LASTAR Portable vs Competitors: Which Power Bank Wins?Power banks are essential for staying connected on the go. In this comparison, we evaluate the LASTAR Portable against several popular competitors to determine which power bank comes out on top across performance, design, price, and real-world usefulness.
Quick overview
- LASTAR Portable: A compact, travel-oriented power bank known for a balance of capacity and portability.
- Competitors considered: Anker PowerCore series, RavPower (now rebranded as RAVPower/AGM variants), Aukey, and Xiaomi power banks. Each competitor offers models targeting different priorities: fast charging, high capacity, ultra-compact size, or value.
Key comparison criteria
We judge each power bank on:
- Capacity (mAh) and usable energy
- Output power (W), port types, and charging speed
- Input (recharge) time and convenience
- Size, weight, and build quality
- Additional features (pass-through charging, USB-C PD, wireless charging, LED indicators)
- Price and value for money
- Reliability and warranty/customer service
Capacity and usable energy
Battery capacity (mAh) is the headline number, but actual usable energy depends on voltage conversion and efficiency. Typical conversion losses mean you’ll get about 60–90% of rated capacity depending on the power bank’s design and the device being charged.
- LASTAR Portable: Often sold in 10,000–20,000 mAh variants. Good balance between capacity and portability for daily carry.
- Anker PowerCore: Ranges widely. High-end models (20,000 mAh+) typically use high-efficiency circuitry, yielding reliable usable energy.
- RAVPower: Similar capacity range with competitive efficiency, often with slightly better throughput on certain models.
- Aukey: Value-oriented; capacities are comparable but occasionally have slightly lower efficiency.
- Xiaomi: Typically good energy density and competitive pricing; solid usable capacity for the price.
Output power and charging speed
Output power determines how fast your devices charge. USB-C Power Delivery (PD) and Quick Charge (QC) support are increasingly standard.
- LASTAR Portable: Many models include USB-C PD (18–30W on midrange units). Good for phones and small tablets; not always sufficient for most laptops unless it’s a higher-wattage LASTAR model.
- Anker PowerCore: Offers models up to 45W–60W PD. Best for fast charging and some USB-C laptops in certain models.
- RAVPower: Strong PD support on many models; comparable to Anker in speed.
- Aukey: Often supports QC and PD; performance is model-dependent.
- Xiaomi: Good PD support in higher-end models; excellent for phones and many tablets.
If you need to charge a laptop frequently, choose a model with 45W+ PD. For phones, 18–30W PD is usually sufficient.
Input (recharge) time and convenience
Recharge time depends on the input charging rate. Dual-input and high-wattage input reduce downtime.
- LASTAR Portable: Midrange input speeds (often 18–30W); recharges overnight or faster with PD input on supported models.
- Anker & RAVPower: Offer faster recharge (30W–65W on some models), meaning full recharge in 2–4 hours for many capacities.
- Aukey & Xiaomi: Varies; some support fast input, others are slower.
Size, weight, and build quality
- LASTAR Portable: Designed for portability; lightweight and pocket-friendly for its capacity class.
- Anker: Premium build quality, often slightly heavier due to robust enclosures.
- RAVPower: Solid build; design varies across models.
- Aukey: Functional but sometimes less refined finish.
- Xiaomi: Slim profiles with metal finishes on some models; good design for the price.
Additional features
- USB-C Power Delivery: Present across higher-tier models from all brands; LASTAR often includes PD on newer units.
- Multiple ports: Anker and RAVPower commonly offer multiple high-power outputs, useful for charging several devices simultaneously.
- Pass-through charging (charge device while recharging power bank): Available on select models; check the specific model as behavior varies.
- Wireless charging: Some LASTAR and competitor models include Qi wireless charging pads—useful for convenience but slower charging.
- Indicators and safety: Overcharge/overheat/short-circuit protection is standard among reputable brands.
Price and value
- LASTAR Portable: Priced competitively; good value when balancing price, capacity, and portability.
- Anker: Slightly higher price but strong reputation for reliability—worth the premium for users who want consistent performance and customer support.
- RAVPower: Often undercuts Anker while providing similar specs—great value.
- Aukey: Budget-friendly; best for price-conscious buyers.
- Xiaomi: Excellent value in markets where available; high energy density for price.
Comparison table (generalized):
| Brand/Focus | Typical Capacity | PD Support | Portability | Price Range | Strength |
|---|---|---|---|---|---|
| LASTAR Portable | 10k–20k mAh | 18–30W PD often | High | Mid | Balanced portability/value |
| Anker PowerCore | 10k–26k+ mAh | up to 60W PD | Moderate | Higher | Reliability & fast charging |
| RAVPower | 10k–26k+ mAh | up to 65W PD | Moderate | Mid | Competitive specs/value |
| Aukey | 5k–20k+ mAh | PD/QC on some | High | Low–Mid | Budget value |
| Xiaomi | 10k–20k+ mAh | up to 45W PD | Slim | Low–Mid | Price vs energy density |
Reliability, warranty, and customer support
- LASTAR Portable: Generally reliable with standard protections; warranty terms vary by seller—check before buying.
- Anker: Excellent reputation for customer support and warranty handling.
- RAVPower: Good support historically; check current warranty specifics.
- Aukey & Xiaomi: Varies by region and retailer; brand reputation is mixed but improving.
Which one wins?
- If you want the best balance of portability and everyday capacity at a reasonable price: LASTAR Portable is a strong choice.
- If you prioritize fastest charging and laptop support: Anker or RAVPower models with 45W+ PD are better.
- If budget and value are top concerns: Aukey or Xiaomi deliver the most capacity per dollar in many markets.
Buying recommendations (by use case)
- Daily carry/commute (phones, earbuds): LASTAR Portable 10k–15k mAh.
- Travel (multiple charges, small laptop): Anker or RAVPower 20k mAh with 45W+ PD.
- Budget long-capacity: Xiaomi or Aukey 20k mAh models.
- Wireless convenience: Choose a model with Qi charging (verify pad power output).
Final verdict
No single power bank is objectively best for every user. For most people who want a compact, reliable all-around unit, LASTAR Portable wins on portability and value. For users who need higher wattage fast charging for laptops or multiple-device simultaneous fast charging, Anker or RAVPower models take the lead.
