POE-932P-LFP Mini DC UPS 36W 28000mAh | LiFePO4 PoE UPS 24V/48V for Router, CCTV & DVR

POE-932P-LFP Mini DC UPS Features and Appearance

The POE-932P-LFP is a dependable 28000mAh mini UPS from ulinkeep, built for network and security scenarios that need long backup time. As a compact uninterruptible power supply (UPS), it keeps DC devices online when mains power fails.

When the grid drops, this 28000mAh mini UPS switches over in 0 ms with no interruption, so routers, modems, PoE cameras and DVR/NVR keep running without rebooting. The whole unit is a pure-black flat square box, 230 × 125 × 38 mm and 1.0 kg net weight, and lies flat in a weak-current box, on a desk or on a cabinet shelf.

The front panel of this 28000mAh mini UPS is clearly marked by color zones: the blue zone has three DC output ports (5V / 9V / 12V) and also integrates a USB port, a Type-C port and a RESET button; the yellow zone has the SELECTOR 24V/48V switch and two RJ45 ports (LAN and PoE); the green zone is the 100–240VAC input. Above the panel, a row of 8 LED battery indicators (25%, 50%, 75%, 100%) and the 12V/9V gear lights show the status in real time.

POE-932P-LFP Mini DC UPS Specifications

Inside, this 28000mAh mini UPS uses a LiFePO4 (lithium iron phosphate) battery pack rated at 89.6Wh — longer cycle life and better thermal safety than ordinary ternary lithium. Outputs run in parallel: DC ports 5V/3A, 9V/2A and 12V/3A; the USB port supports 5V/3.0.

The Type-C PD port fast-charges at the same ratings, and the PoE (Power over Ethernet) port offers 24V/1.5A and 48V/0.75A, carrying data and power over one network cable. Maximum total output is 36W. Input is 100–240VAC wide voltage for worldwide use; transfer time 0 ms, with short-circuit protection. Single package is about 30 × 25 × 15 cm with a gross weight of 2.0 kg.

POE-932P-LFP Customization Cases and Craft Details

This 28000mAh mini UPS has already completed two overseas OEM batches. One is an Afghan wholesaler: the customer needed a large-capacity configuration to power PoE cameras and a DVR system. At the PCBA stage we built independent sampling protection for the PoE 24V/48V dual circuits according to their receiving parameters, and the 28000mAh LFP cells were resistance-matched cell by cell, ageing-screened and then assembled into the case.

The black plastic housing is injection-molded, and the color-zoned front panel silk printing (blue / yellow / green port zones) is printed in register with the customer’s artwork; the seams are tight and dust-sealed. Before mass production, every unit is tested for all five output channels, transfer time and protection functions. The other customer is a Middle East wholesaler: from neutral color box and multi-language manual to DC plug specifications, everything was sampled in one round; after the sample passed charge/discharge cycles and high/low temperature tests it was sealed as the golden sample, and repeat orders are produced exactly against it.

POE-932P-LFP Mini DC UPS B2B Application Scenarios

Security & surveillance projects: as a 28000mAh mini UPS, POE-932P-LFP sits in the weak-current well; the PoE port powers 48V cameras and the DC port backs up the NVR — the 89.6Wh large battery keeps the whole recording line running during grid maintenance.

Chain stores & checkout networks: one line powers the router at the counter and another connects PoE payment and scanning devices; when the shopping-area power trips, receipts still print normally.
SME office weak-current rooms: centralized backup power for the main router, modem and IP phones; remote meetings stay online during outages.
Smart access control & community intercom: 12V access controllers and video door phones connect directly; residents keep passing face and card checks during property power cuts.
Hotels & apartments: guest-room routers and network boxes go offline as soon as power fails — the 3.8 cm thin unit fits into a bedside table or network box, and guest complaints drop noticeably.

POE-932P-LFP OEM and ODM Capability

ulinkeep supports OEM/ODM: custom color box design in 3 days, samples delivered in 7 days, plus free spare-part replacement and online technical support during the cooperation.
