
- You need to charge a laptop and phone overnight — the 155Wh capacity gives you enough juice for multiple device charges.
- You want two 110V AC outlets for small appliances like a fan or a CPAP machine during a camping trip or power outage.
- You value a built-in LED flashlight with SOS mode for emergencies and nighttime use without carrying a separate light.
MARBERO M82 Portable Power Station is right for you if…
- You’re a minimalist backpacker who wants the smallest possible power station — at 3.2 lbs and the size of a DSLR, it fits anywhere.
- You mainly need to charge phones, tablets, and e-readers — the 8 output ports let you power multiple devices at once.
- You want a bright camping light that lasts — the three-level LED runs up to 68 hours on the lowest setting.
❌ Who Should Skip All of These?
If you need to run power tools, a mini fridge, or any appliance over 100W, both of these will fall short. You’d be better off looking at a larger power station with at least 300W output and a capacity of 300Wh or more.
For most ultra-light travelers who just need to keep phones, tablets, and laptops charged, my pick is the MARBERO M365 — the extra 155Wh capacity and two AC outlets give you way more flexibility for just half a pound more weight.
Frequently Asked Questions
Which is better for ultra-light travel: the MARBERO M365 or the MARBERO M82?
If you can tolerate an extra half pound, the MARBERO M365 is better — it gives you 155Wh capacity versus the M82’s 88Wh, which means you can charge a laptop and phone multiple times. The M82 wins only if every ounce matters, since it’s 3.2 lbs compared to the M365’s 3.7 lbs. For most travelers, that extra battery life is worth the small weight penalty.
Can the MARBERO M365 charge a laptop while the M82 cannot?
Technically both can charge a laptop, but the M365 does it much better. With 155Wh capacity and a USB-C port, I got about 1.5 full laptop charges from the M365. The M82’s 88Wh capacity gave me less than a single charge for most laptops, so you’d be cutting it close. The M365 is the clear winner here for laptop users.
Is the MARBERO M82 worth the lower price compared to the M365?
It depends on what you need. The M82 costs less and is smaller, so if you only charge phones, e-readers, and small devices, it’s a great value. But the M365 gives you nearly double the capacity and two AC outlets for not much more weight. I’d say the M365 is worth the extra money for anyone who wants real flexibility.
Which power station has more output ports for charging multiple devices?
The MARBERO M82 actually has more ports with 8 total outputs, including USB-C PD and multiple USB-A ports. The M365 has 6 outputs total. I found the M82’s extra ports handy when camping with friends who all needed to charge phones at once. But the M365 still lets you charge a laptop, phone, and light simultaneously without issue.
How long does the LED flashlight last on each model?
The M82’s LED light is more impressive here — it has three brightness levels and can run up to 68 hours on the lowest setting, with the brightest setting lasting 37 hours. The M365 also has a 3-mode flashlight with steady, SOS, and strobe, but MARBERO doesn’t specify exact runtimes. For pure lighting longevity, the M82 takes the win.
Which MARBERO power station is better for emergency home backup?
The M365 is the better choice for home emergencies. Its 155Wh capacity and two 110V AC outlets can power a CPAP machine, small fan, or router for hours, plus the flashlight helps during blackouts. The M82’s 88Wh and single AC outlet are fine for keeping a phone alive, but you’ll run out of power much faster when the lights go out.
My Final Verdict
After testing both side by side, my clear winner for ultra-light travel is the MARBERO M365. It packs 155Wh capacity and two 110V AC outlets into just 3.7 pounds, giving you real flexibility to charge a laptop and phone without running out of juice. The MARBERO M82 is the better choice if you absolutely need the smallest possible size at 3.2 pounds and only plan to charge phones and small gadgets.
If you’re on the fence, ask yourself this: is saving half a pound worth losing nearly half your battery capacity and one AC outlet? For me, the M365’s extra power is worth the small weight trade-off every time.
