The Numbers on the Spec Sheet

Battery capacity separates this portable power station most, and 155Wh measures how much electrical energy the battery can store and later supply.

Before You Buy: Portable Power Station Checklist

The first thing to check is whether 155Wh and 100W match the device you want to run. A portable power station with those numbers suits light loads, not high-draw appliances.

• ☐ Confirm your AC device needs no more than 100W — anything higher will trip the inverter, so you would need to return this unit or buy a larger battery power station.
• ☐ Check your runtime need against 155Wh — if you expect longer backup than that energy store can supply, you will need a bigger unit instead of living with a short run time.
• ☐ Budget for 110V AC only — if your gear needs another outlet voltage, you will need a different portable battery generator or an adapter that may not fit the load.
• ☐ Confirm solar charging is acceptable with panels not included — you must buy the panel setup separately, or you will not have solar charging at all.
• ☐ Measure the panel output you plan to use — the built-in MPPT controller can manage solar input, but the panel wattage is not stated, so an undersized setup will charge slowly.
• ☐ Check whether 3 x 5V USB outputs and 3 x 12V DC outputs cover your gear — if they do not, you will need adapters or a different portable power station.

Do not buy this if you need more than 100W on AC or a larger energy reserve than 155Wh.

What performance in practical terms means for this battery power station

What the AC output can power from this battery power station

SPS-155 gives you 100W from its AC outlet, with a 110V outlet voltage. That means it can serve light AC loads, such as a small TV or a CPAP setup, as long as the device stays within that power limit.

The 100W ceiling is the key constraint here. A mini fridge can start with a higher surge than its running draw, so you should compare its startup wattage against 100W before you count on this portable power station for that job. Short answer: keep the load modest.

Which charging inputs refill this battery power station

SPS-155 accepts solar panels, a car port, and AC wall outlets. That gives you three ways to refill a 155Wh battery, so you can top it up from a wall at home, a vehicle on the road, or panels in the field.

The solar option is useful, but the panels are not included, so you need to budget for them separately if off-grid charging matters to you. The 155Wh capacity is also the runtime limit, not the recharge limit, so a phone, laptop, or fan will draw from that stored energy until it is spent.

Why the portable build makes this battery power station easy to move

The SPS-155 weighs 3.48lbs and includes an ergonomic handle. That makes it easy to move between a desk, a car, and a campsite without treating it like a fixed backup unit.

Its 42,000mAh rating and 155Wh storage describe a compact energy reserve, not a long-duration house backup. If you want longer runtime for a laptop or fan, compare the stored watt-hours first; if you want more device flexibility, check whether the 3 x 5V USB outputs and 3 x 12V DC outputs cover your gear without adapters.

Where the SPS-155 Sits Among the Alternatives

AIMTOM’s SPS-155 is the lightest-capacity option in this comparison at 155Wh, and it keeps the same 110V AC outlet voltage as four rivals. At around $126, it also lands between the cheaper PROGENY and ALLPOWERS units and the pricier GENSROCK, CTECHi, and DaranEner models.

• PROGENY’s 299Wh battery gives it much more stored energy than the SPS-155. That matters if you need longer runtime from the same charge.
• ALLPOWERS lists 300W max input, while the SPS-155 has a built-in MPPT controller and can charge from solar panels, a car port, or AC wall outlets. For a small setup, that leaves you more charging paths to work with.
• GENSROCK weighs 5.5 pounds, while the SPS-155 comes in at 3.48 pounds. If you plan to carry it by hand, the lighter unit is easier to move.
• CTECHi uses LiFePO4 batteries and says 3,000 cycles of lifespan.
• DaranEner lists 600W continuous power and 1 USB-C PD 100W port, while the SPS-155 has 100W AC output and three 5V USB outputs. That makes DaranEner the better pick for higher-draw AC gear or a USB-C laptop charge.

