INTRODUCTION

    High output and capacity portable power stations have evolved into a core utility for anyone operating beyond fixed electrical infrastructure. Their ability to deliver sustained, clean AC power, alongside stable, low‑ripple DC outputs, makes them indispensable for running heavy‑draw equipment, sensitive electronics, and DC‑native devices alike. From power tools, cooking appliances, lighting arrays, fans and even portable air conditioners to TV's, projectors, drones, routers, radios, and camera gear, they provide a reliable energy backbone without the noise or constraints of traditional generators. They support field technicians, content creators, campers, and homeowners by offering dependable backup during outages and flexible power for off‑grid workflows. In this category, the ALLPOWERS R2500 V2 enters as a straightforward high‑capacity option.

    ALLPOWERS INDUSTRIAL INTERNATIONAL LIMITED is a solar energy technology company integrating R&D and production.  Our headquarter is located in Guangzhou, China. Since its establishment, the company has been committed to research and development of portable solar energy related products. The current main product categories include portable solar panel phone chargers, solar laptop chargers, portable solar semi-flexible solar panel, and solar energy storage systems. ALLPOWERS is mainly oriented to Western Europe, North America, East Asia, Eastern Europe, Middle East and other markets in more than 30 countries and regions. We have accumulated to provide solar energy products for more than 100 customers around the world, and has cooperated with many world-renowned companies or brands, including Hanergy, Hikvision, Decathlon and so on.

    For users seeking a feature‑rich power station with serious output, the ALLPOWERS R2500 V2 offers a balanced combination of capacity and control. It houses a long‑life 1920Wh LiFePO4 battery rated for 3500+ cycles, supported by a high‑performance BMS that manages over‑temperature, over‑voltage, low‑temperature discharge, overcurrent, overload, short‑circuit, and charge‑protection events. Its 2500W pure sine wave inverter (4000W surge/peak) drives four 220-240V AC outlets, while the DC side includes regulated 12V ports, Anderson, car socket, quad USB‑A outputs (18/12W), and dual 100W USB‑C PD ports (200W total) covering everything from laptops and drones to networking gear and automotive accessories. Charging flexibility is a major strength, up to 1500W AC input (2000W+ in fast mode), 1000W solar input (12-150V / 13A), 12/24V car charging, and a 2000W AC + solar dual‑input mode capable of replenishing the unit in about an hour. The integrated UPS function switches in under 15ms, keeping connected devices running during outages (up to 1500W while in UPS pass through mode), and the unit supports full Wi‑Fi/Bluetooth app control for monitoring, settings, and firmware updates. Finally, the R2500 V2 is also available with different regional plug configurations for the EU, USA and the UK.

SPECIFICATIONS AND FEATURES

PACKAGING AND CONTENTS

ALLPOWERS ships their R2500 V2 inside a plain cardboard box that just has their logo and a product drawing at the front.

A sticker with the product specifications and features is located at the rear.

Packing is all but excellent with the R2500 V2 placed between two thick pieces of foam.

Bundle is not one of the R2500 V2's strongest points since inside the box you'll only find the charging cord, battery warning paper, tips paper and the user manual.

THE R2500 V2

The 24.5Kg heavy R2500 V2 is a large portable power station measuring 456mm in length, 346mm in width and 361mm in height.

Typically, most connectors are placed at the front so from left to right we find two USB-C ports (100W each), four USB-A ports (18W/12W), USB on/off button, four AC plugs, AC on/off button, LCD screen, on/off button, car cigar port, DC out and the DC out on/off button.

The LCD screen is easy to read but it still depends a lot on the angle (one day I hope every manufacturer puts more weight on this).

On top ALLPOWERS has placed a textured area where you can place small things like your smartphone or tablet.

Taking a look at the right side, we find two battery expansion ports under a cover/door.

On the left side we find the power port, fuse and solar panel port under a similar cover/door.

ALLPOWERS is using a very effective combination of anodized aluminum fins and a fan to keep noise to a minimum.

At the rear of the R2500 V2 we find 2 stickers, one pointing to the iOS and Android smart app and one with the unit's specifications.

ALLPOWERS APP

The ALLPOWERS app is a crucial component of the R2500 V2 so you should definitely use it.

This app uses Bluetooth connectivity to look for nearby power stations by ALLPOWERS.

Main tab as with past models showcases current battery charge, remaining discharge time (based on current consumption), input/output, available connectivity (you can also turn them on and off), and Hz.

From inside the settings menu (three dots on the upper right corner) you can change the name of the device, charging mode, enable ECO mode with auto shutdown, perform a firmware update and delete the device from the app.

There are three available charging modes, mute, standard and fast.

In my case mute hovered at around 650-700W, standard between 1000 and 1200W and fast between 2000 and 2020W (these are probably affected by ambient temperature meaning you may get higher or lower input).

Instead of having an automatic firmware check and update feature the end user is required to ask ALLPOWERS for a unique code in order for that to happen (according to them this is for safety concerns).

TESTING METHODOLOGY

    In order to cover a wide range of electrical and electronic devices i decided that I’ll be using 3 different ones to test portable power stations, the VEVOR SH-C22 Bluetooth car refrigerator (DC, around 45W consumption - not continuous), Delonghi Aria Dry Light dehumidifier (AC, around 662W consumption) and a generic air cleaner (AC, around 55W consumption). Of course, my ExTech HD600 dBA meter will also be used at around 10cm away from each portable power station to record the maximum noise coming from the built-in fan/s (ambient temperature is once again set at 23 degrees Celsius for all tests).

TEST RESULTS

CONCLUSION

    Overall, the ALLPOWERS R2500 V2 delivers a compelling blend of long‑life LiFePO4 battery chemistry, robust electrical protections, dependable build quality, and a generous selection of AC and DC connectors that make it easy to integrate into a wide range of setups. Its pure sine‑wave inverter ensures stable, appliance‑safe (and more efficient compared to other power stations) AC output, which pairs well with its efficient DC ports for lower‑loss operation. The three available charging modes (via the app) add meaningful flexibility, the quiet mute mode that holds at around 650-700W, the fast 1000-1300W standard mode, and the 2000W+ fast charge mode when speed takes priority. Combined with low operating noise and efficient power delivery, especially through its DC outputs, the unit performs confidently in both home‑backup and off‑grid scenarios. The drawbacks are practical rather than critical. The R2500 V2 is undeniably heavy, and the rubber stops on the side doors can easily peel or loosen over time due to the repeated flexing of the hinged covers (in my case they fell off after opening the left right just 5 times - you can see m placing them under the top end of the right door in my pictures since they had already fallen off). It also ships without a car cigar charging cable, which feels like an omission given its versatility, and the app’s firmware‑update process requires obtaining an upgrade code directly from ALLPOWERS before you can apply new firmware (ALLPOWERS says if the battery works fine, it's not needed but still). These quirks don’t overshadow the core strengths, though, strong protections, LiFePO4 longevity, quiet operation, flexible charging, and a well‑rounded connector layout make the R2500 V2 a capable and efficient high‑output power station for users who want reliability and versatility in one unit.

    At the time of this review the latest R2500 V2 portable power station by ALLPOWERS retails for USD799 inside the USA (ALLPOWERS.COM / USD719.10 by using code NIK10 at checkout) and for 854Euros inside the EU (ALLPOWERS.EU / 768.60Euros by using code NIK10 at checkout). At the end of the day the ALLPOWERS R2500 V2 may not be the highest capacity or output model in the market but it does offer a great price/performance ratio and on top of that it’s the best model to arrive in the lab to date and so the Platinum Award is in order.
