What Is Powertron P8000 Battery?
The Powertron P8000 (possibly referencing Patriot PB8000 based on available data) is a compact lithium-polymer power bank with an 8,000mAh capacity at 3.7V nominal voltage. Designed for portable device charging, it features dual USB outputs (5V/1A and 5V/2.1A), Micro-USB input, and compatibility with smartphones, tablets, and gaming devices. Its 221g lightweight aluminum casing prioritizes portability while providing LED status indicators for charge monitoring. Pro Tip: Use dedicated 1A chargers to avoid exceeding thermal limits during recharging cycles.
What are the key technical specifications?
This power bank utilizes a single-cell LiPo configuration delivering 29.6Wh energy (8,000mAh × 3.7V). Input accepts 5V/1A via Micro-USB, requiring ≈6 hours for full recharge. Output prioritizes 2.1A port for tablets while maintaining 1A standard for phones. Dimensions of 126×77×13mm make it comparable in size to smartphone wallets.
The discharge curve shows voltage stability within ±5% until 20% residual capacity. For perspective, a full charge replenishes 2.5 iPhone 12 cycles. Why does this matter? Consistent voltage prevents device charging hiccups during critical usage phases. Practically speaking, the P8000 serves best as emergency backup rather than primary charging solutions for multiple devices.
| Feature | P8000 | Typical Competitor |
|---|---|---|
| Weight | 221g | 250-300g |
| Output Ports | 2 (1A + 2.1A) | Single 2.4A |
| Recharge Time | 6 hours | 4-5 hours |
How does it compare to Huawei 22.5W SE?
Though both target mobile users, Huawei’s 10,000mAh unit supports SCP fast charging protocols (22.5W max) versus P8000’s basic 10W output. The trade-off? Huawei’s 295g weight and thicker profile sacrifice portability for speed. Charging benchmarks show Huawei fully charges a Mate 40 Pro in 1.2 hours vs. P8000’s 2.8 hours. But what if you prioritize pocketability? The P8000’s slimmer design slips easily into jeans pockets without bulk.
Battery chemistry differences emerge too—Huawei uses higher-density cells enabling 33% more capacity despite only 19% size increase. However, repeated fast charging accelerates Huawei’s capacity degradation to 80% after 300 cycles vs. P8000’s 500-cycle rating. Transitionally, users must choose between rapid charging or longevity.

FAQs
Yes, but only older models—the 2.1A port delivers 10.5W, sufficient for basic iPad charging but too slow for 30W+ Pro models.
Is passthrough charging supported?
No, simultaneous charging/discharging isn’t advised due to limited power management IC capabilities.
