Anker SOLIX S5000 Announced: 5,024Wh Power Station With 4,500W Output
Anker’s new wheeled 5kWh power station is aimed at home backup, RV and off-grid use. Here are the announced specs, pricing and claims, plus what still needs independent testing.
01Quick Context
Anker has announced the SOLIX S5000, a wheeled portable power station with a 5,024Wh battery and 4,500W rated output. Anker positions it as the longest-lasting 5kWh power station in its class, based on its own internal testing against selected competitors.
This post covers what Anker has published. We have not tested the S5000 yet, so the runtime, efficiency and lifespan figures below are Anker’s claims. Below, we explain the key terms, list the specs, and point out where sources disagree.
02The Short Answer
What stands out on paper
- 5,024Wh of LFP battery capacity with 4,500W rated output and 8,000W peak
- Dual 120V and 240V output, including an L14-30R outlet and a TT-30R RV outlet
- Zero to 100% in as little as 99 minutes on a 240V supply
- Up to 3,000W of solar input across two inputs
- Expandable from 5kWh to 30kWh with up to five additional batteries
What still needs checking
- Runtime, efficiency and lifespan figures come from Anker’s internal testing
- Sources disagree on the value of the early-access bonus
- Expansion battery pricing has not been announced
- Anker has announced US availability only
The big thing to know: the S5000 weighs 97 lb. Its headline runtime claims assume specific devices and conditions, so treat them as the starting point for your own planning, not a guarantee.
03What It Can Power, According to Anker
Big numbers on a spec sheet only matter if they translate to real life. Anker’s runtime examples combine efficiency with a light load, so the figures below are best-case scenarios from its own tests.
| Load | Anker’s stated runtime | Test notes |
|---|---|---|
| Refrigerator, Wi-Fi router, coffee maker, lights and phone | Up to 48 hours | Combined load on one charge, based on Anker’s internal testing |
| Refrigerator alone | Up to 86 hours | 700L fridge, room at 77°F, fridge at 37°F, freezer at 0°F |
| Window air conditioner | Up to 25 hours | Tested individually by Anker |
Anker says actual runtime depends on the connected devices and environmental conditions. Heavy loads will shorten these figures, and no independent results are available yet.
04New to Power Stations? Start Here
A portable power station stores electricity in a battery and delivers it through outlets, so it does not burn fuel the way a generator does. The S5000 uses lithium iron phosphate (LFP) cells, a battery chemistry that Anker says supports long service life.
Three terms will help you read any spec sheet:
- 120V vs. 240V: 120V powers most household outlets and small appliances. 240V powers larger jobs such as central air and electric ranges. The S5000 supports both.
- UPS switchover: how quickly a unit switches to battery power during a grid outage. Anker rates the S5000 at 10ms.
- Idle draw: the power the station uses on its own while nothing is plugged in. Anker lists 8.8W in 120V mode.
As a simple rule, add up the watts of everything you plan to use at the same time, then leave room to spare.
05Efficiency and Runtime Claims
Anker’s main argument is efficiency. Its OptiSave 2.0 technology is meant to send more of the battery’s stored energy to your devices rather than losing it inside the unit. Here is how the claims line up.
| Claim | Anker’s figure | Comparison |
|---|---|---|
| Efficiency at a 1,000W light load | Up to 96% | Anker cites an industry average of 86% in its own comparison |
| Idle draw, 120V mode | 8.8W | Listed for 120V mode only |
| TÜV SÜD runtime rating | A+ Runtime | Anker says it is the first 5kWh power station to earn this rating |
Anker also says the unit can stay on standby for up to 21 days. Efficiency claims are most relevant at light loads, so heavier appliances will see less of this benefit.
06Charging and Solar Input
Charging speed depends heavily on the outlet you use. Anker’s published figures show a large gap between a 240V supply and a standard 120V outlet.
| Input | Rating | Notes |
|---|---|---|
| 240V supply | Up to 4,500W | Zero to 100% in as little as 99 minutes |
| 120V outlet | Up to 1,800W | The 99-minute figure does not apply on 120V |
| Solar input | Up to 3,000W | Across two solar inputs |
07Battery Life
Anker rates the battery for 6,000 charge cycles before it drops to 80% of its original capacity, or 10,000 cycles before it drops to 60%. It estimates a service life of about 15 years at one to two cycles per day. Product coverage is five years, and Anker says actual battery life depends on usage and environmental conditions.
Read the lifespan claim carefully
The 15-year estimate assumes one to two cycles per day and a battery that still holds more than 60% of its original capacity. That is a long-term projection, not something anyone can verify on day one.
08Connecting It to Your Home
Anker says the S5000 can connect through a transfer switch or inlet box, or plug straight into appliances. Expansion is also part of the design. Anker lists configurations from 5kWh to 30kWh with up to five additional batteries, but it has not announced expansion pricing.
Safety first
Never plug a portable power station or generator into a standard wall outlet to backfeed your house. That can push power back into the utility grid and put line workers at risk. For a permanent setup, have a licensed electrician install a properly rated inlet box or transfer switch that meets your local code.
09How It Compares
Forbes compared the S5000 with two other large-capacity units. The Jackery Explorer 5000 Plus stores a similar 5,040Wh, but it weighs 134.5 lb. The BLUETTI EP500 Pro has a 5,100Wh battery and weighs 182 lb, although its lower output and different design make it a less direct comparison.
The S5000 is 97 lb, with built-in wheels, a pull rod and 58 liters of volume. For a close alternative to consider, see our EcoFlow Delta Pro 3 review, which covers a similar class of power station.
| Model | Battery | Weight |
|---|---|---|
| Anker SOLIX S5000 | 5,024Wh | 97 lb |
| Jackery Explorer 5000 Plus | 5,040Wh | 134.5 lb |
| BLUETTI EP500 Pro | 5,100Wh | 182 lb |
10Portability and Design
Anker says the S5000 is the smallest and lightest 5kWh power station in its class, based on its own comparison of selected models. At 97 lb and 10.6 x 22 x 15.2 inches, it has built-in wheels and a pull rod for moving it around. Anker also describes a telescoping handle that makes it easier to store against a wall.
The front panel and outlet layout are part of the announcement. The US model has NEMA 5-20R outlets, a TT-30R RV outlet and an L14-30R outlet for 240V loads, plus USB-A and USB-C ports. Anker rates operating noise at 30dB.
