The Bluetti Elite 100 V2 is the current model and the direct replacement for the now-discontinued Bluetti AC180. It wins on almost every line that matters: it’s 5.5kg lighter (11.5kg versus 17kg), takes double the solar (1,000W versus 500W), has a bigger 3,600W surge, a faster 10ms UPS, more battery cycles, a 140W USB-C port and a 5-year UK warranty. The AC180’s one edge is capacity, at 1,152Wh against 1,024Wh, roughly 11% more. For anyone buying new, the Elite 100 V2 is the pick. The AC180 only makes sense if you already own one, or you find a cheap used unit and want that bit of extra capacity.
Who Should Choose Each?
Choose the Bluetti Elite 100 V2 if:
- You’re buying new. It’s the current model and the AC180’s direct replacement.
- You want the lighter unit, at 11.5kg against 17kg, a 5.5kg saving.
- Solar matters. Its 1,000W input is double the AC180’s 500W.
- You want the faster 10ms UPS, the bigger surge, the quieter running and the longer 5-year warranty.
Best for: solar off-grid, camping, and home backup.
Choose the Bluetti AC180 if:
- You already own one and it still works well for you.
- You find one cheap on the used market and don’t mind buying secondhand.
- You specifically want the slightly larger 1,152Wh capacity, roughly 11% more.
- You accept the trade-offs: heavier, less solar, a slower UPS and no current warranty on used units.
Best for: existing owners and used-market buyers wanting a little more capacity.
Solar Charging in the UK
Which takes more solar, the Elite 100 V2 or the AC180?
The Elite 100 V2 takes far more, at 1,000W of solar input against the AC180’s 500W, exactly double. On a bright UK summer day a 1,000W array can refill the Elite 100 V2 in around an hour to an hour and a half, while the AC180’s 500W cap takes a good deal longer from the same conditions. For solar-first use, the newer unit is the clear winner.
The gap counts most for off-grid living. In a motorhome with roof panels or a static setup, the Elite 100 V2’s higher ceiling means you capture much more during the short window of good UK light. Our UK solar charging guide sets realistic expectations, and our best solar generators for the UK covers more solar-first options.
The Elite 100 V2 wins decisively, at 1,000W against 500W. Double the input is a fundamental off-grid advantage, and it’s the single biggest reason to pick the newer unit.
Weight and Portability
Which is easier to carry, the Elite 100 V2 or the AC180?
This is where the redesign shows most. The Elite 100 V2 weighs 11.5kg, while the AC180 is 17kg, a difference of 5.5kg. That’s a big saving to lift into a car boot, carry across a campsite, or shift around a caravan. The Elite 100 V2 is also about 35% smaller, so it takes up less space too.
For anyone who moves the unit often, the lighter body makes a real day-to-day difference. The AC180 is still a one-person carry, but it’s a heavier, bulkier one. If portability is on your list, the Elite 100 V2 is the more comfortable choice for camping and campervan use.
The Elite 100 V2 wins clearly. At 11.5kg it’s 5.5kg lighter and around 35% smaller than the 17kg AC180, a genuine upgrade for anyone carrying it regularly.
Surge and Power
Which handles more demanding appliances?
On continuous output the two are level: both deliver 1,800W, and both use Power Lifting to drive heating appliances up to 2,700W via the app. So for a lower-rated kettle, a fan heater or a hairdryer, they behave much the same. Neither runs a full 3,000W kitchen kettle without Power Lifting.
The difference is surge. The Elite 100 V2 has a 3,600W surge against the AC180’s 2,700W, which gives more headroom for start-up spikes from fridge compressors, pumps and power tools. If your gear has a heavy kick when it switches on, the newer unit copes with it more comfortably.
A tie on continuous output at 1,800W, and both share Power Lifting to 2,700W. The Elite 100 V2 wins on surge, at 3,600W against 2,700W, for easier appliance start-up.
Charging Speed
Which charges faster from the mains?
To 80% they’re identical: both reach 80% in about 45 minutes, so existing AC180 owners won’t notice any change in their everyday charging routine. The gap shows on a full charge. The Elite 100 V2 tops up completely in around 70 minutes, while the AC180 takes about 90 minutes.
The reason is that the Elite 100 V2 holds a higher input rate later in the charge rather than tapering off as early. In practice you’ll feel the difference only when you need a full battery quickly. Both also accept mains and solar at the same time to shorten the top-up further.
A tie to 80% at 45 minutes. The Elite 100 V2 edges the full charge, at around 70 minutes against the AC180’s 90, thanks to a steadier input rate.
Home Backup and UPS
Which is better for power-cut protection in the UK?
Both units offer a UPS, so either will keep kit running through a power cut. The difference is switchover speed. The Elite 100 V2 flips to battery in 10 milliseconds, three times faster than the AC180’s 30 milliseconds. Both are quick enough that a router, NAS drive or desktop stays on when the mains drops, but the newer unit has more margin.
Neither can be expanded, so each gives a fixed buffer: 1,024Wh on the Elite 100 V2 and 1,152Wh on the AC180. Around 1kWh keeps a fridge, router and a few devices going for several hours, not days. Our home backup buying guide walks through how to size for your own setup, and our sizing calculator gives you a quick runtime estimate.
Both have a UPS, so neither leaves you exposed. The Elite 100 V2 switches three times faster, at 10ms against 30ms; the AC180’s slightly larger battery gives marginally longer runtime.
Battery Life, Warranty and Capacity
Which lasts longer, and where does the AC180 fight back?
On longevity and cover, the Elite 100 V2 leads. It’s rated for 4,000+ charge cycles to 80% capacity against the AC180’s 3,500, and it carries a 5-year UK warranty against the AC180’s 3 years. Both use LiFePO4 cells, so both are safe, stable chemistries built to last many years of regular use.
Here’s the AC180’s one genuine advantage: capacity. At 1,152Wh it holds roughly 11% more than the Elite 100 V2’s 1,024Wh, which works out to about 30 to 40 minutes more fridge runtime from a full charge. For most people that’s a small gap, and the Elite 100 V2’s weight saving and extra solar more than make up for it. But if you regularly pushed an AC180 to its limits, it’s worth noting.
One caveat on warranty: a used AC180 won’t come with current cover, so the 3-year term only applies to units still within an original registration. For a fuller picture of where both sit, see our best portable power stations guide.
The Elite 100 V2 wins on cycles (4,000+ against 3,500) and warranty (5 years against 3). The AC180’s only comeback is capacity, at 1,152Wh against 1,024Wh, its single real edge.

The newer unit is 5.5kg lighter, takes double the solar, switches over three times faster as a UPS, has a bigger surge, a quieter fan, a faster USB-C port and a longer warranty. They match on output and Power Lifting, and on charge to 80%. The AC180 leads on one line only: capacity.
When the Bluetti Elite 100 V2 is the better buy
Choose the Elite 100 V2 for essentially every new purchase. It’s the pick if solar is central to your plans, if you want the lighter unit to carry, if you value the faster UPS for home backup, or if the 5-year warranty and current support matter to you. For solar off-grid, camping and power-cut cover, it’s the stronger unit across the board.
When the Bluetti AC180 is the better buy
Choose the AC180 only in narrow cases: you already own one and it’s serving you well, or you find one cheap on the used market and specifically want the extra 1,152Wh of capacity. Just accept the trade-offs of a heavier body, less solar, a slower UPS and no current warranty on a secondhand unit.
Buying new: the Bluetti Elite 100 V2, without hesitation. The AC180 is only worth it if you already own one or find a cheap used unit and want the slightly larger battery. For the wider market, see our best portable power stations guide.
