The short answer on deep cycle battery vs power station: pick a power station if you want AC outlets, an inverter and charging handled in a ready-to-use box you can carry and plug in, and pick a deep cycle battery if you are wiring your own bank and will add the inverter, charger and outlets yourself. We compared the listings on this page for what each listing states: what is in the box, stored capacity, outlets and output figures, recharge options and warranty terms. The stations lead on convenience and stated output, while the battery is the flexible, expandable option for a custom setup.

Specifications are manufacturer rated as listed, collected 22 October 2026.
What each side includes
A power station is an all-in-one box. The GRECELL lists 11 outlets, including 4 AC outlets, plus an LCD screen. The BLUETTI lists six AC outlets, 14 versatile ports and app control, with an expansion battery shipped separately. A deep cycle battery is storage only: the NERMAK listing includes two 12V batteries with F2 terminals and nothing else, so the inverter, charger and outlets come from the rest of your build. The GRECELL even describes a UPS mode that switches to battery within 10ms during an outage for equipment below 1800W, which shows how self-contained the station side is.
Stored energy and output
The stations state storage in watt-hours: the BLUETTI lists 5529.6Wh and the GRECELL lists 1843.2Wh. The NERMAK lists 12.8V and 10Ah per battery, which uses different units, so do not line the figures up directly. On output, the BLUETTI states 3840W continuous with 7680W surge, and the GRECELL states 2400W with 4800W surge. The NERMAK states 10A continuous discharge and 30A peak for under 5 seconds, which is a battery figure, not an inverter figure. Only compare a spec where the listings on both sides state it clearly; output in watts is a station figure here, and the battery listing leaves it unclear.
Recharging
The stations recharge several ways. The GRECELL states 1.6 to 2 hours from a 1200W AC input, 1.8 hours or less with combined solar and AC, 3 hours with an 800W solar input, or from a car outlet. The BLUETTI states 80% in 45 minutes from AC, solar input of 2400W built-in or 6400W expanded, and generator charging. The NERMAK charges at 5A with a 14.6V charging voltage, and the maker warns that an automatic SLA charger may not fully charge it, so a LiFePO4 charger is needed.
What the listings leave unclear
The NERMAK spec table lists the battery height as 3.91 inches in one row and 3.7 inches in another, so measure your tray before ordering. The BLUETTI spec table files 5529 watt-hours under Output Wattage while the title and bullets call it storage capacity, so use the title figure. The GRECELL listing names no battery management system, so its safety line stays empty. The BLUETTI listing states no warranty term at all. None of the listings state UL, ETL or CSA certification.

Detailed Review
The listing states the Apex 300 power station plus a B300K expansion battery, shipped separately, for 5529.6Wh of LiFePO4 storage, six AC outlets at 3840W with 7680W surge, simultaneous 120V/240V output, 14 versatile ports, app control and a BLUETOPUS AI-BMS. Charging options include solar (2400W built-in, 6400W expanded), AC (80% in 45 minutes) and generator charging stated as 95% compatible, and the listing claims 6000+ cycles to 80% capacity, a 17-year lifespan and CNAS certification. The spec table files 5529 watt-hours under Output Wattage, so use the title and bullets for the capacity figure.
Who it's for: owners who want the largest stated storage and the strongest stated output here in one box. Who should skip it: anyone who needs a stated warranty term, which this listing does not give.
Its Solar Score of 9.7/10 comes from performance 32/35, build 22/25, value 20/25, safety 8/10 and warranty 0/5: 82 of 100 points, placed on our 9.2 to 9.8 scale.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For this mixed group, safety means a battery management system or another protection the listing names: the BLUETTI states its BLUETOPUS AI-BMS, the NERMAK states a 10A BMS, and the GRECELL names none. Two of the three state a warranty term, 1 year and 2 years, while the BLUETTI states none. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| BLUETTI Apex 300 | 9.7 | 32 | 22 | 20 | 8 | 0 |
| GRECELL H2400 | 9.5 | 29 | 20 | 20 | 0 | 3 |
| NERMAK 12V 10Ah 2-Pack | 9.5 | 26 | 20 | 19 | 6 | 1 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Deep cycle battery vs power station: which should you choose?
Choose a power station if you want the simplest path to backup power. The BLUETTI suits the largest stated loads and storage here, with 3840W of stated AC output and simultaneous 120V/240V. The GRECELL suits a smaller but still capable box, with 11 stated outlets, stated UPS behavior and a 2 year warranty. Choose the deep cycle battery if you are building or expanding a 12V bank: the NERMAK two-pack gives you 10Ah batteries with stated BMS protection that wire in series or parallel, at far less stated weight than either station.
| If you need | Look at |
|---|---|
| The largest stated storage | BLUETTI Apex 300, 5529.6Wh |
| A ready box with outlets and UPS stated | GRECELL H2400, 11 outlets, UPS within 10ms |
| A bare battery for your own build | NERMAK 12V 10Ah 2-Pack, 12.8V, 10Ah, F2 terminals |
| A stated warranty term | GRECELL H2400, 2 year manufacturer |
Sizing Notes
- Match loads to stated output: the BLUETTI lists 3840W continuous and 7680W surge, the GRECELL lists 2400W continuous and 4800W surge, and the NERMAK lists 10A continuous discharge with no inverter included.
- Compare storage in matching units: the stations state watt-hours, the battery states volts and amp-hours, so do not convert one to the other.
- Check the tray against the stated footprint, noting the NERMAK spec table lists two different heights, 3.91 and 3.7 inches.
- If you build on the deep cycle battery, match every charging source to a LiFePO4 profile at the stated 14.6V charging voltage.
- Fuse the positive lead as the manual directs.
Frequently Asked Questions
What does a power station include that a deep cycle battery does not?
An inverter, outlets and charging in one box. The GRECELL lists 11 outlets and a UPS mode, and the BLUETTI lists six AC outlets with simultaneous 120V/240V. The NERMAK is two bare batteries with F2 terminals, so you add those parts yourself.
Which option here stores the most energy?
The BLUETTI lists 5529.6Wh, then the GRECELL at 1843.2Wh. The NERMAK lists 12.8V and 10Ah per battery, which uses different units, so compare watt-hours to watt-hours.
How do the recharge times compare?
The GRECELL states 1.6 to 2 hours from a 1200W AC input and 3 hours with an 800W solar input. The BLUETTI states 80% in 45 minutes from AC. The NERMAK charges at 5A, and the maker warns a standard SLA charger may not fully charge it.
Do any of these state a warranty?
The GRECELL states a 2 year manufacturer warranty and the NERMAK states 12 months. The BLUETTI listing states no warranty term.
What cycle life do the listings claim?
The BLUETTI claims 6000+ cycles, the GRECELL claims 3500+, and the NERMAK claims 2000+ against 200 to 300 stated for traditional lead acid batteries.
