How this score is calculated

Scores calculated by comparing verified specifications across our catalogue. No hands-on testing. Comparison of documented models, not an exhaustive market survey. n is the number of models compared for each criterion. No hands-on testing.

The score is the average of individual scores, each based on a verifiable criterion for the category. The same scoring system applies to all models, using available, verified specifications.

Rated power	8.8/10: 2400 w, ahead of 69% of the models in the catalogue · n = 32
Battery capacity	8.4/10: 1462 wh, ahead of 58% of the models in the catalogue · n = 31
Equipment	6.6/10: 1 of 13 tracked features documented, ahead of 0% of the models in the catalogue · n = 33

When data is missing for a model, we don't make assumptions or penalise it: that criterion isexcluded from its score. We analyse specifications and aggregated feedback, we do not carry out hands-on product testing. Affiliate links never influence the score.

Our scores explained

Every model on the site is scored on the same criteria, using the same scale: its position among models with verified data for that specification. Last place earns 6.5, first place 9.6, and the rest are scored in proportion to their rank. Here is how this model's scores are calculated.

Two model counts: the rank and average include product pages on this site scored for the criterion; the calculation compares the model with all catalogue models whose specification is verified, with or without a product page. A score assigned at publication may remain without a verified specification, so the first count can sometimes be higher.

Rated power: 8.8/10

Ampace Andes 1500 scores 8.8/10 on this criterion. Across the 27 product pages on the site with a score for this criterion, the average is 8.1: above average, Rank 7 out of 27.

Shared baseline: last place in the ranking	6.5
Rated power: 2 400 w ; 22 perform worse, 7 perform better, 3 are tied (including this model), among the 32 catalogue models with this specification verified	+2.3
Rated power score	8.8/10

Calculation: (22 + 3 ÷ 2) ÷ 32 = 73.44% of the ranking; 6.5 + 73.44% × 3.1 = 8.8/10, rounded to one decimal place.

Battery capacity: 8.4/10

Ampace Andes 1500 scores 8.4/10 on this criterion. Across the 26 product pages on the site with a score for this criterion, the average is 8.1: above average, Rank 11 out of 26.

Shared baseline: last place in the ranking	6.5
Battery capacity: 1 462 wh ; 18 perform worse, 12 perform better, 1 are tied (including this model), among the 31 catalogue models with this specification verified	+1.9
Battery capacity score	8.4/10

Calculation: (18 + 1 ÷ 2) ÷ 31 = 59.68% of the ranking; 6.5 + 59.68% × 3.1 = 8.4/10, rounded to one decimal place.

Equipment: 6.6/10

Ampace Andes 1500 scores 6.6/10 on this criterion. Across the 28 product pages on the site with a score for this criterion, the average is 8.1: below average, Rank 27 out of 28.

Our full methodology

For your home backup power needs

You want to prepare your home for outages by identifying which appliances should take priority for power. You know their power consumption and are willing to adjust how they run to suit the available energy reserve. The Andes 1500 fits this approach, provided you confirm that its sockets and charging requirements suit your backup plan.

The Ampace Andes 1500 is designed for home backup power, with an energy reserve intended to run appliances during an outage. Its 2400 W rated output and 1462 Wh LiFePO4 battery are its main strengths, but several practical specifications remain undisclosed.

What can the 2400 W rated output and 3600 W peak output power?

The rated output of the Andes 1500 indicates the stated power level for running connected appliances. When planning your home backup power supply, add up the power requirements of the equipment you want to run simultaneously. This total must stay within the 2400 W rated output, while also accounting for each appliance's startup requirements.

The manufacturer states a peak output of 3600 W. This is not continuously available power, and its duration is undisclosed. It therefore cannot, on its own, guarantee that a particular appliance will start. Check the appliance's electrical requirements and the conditions specified in the documentation. The number of 230 V sockets is also undisclosed, a crucial consideration when planning connections.

The 1462 Wh capacity of the Andes 1500 needs to match your backup power requirements

Capacity indicates the energy reserve, rather than directly telling you how many hours your home can be powered. The theoretical calculation involves dividing capacity in Wh by total power consumption in W. However, it does not account for conversion losses or the power station's own consumption. Actual runtime therefore cannot be stated from this specification alone.

To choose, identify your priority appliances and their power consumption, then the backup duration you need. The battery uses LiFePO4 cells, but neither a cycle count nor a remaining capacity threshold is disclosed. Mains charging time and support for an expansion battery are also undisclosed. These details affect preparations for an extended outage or outages occurring close together.

Which alternative should you compare with the Andes 1500 and its 2400 W output and 1462 Wh capacity?

A suitable alternative must meet the same home backup power needs. Compare rated output, which determines which appliances can run simultaneously, separately from capacity, which affects runtime. A competing model exceeding 2400 W but offering less than 1462 Wh would favour power over energy reserves. Conversely, greater capacity would not be enough if its output were insufficient for your appliances.

We do not select a named competitor without verified specifications that allow a reliable numerical comparison. To distinguish between the models you are considering, also ask about weight, available sockets and charging time. These details are undisclosed for the Andes 1500 among its confirmed specifications. This lack of confirmation does not mean the corresponding features are absent.

Our final verdict on Ampace Andes 1500

The Andes 1500 deserves consideration if you want an energy reserve for priority appliances during an outage. Your choice should start with their power consumption and the backup duration you need, rather than the stated maximum output alone.

Things to bear in mind

Its main limitation is a finite energy reserve, which drains faster as power consumption increases. It therefore does not guarantee an extended power supply for your entire home. Also check the connections and charging options before incorporating it into your backup plan.

Our verdict:

Our analysis highlights a convincing combination of output and capacity, with a more measured assessment of its features. The Andes 1500 is a credible option for home backup power, provided you confirm the practical specifications required for your setup.

Frequently asked questions

How do you work out which appliances to connect simultaneously?

Add up their running power requirements and compare the total with the 2400 W rated output. Also check their startup requirements and connection compatibility. The stated peak output alone does not guarantee that an appliance is compatible.

How can you estimate runtime?

Divide 1462 Wh by the total power consumption of the devices in W to obtain a theoretical runtime in hours. Actual runtime will be shorter, notably due to conversion losses and the station’s own power consumption. Devices with variable power consumption require an adjusted estimate.

Can it deliver 3600 W continuously?

No, this figure is the stated peak power. Rated power is 2400 W. As the permissible peak duration is not specified, do not use this figure to size your continuous power supply.

Can it power the whole home during an outage?

Its focus on home backup does not guarantee that it can power the entire home. The combined power requirements and energy consumption of your equipment determine what can be powered and for how long. Prioritise a group of essential devices whose requirements you have checked.

What does LiFePO4 mean?

It refers to a lithium iron phosphate battery. This technology is confirmed for the Andes 1500, but it does not establish a precise cycle count or a guaranteed lifespan for this model.