Pick DaranEner instead if you need to run gear that wants more than 100W from AC. The SPS-155 suits smaller loads, such as a phone, a lamp, or a low-draw charger, but its AC side is the limit to watch.

What the price buys compared with similar portable power stations

The AIMTOM SPS-155 sits at around $126, while similar portable power station products we compared against range from $123.44 to $129.98, with an average of $127. That puts it about $1 under the average, so the price is in line with the field rather than a bargain outlier. The trade-off is in the stored energy and inverter size: 155Wh and 100W keep it in a small backup class, so you are paying for a compact unit rather than long runtime or high-draw appliance support.

If you need a light backup for phones, small USB loads, or short AC use, the SPS-155 makes sense at this price. Its 3.48lbs weight and 110V/100W AC output suit modest loads, but the 155Wh battery will not buy much runtime for larger devices. If you need more stored energy or more AC headroom, the money goes farther on a larger portable power station, and choosing this one would mean a return or replacement sooner than planned.

You might also find budget-friendly options for small apartments useful if you need a compact unit under $500.

What It Takes to Run the SPS-155

Getting the SPS-155 ready for use

The SPS-155 needs an AC wall outlet, a car port, or solar panels before it can do anything useful.

1. Unpack the SPS-155 and confirm the 110V AC outlet rating before you plan any AC load.
2. Place it where the 3.48 lb body and ergonomic handle leave room for the unit and its cables.
3. Connect your chosen source to one of the charging methods: AC wall outlet, car port, or solar panels.
4. Plug devices into the USB outputs, DC outputs, or 110V AC outlet, matching each device to the correct output type.
5. Keep AC use within the 100W output limit so the connected load stays within the inverter rating.

Warranty and support: what to check for the SPS-155

Warranty cover for the SPS-155 differs by seller and country.

• Confirm the return window for the 100W inverter, because an outlet mismatch can make the unit unsuitable for your load.
• Confirm whether the 155Wh battery is covered as a separate part, because stored energy is the core value here.
• Confirm support for the built-in MPPT controller, because that part affects solar charging and is not user-serviceable.
• Confirm the policy for the AC wall charging path, because that is one of the three stated charging methods.

The first day it arrives, charge the SPS-155 from a known-good AC wall outlet and verify that the 110V AC output and USB outputs power your devices.

Questions Buyers Ask About This Portable Battery Generator

How noisy does the AIMTOM SPS-155 get when the AC outlet is on or when it’s charging?

The SPS-155 listing does not state a noise figure for AC use or charging. If quiet operation matters to you, look for a decibel rating; without one, noise remains unknown from the data here.

Can the AIMTOM SPS-155 run small appliances?

No, the SPS-155 is rated for 100W AC output, so it is not sized for many small appliances that need more surge or running power. It still gives you 110V AC, plus USB and DC outputs, so low-draw electronics fit the better part of its use case.

How long will the AIMTOM SPS-155 power my devices?

The SPS-155 stores 155Wh, which is the figure that matters for runtime. That amount is useful for short backup needs, but runtime still depends on each device’s draw, and that draw is not stated here.

Is the AIMTOM SPS-155 worth buying for travel or backup?

If you need a compact 155Wh portable power station with 110V AC, three 5V USB outputs, and three 12V DC outputs, the SPS-155 has the right mix for light use. Around $126, it is aimed at smaller loads rather than long outages or higher-draw appliances.

Safety is a priority, so review the official safety standards to understand the necessary certifications for your device.

Final Verdict on the SPS-155

You should choose the AIMTOM SPS-155 if you need a 110V portable power station for light AC loads and USB charging, and you want to stay around $126. Its 155Wh battery and 100W AC output keep it in the compact end of the category.

The strongest fact here is the 100W AC output. That output level suits small electronics and low-draw gear, while the 155Wh battery limits runtime for larger loads. The 4.3 average from 3,273 buyer ratings adds useful context, but the wattage is the real decision point.

Skip it if: you need to run higher-draw appliances, or you want a portable power station with longer runtime from a larger battery.
